DataGrid导出EXCEL中文乱码的问题。非诚勿扰！
private void Button1_Click(object sender, System.EventArgs e)
{

string filename ="haha";
ExportData(this.DataGrid1,filename);
}
public void ExportData(DataGrid ds,string attachName)  
{  
Response.Clear();  
Response.Buffer= true;  
Response.Charset="utf-8";  
   
Response.AppendHeader("Content-Disposition","attachment;" + attachName + "=.xls");  
Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");  
//Response.ContentType指定文件类型 可以为application/ms-excel || application/ms-word || application/ms-txt || application/ms-html || 或其他浏览器可直接支持文档  
Response.ContentType = "application/vnd.ms-excel";  
Response.Charset = "";  
   
//关闭 ViewState  
EnableViewState = false;  
System.IO.StringWriter tw = new System.IO.StringWriter();//将信息写入字符串  
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);//在WEB窗体页上写出一系列连续的HTML特定字符和文本。  
//此类提供ASP.NET服务器控件在将HTML内容呈现给客户端时所使用的格式化功能  
//获取control的HTML  
ds.RenderControl(hw);//将DATAGRID中的内容输出到HtmlTextWriter对象中  
// 把HTML写回浏览器  
Response.Write(tw.ToString());  
Response.End();  
} 

打开Excel就是乱码，因为是多种语言，不能GBK,应该怎么办？


------解决方案--------------------
Response.Charset="utf-7";

------解决方案--------------------

C# code

Response.AppendHeader("Content-Disposition","attachment;"  +  attachName  +  [color=#FF0000]"=.xls"[/color]);
