How to handle control events in WinForms?

Handling control events in WinForms typically involves the following steps:

1. When designing a form, select the control you want to handle events for, and then locate the Events tab in the properties window.
2. Select the event you want to handle, such as the Click event, in the Events tab.
3. Double-click on the blank space next to the event name, and Visual Studio will automatically create an event handling method for you and open the code editor.
4. Write specific logic code in event handling method to process events.

For example, the Click event of a button can be handled using the following steps:

1. When designing the window form, select a button control.
2. Find the Click event in the Events tab of the Properties window.
3. Double click on the empty space next to the Click event, and Visual Studio will automatically create a button’s Click event handler for you and open the code editor.
4. Write logic code in the event handling method, such as displaying a message box.

private void button1_Click(object sender, EventArgs e)
{
    MessageBox.Show("按钮被点击了！");
}

By following these steps, you can easily handle control events and implement corresponding logic in WinForms.
