Application.ThreadExit Application.ThreadExit Application.ThreadExit Application.ThreadExit Event

Definition

Occurs when a thread is about to shut down. When the main thread for an application is about to be shut down, this event is raised first, followed by an ApplicationExit event.

public:
 static event EventHandler ^ ThreadExit;
public static event EventHandler ThreadExit;
member this.ThreadExit : EventHandler 
Public Shared Custom Event ThreadExit As EventHandler 

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ThreadExit event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a Windows Forms and ensure that the event handler is associated with the ThreadExit event.

private void Application_ThreadExit(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Application.ThreadExit event.");

}
Private Sub Application_ThreadExit(ByVal sender As Object, ByVal e As EventArgs) 

    MessageBox.Show("You are in the Application.ThreadExit event.")

End Sub

Remarks

You must attach the event handlers to the ThreadExit event to perform any unhandled, required tasks before the thread stops running. Close files opened by this thread, or dispose of objects that the garbage collector did not reclaim.

Caution

Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
