代码如下：
private void Button2_Click(object sender, System.EventArgs e)//////导出表格按钮
{
string filename = "ItemStat.xls";
this.DGProjectWork.AllowSorting = false;
this.DGProjectWork.AllowPaging = false;
this.DGPProjectWorkDataBind();
this.ExportExcelFromDataGrid( filename , this.DGProjectWork );
}

//导出表格函数
private void ExportExcelFromDataGrid( string filename , System.Web.UI.WebControls.DataGrid ToExcelGrid )
{
Response.Clear();
Response.Buffer=true;
Response.Charset="utf-8";
Response.AppendHeader("Content-Disposition","attachment;filename="+Server.UrlEncode ( filename ) );
Response.ContentEncoding=System.Text.Encoding.Default;//设置输出流为简体中文
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
this.EnableViewState = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
ToExcelGrid.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
}

我也遇到这样的问题。改称gb2312和utf-8都不行。不知道是什么问题呢？
