Leak using CopyFromScreen()
This is managed GDI+.
I've encountered a resource leak (GDI handle count increases) in the following code.
I think it's the Graphics.CopyFromScreen() method which is leaking.
I've got a tool to watch the open GDI handles of an application.
It always increases number by one when I execute this code.
Does anybody know what's going wrong here ?

private void toolButtonTest_Click(object sender, EventArgs e)
{
Rectangle screenRect = Screen.PrimaryScreen.WorkingArea;
using (Bitmap dumpBitmap = new Bitmap(screenRect.Width, screenRect.Height))
{
using (Graphics targetGraphics = Graphics.FromImage(dumpBitmap))
{
targetGraphics.CopyFromScreen(0, 0, 0, 0, new Size(dumpBitmap.Width, dumpBitmap.Height));
}
dumpBitmap.Save(@"e:\_test.png");
dumpBitmap.Dispose();
}
}

you don't need to Dispose the bitmap manually since your are creating it with "using"
