OpenXml 学习记录 标签目录 插入文本 表格 图片
关于目录标签的一些解析可以看下这篇文章：https://www.cnblogs.com/xuanhun/archive/2011/06/16/2083061.html
以下是我自己的学习记录。
首先打开文档，获取body
using (WordprocessingDocument doc = WordprocessingDocument.Open(file, true)) { MainDocumentPart docPart = doc.MainDocumentPart; Body body = docPart.Document.Body; }
通过body获取1-5级目录标签
var parHasStyle = body.Descendants<Paragraph>().Where(t => t.Descendants<ParagraphStyleId>().Count() > 0 && t.Descendants<ParagraphStyleId>().All(c => c.Val == "1" || c.Val == "2" || c.Val == "3" || c.Val == "4" || c.Val == "5"));
下面是完整的获取标签，包含目录层级关系，目录的页码
/// <summary> /// 获取目录信息及页码 /// </summary> /// <returns></returns> public List<XmlMark> GetMenus() { List<XmlMark> menus = new List<XmlMark>(); Body body = _doc.MainDocumentPart.Document.Body; var pars = body.Descendants<SdtBlock>().First().Descendants<SdtContentBlock>().First().Descendants<Paragraph>(); foreach (var par in pars) { var txt = ToText(par); if (txt == "目录" || string.IsNullOrEmpty(txt)) continue; XmlMark xml = null; var hyperlink = par.Descendants<Hyperlink>().First(); if (hyperlink != null) { xml = new XmlMark(txt, hyperlink.Anchor); } else { var p = par.Descendants<FieldCode>().First(fc => fc.Text.Contains("HYPERLINK")); if (p == null) continue; var match = System.Text.RegularExpressions.Regex.Match(p.Text, "_Toc\\d+"); if (!match.Success) continue; xml = new XmlMark(txt, match.Value); } var num = System.Text.RegularExpressions.Regex.Match(txt, "(?<=-\\s)\\d+(?=\\s-)");//获取目录上的页码，格式：- 22 - if (!num.Success) continue; xml.PageIndex = Convert.ToInt32(num.Value); menus.Add(xml); } return menus; } /// <summary> /// 转成文本 /// </summary> /// <param name="p"></param> /// <returns></returns> private string ToText(Paragraph p) { return string.Join("", p.Descendants<Text>().Select(t => t.Text)); } /// <summary> /// 获取书签信息包含页码，标签的层级关系 /// </summary> /// <returns></returns> public List<XmlMark> GetMarks() { //用来匹配页码 var menus = GetMenus(); Dictionary<string, int> mark2pageindex = new Dictionary<string, int>(); foreach (var xml in menus) { mark2pageindex.Add(xml.BookmarkName, xml.PageIndex); } List<XmlMark> marks = new List<XmlMark>(); Body body = _doc.MainDocumentPart.Document.Body; var pars = body.Descendants<Paragraph>().Where(t => t.Descendants<ParagraphStyleId>().Count() > 0 && t.Descendants<ParagraphStyleId>().All(c => c.Val == "1" || c.Val == "2" || c.Val == "3" || c.Val == "4" || c.Val == "5")); XmlMark premark = null; foreach (var par in pars) { var mark = new XmlMark(par); if (string.IsNullOrEmpty(mark.BookmarkId)) continue; if (mark2pageindex.ContainsKey(mark.BookmarkName)) mark.PageIndex = mark2pageindex[mark.BookmarkName]; var parent = GetParentmark(premark, mark); if (parent == null) marks.Add(mark); else parent.AddItem(mark); premark = mark; } return marks; } /// <summary> /// 获取父标签 /// </summary> /// <param name="parent"></param> /// <param name="mark"></param> /// <returns></returns> private XmlMark GetParentmark(XmlMark parent, XmlMark mark) { if (parent == null) return null; if (mark.PStyleId == parent.PStyleId) return parent.Parent; if (mark.PStyleId.CompareTo(parent.PStyleId) > 0) return parent; else return GetParentmark(parent.Parent, mark); }
//标签数据类
public class XmlMark { public XmlMark(string name, string markName) { Name = name; BookmarkName = markName; } public XmlMark(Paragraph par) { Par = par; Name = par.InnerText; PStyleId = par.Descendants<ParagraphStyleId>().First().Val; var starts = par.Descendants<BookmarkStart>(); if (starts.Count() > 0) { BookmarkName = starts.First().Name; BookmarkId = starts.First().Id; } } public Paragraph Par { get; set; } public string Name { get; set; } public int PageIndex { get; set; } public string PStyleId { get; set; } public string BookmarkName { get; set; } public string BookmarkId { get; set; } public XmlMark Parent { get; set; } public List<XmlMark> MenuItems { get; private set; } = new List<XmlMark>(); public void AddItem(XmlMark menu) { menu.Parent = this; this.MenuItems.Add(menu); } public void RemoveItem(XmlMark menu) { this.MenuItems.Remove(menu); menu.Parent = null; } public void Clear() { MenuItems.ForEach(m => m.Parent = null); MenuItems.Clear(); } }
