asp.net对word文档进行修改 对于使用word文档做模板编辑比较适用

　　最近做项目，需要多word文档进行编辑并导出一个新的word，在最初的word编辑中留下特定的字符串用来替换，然后在本地生成一个新的word文档，并且不修改服务器中的word文档，这样才能保证服务器中的文件在下次使用的时候能正常使用。

代码：

 　　　　/// <summary>
        /// 读取出word文档中的内容后对word文档进行修改并保存在本地
        /// </summary>
　　　   /// <param name="jtmodel">实体类（在数据库中读取出来的数据）</param>
        /// <param name="pathfile">替换后的字符</param>
        private void ReadWord(Jtmodle jtmodel, String pathfile)
        {
            Microsoft.Office.Interop.Word.Document oWordDoc = null;
            Microsoft.Office.Interop.Word.ApplicationClass oWordApp = null;
            object missing = System.Reflection.Missing.Value;
            try
            {
                object fileName =  System.Web.HttpContext.Current.Server.MapPath(pathfile).ToString();
                object readOnly = false;
                object isVisible = true;      
                oWordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
                oWordDoc = oWordApp.Documents.Open(ref fileName, ref missing, ref readOnly,
                                     ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
                                     ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing);
                #region 字符替换
                oWordApp = Replce("{htmc}", jtmodel.htmc.ToString(), oWordApp);
                oWordApp = Replce("{htbh}", jtmodel.htbh.ToString(), oWordApp);
                oWordApp = Replce("{qydd}", jtmodel.qydd.ToString(), oWordApp);
                oWordApp = Replce("{qyrq}", jtmodel.qyrq.ToString(), oWordApp);
                oWordApp = Replce("{sxrq}", jtmodel.sxrq.ToString(), oWordApp);
                oWordApp = Replce("{fkqx}", jtmodel.fkqx.ToString(), oWordApp);
                oWordApp = Replce("{jfqx}", jtmodel.jfqx.ToString(), oWordApp);#endregion

                #region 保存文件到客户端
                string filePath = @"d:\WordDown\";
                if (!Directory.Exists(filePath))
                {
                    Directory.CreateDirectory(filePath);
                }
                if (!System.IO.File.Exists(@"d:\WordDown\" + jtmodel.name.Trim() + ".doc"))
                {
                    oWordDoc.SaveAs(@"d:\WordDown\" + jtmodel.name.Trim() + ".doc");
                    ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", @"<script>alert('合同文档生成成功，已保存在本地磁盘D:\WordDown\" + jtmodel.name.Trim() + ".doc！');</script>");
                }
                else
                {
                    ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", @"<script>alert('该合同文档已经存在本地磁盘D:\WordDown\" + jtmodel.name.Trim() + ".doc，生成失败！');</script>");
                }
                oWordApp.NormalTemplate.Saved = true;
                oWordDoc.Close(ref missing, ref missing, ref missing);
                oWordApp.Application.Quit(ref missing, ref missing, ref missing);                
                #endregion
            }
            catch 
            {
                oWordDoc.Close(ref missing, ref missing, ref missing);
                oWordApp.Application.Quit(ref missing, ref missing, ref missing);
            }
        }
        /// <summary>
        /// 替换word中的字符串
        /// </summary>

        /// <param name="oWordApp"></param>
        private Microsoft.Office.Interop.Word.ApplicationClass Replce(string oldstr, string newstr, Microsoft.Office.Interop.Word.ApplicationClass oWordApp)
        {
            object missing = System.Reflection.Missing.Value;
            oWordApp.Selection.Find.ClearFormatting();
            oWordApp.Selection.Find.Replacement.ClearFormatting();
            oWordApp.Selection.Find.Text = oldstr;
            oWordApp.Selection.Find.Replacement.Text = newstr;
            object objReplace = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;
            oWordApp.Selection.Find.Execute(ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref objReplace, ref missing, ref missing, ref missing, ref missing);
            return oWordApp;
        }

原本不打算用替换字符串的方式编辑word，在网上看到还有可以在word中添加标签的然后对word文档进行编辑，但是苦于不知道怎么给word文档插入标签，只好适用替换字符串的方法来实现功能了
