DataGrid输出文件的几种方法

从DataGrid输出文件到Excel、Word和Text文件使用这样输出还是很高效的。

1、输出到Excel：

            Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
            Response.Charset = "";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/vnd.xls";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
            myDataGrid.RenderControl(htmlWrite);
            Response.Write(stringWrite.ToString());
            Response.End();

2、输出到Word文档

            Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=FileName.doc");
            Response.Charset = "";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/vnd.word";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
            myDataGrid.RenderControl(htmlWrite);
            Response.Write(stringWrite.ToString());
            Response.End();

3、输出到文本文件

            Database db = DatabaseFactory.CreateDatabase(); 
            DBCommandWrapper selectCommandWrapper = db.GetStoredProcCommandWrapper("sp_GetLatestArticles"); 
            
            DataSet ds = db.ExecuteDataSet(selectCommandWrapper); 

            StringBuilder str = new StringBuilder(); 

            for(int i=0;i<=ds.Tables[0].Rows.Count - 1; i++) 
            {
                for(int j=0;j<=ds.Tables[0].Columns.Count - 1; j++) 
                {
                    str.Append(ds.Tables[0].Rows[i][j].ToString()); 
                }
                str.Append("<BR>");
            }

            Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=FileName.txt");
            Response.Charset = "";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/vnd.text";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
            Response.Write(str.ToString());
            Response.End();
