privatevoidForm17_Paint(objectsender,PaintEventArgse)
{
RectangleregionRect=newRectangle(20,20,100,100);
e.Graphics.DrawRectangle(Pens.Black,regionRect);
RectangleFunionRect=newRectangleF(90,30,100,100);
e.Graphics.DrawRectangle(Pens.Red,Rectangle.Round(unionRect));
RegionmyRegion=newRegion(regionRect);
//myRegion.Union(unionRect);
//myRegion.Intersect(unionRect);
//myRegion.Exclude(unionRect);
//myRegion.Complement(unionRect);
myRegion.Xor(unionRect);
SolidBrushmyBrush=newSolidBrush(Color.Blue);
e.Graphics.FillRegion(myBrush,myRegion);
}
}
}
