asp.net後臺下載文件（解決中文亂碼）

 你是否在asp.net開發中遇到過下載文件時亂碼的現象，也許這個代碼不是最好的，但是它能幫你下載文件並且解決中文亂碼的問題

private void DownLoadFile(string fileName)

    {  
        string filePath = Server.MapPath(".") + "\\" + fileName;
        if (File.Exists(filePath))
        {
            FileInfo file = new FileInfo(filePath);
            Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); //解決中文亂碼
            Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name)); //解決中文文件名亂碼    
            Response.AddHeader("Content-length", file.Length.ToString());
            Response.ContentType = "appliction/octet-stream";
            Response.WriteFile(file.FullName);
            Response.End();
        }
