帮忙看一下导出文件为什么不能下载

[小菲1215]

public void ExportToExcel(string FileName, string[] ColumnHeader_Name, DataTable ExportDT)
{
FileName = HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8);
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename="+FileName);
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
string colHeaders = "", ls_item = "";
foreach (string ColumnHeaderString in ColumnHeader_Name)
{
colHeaders += ColumnHeaderString + "\t";
}
colHeaders += "\n";
HttpContext.Current.Response.Write(colHeaders);
foreach (DataRow RowView in ExportDT.Rows)
{
for(int j=0;j<ColumnHeader_Name.Length;j++)
ls_item += RowView[j].ToString().Trim() + "\t";
ls_item += "\n";
}
HttpContext.Current.Response.Write(ls_item);
HttpContext.Current.Response.End();
}
在有些电脑是能正常下载，有些电脑点了没有反映，不停在获取文件信息这儿停住

安全机制。IE设置有关系吧，。

iis的mime类型里新增类型 ，后缀名xls，描述application/vnd.ms-excel
