C# 操作word文档（插入文字/表格）

主要思路：在word文档中需要插入数据的地方添加书签，然后通过获取word文档中的书签添加文字/表格

引用包：Microsoft.Office.Interop.Word

Microsoft.Office.Interop.Word.Application appWord = new Microsoft.Office.Interop.Word.Application();
            Microsoft.Office.Interop.Word.Document doc = new Microsoft.Office.Interop.Word.Document();
            object miss = System.Reflection.Missing.Value;

            DataTable dt_purCode = (DataTable)dataGridView1.DataSource; //需要插入word文档的表格数据

            string appPath = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
            //获取模板路径
            object templatePath = appPath + "Template\\Report - 副本.docx";
            Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application();
            object objDocType = Microsoft.Office.Interop.Word.WdDocumentType.wdTypeDocument;
            object objfalse = false;
            object objtrue = true;
            doc = (Microsoft.Office.Interop.Word.Document)appWord.Documents.Add(ref templatePath, ref objfalse, ref objDocType, ref objtrue);
        try{
             //获取模板中所有的书签
             Microsoft.Office.Interop.Word.Bookmarks odf = doc.Bookmarks;
             //在word文档 name 书签位置插入"张三"
             odf.get_Item("name").Range.Text = "张三";

             //在word文档 item书签位置插入表格数据
            Microsoft.Office.Interop.Word.Table dtWord = doc.Tables.Add(odf.get_Item("item").Range, dt_purCode.Rows.Count, dt_purCode.Columns.Count);
            dtWord.Borders.InsideLineStyle = Microsoft.Office.Interop.Word.WdLineStyle.wdLineStyleDot;
            dtWord.Borders.OutsideLineStyle = Microsoft.Office.Interop.Word.WdLineStyle.wdLineStyleDot;
            
            //循环往表格里赋值
            for (int i = 1; i <= dt_purCode.Rows.Count; i++)
            {
                for (int j = 1; j <= dt_purCode.Columns.Count; j++)
                {

                    dtWord.Rows[i].Cells[j].Range.Text = dt_purCode.Rows[i - 1][j - 1].ToString();

                    dtWord.Rows[i].Cells[j].Range.Font.Size = 10;  //设置表格字体 10

//如果表格字段包含箭头  设置字体颜色为红色
                    if (dt_purCode.Rows[i - 1][j - 1].ToString().Contains("↓") || dt_purCode.Rows[i - 1][j - 1].ToString().Contains("↑"))
                    {

                        dtWord.Rows[i].Cells[j].Range.Font.TextColor.RGB = (int)Microsoft.Office.Interop.Word.WdColor.wdColorRed; 
                    }
                }
            }
                

            }
            catch
            {
                throw;
            }
            finally
            {
                doc.Close();
                application.Quit();
            }
