Rotating an image in C#

Question

Is there a function or a way to do the following? I know you can use RotateFlip(RotateFlipType.WHATEVER); to rotate and flip an image. But is there a way to enter a specific rotation and it rotate to that angle? Or do you have to make some kinda matrix yourself? I was hoping there was a method you could enter like 45 degrees and it would rotate 45 degrees and so on. Thanks I hope this form does like codeproject and emails me if someone post a reply. Take care, very new to gdi+
