How to draw a rectangle in C# using a mouse

Question

Hi, I want to draw a rectangle on a form in C#. I read and found this article. Are there any samples or tutorials available ? The article was not very helpful.

Answer 1

The article you linked appears to be C++, which may explain why it didn't help you much.

If you create events for MouseDown and MouseUp, you should have the two corner points you need for a rectangle. From there, it's a matter of drawing on the form. System.Drawing.* should probably be your first stop. There are a couple of tutorials linked below:
