Web Form Designer generated code
private void btnMIME_Click(object sender, System.EventArgs e)
{
Response.ContentType = "application/vnd.ms-excel";

方法二:

{

}
else
{
Response.Clear();
Response.Buffer= true;

Response.AppendHeader("Content-Disposition","attachment;filename=FileName.xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");
//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);

Response.End();
}
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");
// 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码!!!
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

this.GridView1.RenderControl(oHtmlTextWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
