Hi, I am writing a Windows Form application.
When clicking a button (button A) on Main form (form A), I create a New form (form B) from Main form (form A).

The question is:
How can form A know form B is closed, so that form A can automatically do some process?

推荐答案

让表单A订阅FormB的FormClosing 事件:

示例:

Have Form A subscribe to FormClosing event of FormB:

Example:

public partial class FormA : Form
{
    FormB b;
    public FormA()
    {
        InitializeComponent();
        b = new FormB();
        b.FormClosed += new FormClosedEventHandler(b_FormClosed);
        b.Show();
    }
    void b_FormClosed(object sender, FormClosedEventArgs e)
    {
        MessageBox.Show("Form B Has now closed");
    }
}

是的，如果它符合您的要求，则可以使用上面的方法，但是如果表单A中没有创建表单B，则可以使用自定义事件来捕获B形式的close方法.

yes you can use the above method if it matches to your requirement , but if the form B is not created with in the form A you can use custom event to catch the B forms close method .
