client.Credentials = new System.Net.NetworkCredential(ftpUsername, ftpPassword);
client.BaseAddress = ftpServer;

You'll need to use the FtpWebRequestclass to do that one, I think.
我想你需要使用FtpWebRequest类来做那个。
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
//If you need to use network credentials
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
//additionally, if you want to use the current user's network credentials, just use:
//System.Net.CredentialCache.DefaultNetworkCredentials
request.Method = WebRequestMethods.Ftp.DeleteFile;
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Console.WriteLine("Delete status: {0}", response.StatusDescription);
response.Close();

You should use FtpWebRequest when you need to delete files:
当您需要删除文件时，您应该使用 FtpWebRequest：
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
request.Method = WebRequestMethods.Ftp.DeleteFile;
FtpWebResponse response = (FtpWebResponse) request.GetResponse();
Console.WriteLine("Delete status: {0}",response.StatusDescription);
response.Close();

public static bool DeleteFileOnFtpServer(Uri serverUri, string ftpUsername, string ftpPassword)
{
try
{
// The serverUri parameter should use the ftp:// scheme.
// It contains the name of the server file that is to be deleted.
// Example: ftp://contoso.com/someFile.txt.
//
if (serverUri.Scheme != Uri.UriSchemeFtp)
{
return false;
}
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
request.Method = WebRequestMethods.Ftp.DeleteFile;
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
//Console.WriteLine("Delete status: {0}", response.StatusDescription);
response.Close();
return true;
}
catch (Exception ex)
{
return false;
}
}
