问题描述

我正在尝试连接到FTP服务器,因此仅一次建立了连接,而我想打开多个连接并使用线程上传多个文件.一切正常,仅当我上传单个文件时. (1比1).


连接到FTP Server时打开多个连接时出现错误.

I am trying to Connect to FTP Server, well the connection is established only once, while I want to open multiple connections and upload multiple files using threading. everything works fine Only if I upload single file. (1 by 1).


The error appears while connecting to FTP Server opening multiple connections.

protected bool login()
{
    bool connected = false;
    try
    {
         IPEndPoint ip = new IPEndPoint(Dns.Resolve(ftpAddress).AddressList[0],ftpPort); //PORT = 21
         socket.Connect(ip); //The error occurs in this statement
     }
     catch (Exception ex)
     {
         Debug.Write(ex.Message);
     }
     return connected;
}


并且出现错误"提供了无效的参数FTP服务器IP "

我用谷歌搜索,但是没有解决方案.

我很高兴了解如果打开与ftp服务器的多个连接为什么会出现错误?


and I am getting the error "An invalid argument was supplied FTP SERVER IP"

I googled but no solution helped.

I do appreciate to understand why the error appears if I open multiple connection to ftp server?
