Bitmap masking the .NET way

[Guest]

Hello there,
Does anyone know how to to Bitmap masking in .NET,
In c++ i used,
CreateCompatibleDC
GetBitmap

Then on the bitmap and the bitmap mask i called.
{SelectBitmap
StretchBlt}

No I gather i can do this
Bitmap offScreenBmp;
Graphics offScreenDC;
offScreenBmp = new Bitmap(this.Width, this.Height);
offScreenDC = Graphics.FromImage(offScreenBmp);

but how do i load the second bitmap mask somehow to make a transparent bitmap?

thanks in advance
