Convert a phrase to VB

Hi;
The tutorial is srtight forward but I'm a VB.NET programmer.
Can anyone Covert below statment in upload.aspx.cs to VB or assistant me:

using(System.Drawing.Image image =
System.Drawing.Image.FromStream(file.InputStream))
using(Bitmap bitmap = new Bitmap(image, ThumbnailWidth, ThumbnailHeight))
{
bitmap.Save(MapPath("uploaded_images/t__" + fileName), image.RawFormat);
AppendMessage("<span style=\"color:green;\">Thumbnail" +
" created...</span><br><br>");
}

Dim image As System.Drawing.Image = Nothing
Dim bitmap As Bitmap = Nothing

Try
	image = System.Drawing.Image.FromStream(file.InputStream))
	bitmap = New Bitmap(image, ThumbnailWidth,  ThumbnailHeight)

	bitmap.Save(MapPath("uploaded_images/t__" &  fileName), image.RawFormat)
	AppendMessage("<span style=""color:green;"">Thumbnail" & _
		" created...</span><br><br>")
Finally
	If image <> Nothing Then
		image.Dispose()
	End If

	If bitmap <> Nothing Then
		bitmap.Dispose()
	End If
End Try
