UploadProgressChanged event not being called properly-CodePudding

With the following code:

using (var uploadClient = new WebClient()) {
    uploadClient.Credentials = new NetworkCredential(util.ftp_user, util.ftp_pass);
    uploadClient.UploadProgressChanged  = new UploadProgressChangedEventHandler(UploadProgressCallback);
    uploadClient.UploadFileCompleted  = new UploadFileCompletedEventHandler(UploadProgressCompleted);
    uploadClient.UploadFileAsync(new Uri(util.URIstr   picName), "POST", filenamewAdress);
    }

public void UploadProgressCallback(object sender, UploadProgressChangedEventArgs e) {
    Console.WriteLine("UploadProgressCalledback");
}

public void UploadProgressCompleted(object sender, UploadFileCompletedEventArgs e) {
    Console.WriteLine("Upload File Completed");
}

The UploadProgressChangedEventHandler is not being called, but UploadFileCompletedEventHandler is being called and the file is being uploaded correctly. What am I missing?

Change

uploadClient.UploadFileAsync(new Uri(util.URIstr   picName), "POST", filenamewAdress);

uploadClient.UploadFileAsync(new Uri(util.URIstr   picName), "STOR", filenamewAdress);

My problem is Solved. I used "STOR" instead of "POST" and now UploadProgressChangedEventHandler is worked correctly.
