I assume that you are already somewhat familiar with FtpWebRequest, as this is the usual way to access FTP in .NET.

You can attempt to list the directory and check for an error StatusCode.

try 
{  
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.microsoft.com/12345");  
    request.Method = WebRequestMethods.Ftp.ListDirectory;  
    using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())  
    {  
        // Okay.  
    }  
}  
catch (WebException ex)  
{  
    if (ex.Response != null)  
    {  
        FtpWebResponse response = (FtpWebResponse)ex.Response;  
        if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)  
        {  
            // Directory not found.  
        }  
    }  
}
