如何检查FTP连接?

问题描述:

有没有检查一个FTP连接(包括主机,端口,用户名和密码)的简单,快速的方法是有效的和工作?我使用C#。谢谢你。

Is there a simple, fast way to check that a FTP connection (includes host, port, username and password) is valid and working? I'm using C#. Thank you.

您可以尝试使用
System.Net.FtpWebRequest ,然后只检查 GetResponseStream 方法。

You could try using System.Net.FtpWebRequest and then just check the GetResponseStream method.

因此,像

System.Net.FtpWebRequest myFTP = new System.Net.FtpWebRequest

//Add your credentials and ports

try
{
    myFTP.GetResponseStream();
   //set some flags
}
catch ex
{
  //handle it when it is not working
}
