Is there a way to show part of one form on another form?

问题

I have a form. All I want to do is display a section of that form on another form. I don't want it to be functional or anything. I basically just want it to be a picture. Is that possible, and if so, how?

Like

display = new display(form, new rectangle(X1, X2, Y1, Y2));

Is that a possibility?

回答1:

Yes you can do:

Bitmap bmp = new Bitmap(myWidth, myHeight);
myForm.DrawToBitmap(bmp, new Rectangle(x, y, bmp.Width, bmp.Height));

And then pass this bitmap to the other form.
