有没有办法在vb.net windows窗体系统中捕获应用程序退出事件？

Question

在C＃中，我曾经使用program.cs中的以下代码捕获应用程序退出事件。

   static void OnProcessExit(object sender, EventArgs e)
    {
        string message = "The application was closed at :" + DateTime.Now.ToString() + "."; 


    }

VB.NET中的等价物是什么？

如果数据库连接在应用程序退出事件中有任何机会打开，我想关闭它。

Answer 1

试试这个

AddHandler Application.ApplicationExit, AddressOf OnApplicationExit

Private Sub OnApplicationExit(ByVal sender As Object, ByVal e As EventArgs)
    ' When the application is exiting, write the application data to the 
    ' user file and close it.
    WriteFormDataToFile()

    Try 
        ' Ignore any errors that might occur while closing the file handle.
        userData.Close()
    Catch 
    End Try 
End Sub

双击MyProject，然后点击Application Tab，然后点击View Application Events按钮。 Shutdown有一个事件 - 当应用程序关闭时会触发。
