Response.Clear();

//Response.Charset = "GB2312"; //设置了类型为中文防止乱码的出现
string strFileName = String.Empty;// DateTime.Now.ToString("yyyy-MM-dd");

//strFileName = HttpUtility.UrlEncode(strFileName);
//如果直接对文件名Encode则文件名会超长，所以上面代码注释掉用下面代码
strFileName = HttpUtility.UrlEncode("FW统计报表");

Response.AppendHeader("Content-Disposition", "attachment;filename=" + strFileName + ".xls"); //定义输出文件和文件名
// 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。
