C#使用Spire.Doc Word for .Net读写Word

以前对Excel或Word文档操作都使用微软的COM组件Microsoft Word 15.0 object library。

但是这种方式必须要求服务器上安装Office，而且会出现读写操作完成后未成功释放资源的情况。

还有使用NPOI的方式，可以在没有安装Office的情况下对Word或Excel文档进行读写操作，但是面对复杂的需求，还是显得无能为力。

于是出现了一些其他的API库，如Spire.Doc和Aspose，不但可以很好地读写操作Office文档，而且可以轻松实现PDF等文档格式的转换。

Spire.Doc支持JAVA和C#开发语言。我们可以从官网下载到。

Document document = new Document();
Section section = document.AddSection();
ShowProgressBar(); //显示进度条
for (int i = 0; i < dsSpInfo.Tables[0].Rows.Count; i++)
{
       GenerateWord(document,section, dsSpInfo.Tables[0], dsQiandi.Tables[0], dsBaocun.Tables[0],i); //生成Word文档
}
section.AddColumn(550f, 50f);  //添加分栏，参数为分栏宽度
section.AddColumn(550f, 50f);
section.MakeColumnsSameWidth();
string s = Guid.NewGuid().ToString("N") + ".docx";
document.SaveToFile(@"temp\" + s, FileFormat.Docx);
document.Close();
System.Diagnostics.Process.Start(@"temp\" + s);

private void GenerateWord(Document document,Section section,DataTable dtSpInfo, DataTable dtQiandi, DataTable dtBaocun,int index)
{

      Paragraph pFamily = section.AddParagraph();   //添加段落
      AddTextRange(section, pFamily, cfamily, 14, true, "黑体", Spire.Doc.Documents.HorizontalAlignment.Center);
       AddTextRange(section, pFamily, family, 14, true, "宋体", Spire.Doc.Documents.HorizontalAlignment.Center);

       Paragraph paragraph = section.AddParagraph();
       AddTextRange(section, paragraph, cGenus, 12, true, "黑体", Spire.Doc.Documents.HorizontalAlignment.Left);
      AddTextRange(section, paragraph, genus, 12, true, "Times New Roman", Spire.Doc.Documents.HorizontalAlignment.Left);

      DataRow[] drQiandi = dtQiandi.Select("SPID='" + spid + "'"); //获取表格数据
      if (drQiandi.Length > 0) 
      {
          String[] headerQiandi = { "保存地点", "种质份数", "个体数量", "引种方式", "来源地", "生长状况" };   //表头字段
          string[][] arrQiandiData = new string[drQiandi.Length][];
          for (int i = 0; i < drQiandi.Length; i++)
          {
               arrQiandiData[i] = new string[] { drQiandi[i]["保存地点"].ToString(), drQiandi[i]["种质份数"].ToString(), drQiandi[i]["个体数量"].ToString(), drQiandi[i]["引种方式"].ToString(), drQiandi[i]["来源地"].ToString(), drQiandi[i]["生长状况"].ToString() };
          }
         Table tableQiandi = section.AddTable();  //新建表格
         tableQiandi.ResetCells(arrQiandiData.Length + 1, headerQiandi.Length);
         tableQiandi.TableFormat.Borders.BorderType = Spire.Doc.Documents.BorderStyle.Single;

        TableRow rowQiandi = tableQiandi.Rows[0];  //添加行
        rowQiandi.IsHeader = true;  //设为表头
        rowQiandi.Height = 16;
        rowQiandi.HeightType = TableRowHeightType.Auto;
         for (int i = 0; i < headerQiandi.Length; i++) //生成表头
         {
              rowQiandi.Cells[i].Width = 50;
              rowQiandi.Cells[i].CellFormat.VerticalAlignment = VerticalAlignment.Middle;

              AddTextRange(section, p, headerQiandi[i], 9, true, "黑体", Spire.Doc.Documents.HorizontalAlignment.Center);
          }

         for (int r = 0; r < arrQiandiData.Length; r++) //生成表体
         {
               TableRow dataRow = tableQiandi.Rows[r + 1];
               dataRow.RowFormat.BackColor = Color.Empty;
               for (int c = 0; c < arrQiandiData[r].Length; c++)
               {
                  dataRow.Cells[c].Width = 50;
                  dataRow.Cells[c].CellFormat.VerticalAlignment = VerticalAlignment.Middle;

                   tr.CharacterFormat.FontSize = 8;
                 }
            }
       }
}

private void AddTextRange(Section section, Paragraph pragraph, string word, float fontSize, bool isBold, string fontName, Spire.Doc.Documents.HorizontalAlignment alignType)

      TextRange textRange = pragraph.AppendText(word);

需要注意的是，Spire.Doc是收费软件，如果超过了免费版生成表格的数量（好像是25个），就要收取费用。否则会在生成的文档的第一页上方中添加广告。
