System.IO.FileInfo file = new System.IO.FileInfo(fileName);
Response.Clear();
Response.AddHeader("Content-Type", "application/octet-stream");
Response.Charset = "utf-8";
Response.AddHeader("Content-Disposition", "attachment;filename="+System.Web.HttpUtility.UrlEncode(file.Name,System.Text.Encoding.UTF8));
Response.AddHeader("Content-Length", file.Length.ToString());
Response.WriteFile(file.FullName);
Response.Flush(); 
Response.Clear();
Response.End();
}

Answer 2

Response.Charset = "utf-8";
Response.AddHeader("Content-Disposition", "attachment;filename="+System.Web.HttpUtility.UrlEncode(file.Name,System.Text.Encoding.UTF8));这里是编码

Answer 3

filename="+System.Web.HttpUtility.UrlEncode(file.Name,System.Text.Encoding.UTF8));
此处的 filename 就是文件下载时 默认的下载文件名称。