接下去就是添加数据：
首先是插入文本（使用只需要body.Append()就可以了）
/// <summary> /// 添加文本 /// </summary> /// <param name="txt">字符串</param> /// <param name="fontname">字体</param> /// <param name="fontSize">大小</param> /// <param name="isbold">是否加粗</param> /// <param name="horizontalcenter">水平居中</param> /// <param name="fontcolor">字体颜色</param> /// <returns></returns> public Paragraph AddText(string txt, string fontname = "宋体", int fontSize = 11, bool isbold = false, bool horizontalcenter = false, System.Drawing.Color fontcolor = default(System.Drawing.Color)) { Paragraph paragraph1 = new Paragraph(); ParagraphProperties paragraphProperties1 = new ParagraphProperties(); Justification justification1 = new Justification() { Val = JustificationValues.Center }; ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties(); RunFonts runFonts1 = new RunFonts() { Hint = FontTypeHintValues.EastAsia, Ascii = fontname, HighAnsi = fontname, EastAsia = fontname, ComplexScript = fontname }; FontSize fontSize1 = new FontSize() { Val = (fontSize * 2).ToString() }; FontSizeComplexScript fontSizeComplexScript1 = new FontSizeComplexScript() { Val = (fontSize * 2).ToString() }; Languages languages1 = new Languages() { Val = "en-US", EastAsia = "zh-CN" }; paragraphMarkRunProperties1.Append(runFonts1); if (isbold) paragraphMarkRunProperties1.Append(new Bold()); paragraphMarkRunProperties1.Append(fontSize1); paragraphMarkRunProperties1.Append(fontSizeComplexScript1); paragraphMarkRunProperties1.Append(languages1); if (horizontalcenter) paragraphProperties1.Append(justification1); paragraphProperties1.Append(paragraphMarkRunProperties1); Run run1 = new Run(); RunProperties runProperties1 = new RunProperties(); RunFonts runFonts2 = new RunFonts() { Hint = FontTypeHintValues.EastAsia, Ascii = fontname, HighAnsi = fontname, EastAsia = fontname, ComplexScript = fontname }; FontSize fontSize2 = new FontSize() { Val = (fontSize * 2).ToString() }; FontSizeComplexScript fontSizeComplexScript2 = new FontSizeComplexScript() { Val = (fontSize * 2).ToString() }; Languages languages2 = new Languages() { Val = "en-US", EastAsia = "zh-CN" }; runProperties1.Append(runFonts2); if (isbold) runProperties1.Append(new Bold()); if (fontcolor != default(System.Drawing.Color)) { var r = fontcolor.R.ToString("X"); var g = fontcolor.G.ToString("X"); var b = fontcolor.B.ToString("X"); string str = ""; if (r.Length == 1) str += "0"; str += r; if (g.Length == 1) str += "0"; str += g; if (b.Length == 1) str += "0"; str += b; runProperties1.Append(new Color() { Val = str }); } runProperties1.Append(fontSize2); runProperties1.Append(fontSizeComplexScript2); runProperties1.Append(languages2); Text text1 = new Text(); text1.Text = txt; run1.Append(runProperties1); run1.Append(text1); BookmarkStart bookmarkStart1 = new BookmarkStart() { Name = "_GoBack", Id = "0" }; BookmarkEnd bookmarkEnd1 = new BookmarkEnd() { Id = "0" }; paragraph1.Append(paragraphProperties1); paragraph1.Append(run1); paragraph1.Append(bookmarkStart1); paragraph1.Append(bookmarkEnd1); return paragraph1; }
然后插入表格的代码：（使用只需要body.Append()就可以了）
public Table AddTable(System.Data.DataTable data) { var table = new Table(); var totalwidth = data.Columns.Count * 120 * 15; var tableProperties1 = new TableProperties(); var tableStyle1 = new TableStyle() { Val = "a7" }; var tableWidth1 = new TableWidth() { Width = totalwidth.ToString(), Type = TableWidthUnitValues.Dxa }; var tableJustification1 = new TableJustification() { Val = TableRowAlignmentValues.Center }; var tableLayout1 = new TableLayout() { Type = TableLayoutValues.Fixed }; var tableLook1 = new TableLook() { Val = "04A0", FirstRow = true, LastRow = false, FirstColumn = true, LastColumn = false, NoHorizontalBand = false, NoVerticalBand = true }; tableProperties1.Append(tableStyle1); tableProperties1.Append(tableWidth1); tableProperties1.Append(tableJustification1); tableProperties1.Append(tableLayout1); tableProperties1.Append(tableLook1); var tableGrid1 = new TableGrid(); int count = data.Columns.Count; for (int i = 0; i < count; ++i) { var gridColumn1 = new GridColumn() { Width = (120 * 15).ToString() }; } table.Append(tableProperties1); table.Append(tableGrid1); foreach (System.Data.DataRow row in data.Rows) { var tableRow1 = new TableRow(); var tableRowProperties1 = new TableRowProperties(); var tableRowHeight1 = new TableRowHeight() { Val = 400U, HeightType = HeightRuleValues.AtLeast }; var tableJustification2 = new TableJustification() { Val = TableRowAlignmentValues.Center }; tableRowProperties1.Append(tableRowHeight1); tableRowProperties1.Append(tableJustification2); var tablePropertyExceptions1 = new TablePropertyExceptions(); var tableBorders2 = new TableBorders(); var topBorder2 = new TopBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; var leftBorder2 = new LeftBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; var bottomBorder2 = new BottomBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; var rightBorder2 = new RightBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; var insideHorizontalBorder2 = new InsideHorizontalBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; var insideVerticalBorder2 = new InsideVerticalBorder() { Val = BorderValues.Single, Color = "auto", Size = 4U, Space = 0U }; tableBorders2.Append(topBorder2); tableBorders2.Append(leftBorder2); tableBorders2.Append(bottomBorder2); tableBorders2.Append(rightBorder2); tableBorders2.Append(insideHorizontalBorder2); tableBorders2.Append(insideVerticalBorder2); tablePropertyExceptions1.Append(tableBorders2); tableRow1.Append(tablePropertyExceptions1); tableRow1.Append(tableRowProperties1); for (int cellindex = 0; cellindex < data.Columns.Count; ++cellindex) { var cell = row[cellindex]; if (cell == null) { continue; } var tableCell1 = new TableCell(); var tableCellProperties1 = new TableCellProperties(); var tableCellWidth1 = new TableCellWidth() { Width = (120 * 15).ToString(), Type = TableWidthUnitValues.Dxa }; var tableCellVerticalAlignment1 = new TableCellVerticalAlignment() { Val = TableVerticalAlignmentValues.Center }; tableCellProperties1.Append(tableCellWidth1); tableCellProperties1.Append(tableCellVerticalAlignment1); var paragraph1 = new Paragraph(); var paragraphProperties1 = new ParagraphProperties(); var paragraphMarkRunProperties1 = new ParagraphMarkRunProperties(); var runFonts1 = new RunFonts() { Hint = FontTypeHintValues.Default, EastAsiaTheme = ThemeFontValues.MinorEastAsia }; var verticalTextAlignment1 = new VerticalTextAlignment() { Val = VerticalPositionValues.Baseline }; var languages1 = new Languages() { Val = "en-US", EastAsia = "zh-CN" }; var justification1 = new Justification() { Val = JustificationValues.Center }; paragraphMarkRunProperties1.Append(runFonts1); paragraphMarkRunProperties1.Append(verticalTextAlignment1); paragraphMarkRunProperties1.Append(languages1); paragraphProperties1.Append(paragraphMarkRunProperties1); paragraphProperties1.Append(justification1); paragraph1.Append(paragraphProperties1); var run1 = new Run(); var runProperties1 = new RunProperties(); var runFonts2 = new RunFonts() { Hint = FontTypeHintValues.EastAsia }; var verticalTextAlignment2 = new VerticalTextAlignment() { Val = VerticalPositionValues.Baseline }; var languages2 = new Languages() { Val = "en-US", EastAsia = "zh-CN" }; runProperties1.Append(runFonts2); runProperties1.Append(verticalTextAlignment2); runProperties1.Append(languages2); var text1 = new Text(); text1.Text = cell.ToString(); run1.Append(runProperties1); run1.Append(text1); paragraph1.Append(run1); tableCell1.Append(tableCellProperties1); tableCell1.Append(paragraph1); tableRow1.Append(tableCell1); } table.Append(tableRow1); } return table; }
接下去添加图片 可以看看这两篇文章https://www.jb51.net/article/55567.htm 和 https://blog.csdn.net/renfufei/article/details/77481753/
首先图片宽高对应关系：300*300对应的图片大小为：7.935cm*7.035cm，至于如何计算可以参考下面的计算换算规则：
然而Open xml中的度量单位为EMU（全称为 English Metric Unit)，1cm =360000EMUS,所以7.935cm=7.935*360000=2857500
下面添加图片的代码：（使用只需要body.Append()就可以了）

其他补充内容：
使用Open XML SDK 2.5将图像添加到/ word / media文件夹
你必须自己创建图像的包部分.
MainDocumentPart类的AddImagePart()成员函数
始终将图像存储在/ media文件夹中.
下面的代码显示了如何将图像插入/ word / media文件夹
使用以下步骤：
>创建一个包含路径Uri设置为/ word / media的PackagePart.
>将图像数据输入包装部件.
>为图像创建PackageReleationship.
>使用PackageReleationship的ID来引用图像word文档.
我已经复制了AddImageToBody()函数的代码
