How to add controls to a WinForms form?

To add controls to a WinForms form, you can follow these steps:

1. Open the WinForms project in Visual Studio and open the form where you want to add controls.
2. Find the components to be added in the toolbox, such as buttons, text boxes, etc.
3. Drag the control from the toolbox onto the form. Adjust the position and size of the control to place it in the appropriate location.
4. To set the properties of a control, you can make changes in the Properties window, such as modifying the text or color of the control.
5. To add an event handler, you can double-click on the control to generate a default event handler, or manually add an event handler by finding the event list in the property window.
