While uploading Zip file more than 20MB into FTP server, the Error [The underlying connection was closed: An unexpected error occurred on a receive] raised in suituation.
here i attached the code. for where the exception raise
 {ftpReq.Credentials = new NetworkCredential(userName, passWord);
                ftpReq.KeepAlive = false;
                ftpReq.Method = WebRequestMethods.Ftp.UploadFile;
                ftpReq.UseBinary = true;
                FileStream fs = fileInfo.Open(FileMode.OpenOrCreate,    FileAccess.ReadWrite, FileShare.ReadWrite);
                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, buffer.Length);
                Stream ftpstream = ftpReq.GetRequestStream();
                ftpstream.Write(buffer, 0, buffer.Length);
           **`ftpstream.Close();`****---->  the Error Appeared in the suituation while closing FTP connection .i applied solution for the problem from website .
     i have set Timeout Property of FTP. {ftpreq.Timeout=300000[5min] } above Web Request methods. In My Local Host it' allow to upload upto 50. while uploading file in  Production it allows 30 MB file to upload. if we upload more than 30 MB shows error "Server time out problem"i have tried lot of testing, but i could not fix the issue.

これ以上のファイル サイズをアップロードできない理由と、正しい解決策を提供してください。そのために私たちがしなければならないことは何ですか？

webconfigでデフォルトのアップロードサイズを変更する必要があると思います

このような

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="size in kbs" />
  </system.web>
</configuration>

デフォルトは 4096 (= 4 MB) です。
