How to post updates to Twitter using Visual Basic.NET and C#

I recently created a service to post updates to the Twitter account of my website (http://twinsornot.com/).

I found some codes that does that, but using the HttpWebRequest.

I decided to make it more simple by using WebClient.

Here's the Visual Basic .NET code:

Public Sub PostTwitterUpdate(ByVal userName As String, ByVal password As String, ByVal updateMessage As String)
    Using wc As New WebClient
        wc.Credentials = New NetworkCredential(userName, password)
        ServicePointManager.Expect100Continue = False

        Dim updateMessageBytes = System.Text.Encoding.UTF8.GetBytes("status=" & updateMessage) 'Use UTF8 to get it properly encoded if you use characters like ç ã etc...

        wc.UploadData("http://twitter.com/statuses/update.xml", updateMessageBytes)
    End Using
End Sub

And here is the C# version:

public void PostTwitterUpdate(string userName, string password, string updateMessage)
{
    using (WebClient wc = new WebClient())
    {
        wc.Credentials = new NetworkCredential(userName, password);
        ServicePointManager.Expect100Continue = false;

        byte[] updateMessageBytes = System.Text.Encoding.UTF8.GetBytes("status=" + updateMessage); //Use UTF8 to get it properly encoded if you use characters like ç ã etc...

        wc.UploadData("http://twitter.com/statuses/update.xml", updateMessageBytes);
    }
}
