C# FTP Library

这个库基于C＃和.Net框架，它很好的包装了WININET.DLL的FTP功能，建立了一种有效的与FTP服务器交互的方式。

示例代码：

using (FtpConnection ftp = new FtpConnection("ftpserver", "username", "password"))
{
	
	ftp.Open(); /* Open the FTP connection */
	ftp.Login(); /* Login using previously provided credentials */

	if (ftp.DirectoryExists("/incoming")) /* check that a directory exists */
		ftp.SetCurrentDirectory("/incoming"); /* change current directory */

	if (ftp.FileExists("/incoming/file.txt"))  /* check that a file exists */
		ftp.GetFile("/incoming/file.txt", false); /* download /incoming/file.txt as file.txt to current executing directory, overwrite if it exists */

	//do some processing

	try
	{
		ftp.SetCurrentDirectory("/outgoing");
		ftp.PutFile(@"c:\localfile.txt", "file.txt"); /* upload c:\localfile.txt to the current ftp directory as file.txt */
	}
	catch (FtpException e)
	{
		Console.WriteLine(String.Format("FTP Error: {0} {1}", e.ErrorCode, e.Message));
	}

	foreach(var dir in ftp.GetDirectories("/incoming/processed"))
	{
		Console.WriteLine(dir.Name);
		Console.WriteLine(dir.CreationTime);
		foreach (var file in dir.GetFiles())
		{
			Console.WriteLine(file.Name);
			Console.WriteLine(file.LastAccessTime);
		}
	}
}
