This is not supported by the component itself, but can be easily implemented. The following method should do what you need. It takes two arguments - an instance of Ftp object (connected and authenticated) and the path:
public static void CreatePath(Ftp ftp, string path)
{
string[] parts = path.Trim('/').Split('/');
if (parts.Length == 0)
throw new ArgumentException("Invalid path.", "path");
if (path.StartsWith("/"))
path = "/";
else
path = "";
string current = ftp.GetCurrentDirectory();
for (int i = 0; i < parts.Length; i++)
{
path += parts[i];
ftp.SendCommand("CWD " + path);
FtpResponse response = ftp.ReadResponse();
ftp.ChangeDirectory(current);
if (response.Group == 5)
ftp.CreateDirectory(path);
path += "/";
}
}
If you prefer VB.NET, please let me know.
