一个老问题，下载中文文件名文件的编码问题

[v风雪山神庙v]

用户点击导出EXCEL按钮后，出现文件保存对话框，再点击保存，这里默认的文件名是乱码
部分代码如下

Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName,Encoding.Unicode)); 
Response.ContentType = "application/vnd.ms-excel";
Response.WriteFile(fileName); 
Response.End();

若改成HttpUtility.UrlEncode(fileName,Encoding.UTF8)，可以解决中文名的问题，但是，用户在文件保存对话框上不点保存，而是点打开，会出现找不到文件的错误提示。

请问有没有一个解决方法，既可以直接打开文件，还可以保存时默认为中文文件名

Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("Excel.xls", System.Text.Encoding.GetEncoding("GB2312")));
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

// Response.ContentType = "application/x-rar-compressed";
Export("application/ms-excel", filename ); //注意文件一类型
filename//为路径
private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();

}常用这个

谢谢各位，问题解决了
是文件名过长的问题
