.net core 导出word文档
版权声明:本文为博主原创文章,未经博主允许不得转载。
一个项目,要做一个从数据库读取数据,然后导出到word,因为涉及到后台数据库的读取,决定用npoi来导出word。
NPOI源码地址:http://npoi.codeplex.com/
NPOI 2.0 api文档: http://www.npoi.info/npoi2tutorial
因为npoi操作word的文章比较少,在由于版本不同,相关的函数可能不一样,这个就需要大家自己去慢慢的探索了。
例如:作者的api文档中
c.字体加粗
r1.SetBold(true);
实际我在调用时,调用的接口是 r1c1.IsBold = 12;
我使用的版本是:NPOI v2.2.0.0
需要引用的命名空间如下
using NPOI.XWPF.UserModel;
using NPOI.OpenXmlFormats.Wordprocessing;
最终效果图如下:
关键代码如下:
- /// <summary>
- /// 新增
- /// </summary>
- /// <param name="sender"></param>
- /// <param name="e"></param>
- protected void btnPrint_Click(object sender, EventArgs e)
- {
- //创建document对象
- XWPFDocument doc = new XWPFDocument();
- //创建段落对象
- XWPFParagraph p1 = doc.CreateParagraph();
- p1.Alignment = ParagraphAlignment.CENTER;//字体居中
- //创建run对象
- //本节提到的所有样式都是基于XWPFRun的,
- //你可以把XWPFRun理解成一小段文字的描述对象,
- //这也是Word文档的特征,即文本描述性文档。

设置table的宽度,以及没列的宽度代码如下:
- XWPFTable tableTop = doc.CreateTable(6, 5);
- tableTop.Width = 1000 * 5;/* 设置table宽度,必须设置width,SetColumnWidth才有效 */
- tableTop.SetColumnWidth(0, 1300);/* 设置第一列宽 */
- tableTop.SetColumnWidth(1, 500);/* 设置第二列宽 */
- tableTop.SetColumnWidth(2, 1000);/* 设置列宽 */
- tableTop.SetColumnWidth(3, 500);/* 设置列宽 */
- tableTop.SetColumnWidth(4, 1700);/* 设置列宽 */
和并列以及设置列的高度:
tableTop.GetRow(0).MergeCells(1, 4);/* 合并列 */
XWPFRun r1c1 = pCell.CreateRun();
r1c1.SetText(setText);
r1c1.FontSize = 12;
r1c1.SetFontFamily("华文楷体", FontCharRange.None);//设置雅黑字体
r1c1.SetTextPosition(textPos);//设置高度
NPOI已出现一段时间了,目前版本2.0 Beta 2 [v2.0.5],网上关于NPOI操作xlsx文章较多,而关于docx的几乎没有,尽管NPOI对于Word还不稳定,经过一阵捣鼓后终于实现了表的简单操作:创建表、创建行、创建单元,单元行和列的合并。
