Examples

The following example shows how to use the OnExited method in a derived class.

using System;
using System.Diagnostics;

class MyProcess : Process
{
    public void Stop()
    {
        this.CloseMainWindow();
        this.Close();
        OnExited();
    }
}
class StartNotePad
{

    public static void Main(string[] args)
    {
        MyProcess p = new MyProcess();
        p.StartInfo.FileName = "notepad.exe";
        p.EnableRaisingEvents = true;
        p.Exited += new EventHandler(myProcess_HasExited);
        p.Start();
        p.WaitForInputIdle();
        p.Stop();
    }
    private static void myProcess_HasExited(object sender, System.EventArgs e)
    {
        Console.WriteLine("Process has exited.");
    }
}

Imports System.Diagnostics


Class MyProcess
    Inherits Process
    
    Public Sub [Stop]() 
        Me.CloseMainWindow()
        Me.Close()
        OnExited()
    
    End Sub
End Class

Class StartNotePad
    
    
    Public Shared Sub Main(ByVal args() As String) 
        Dim p As New MyProcess()
        p.StartInfo.FileName = "notepad.exe"
        p.EnableRaisingEvents = True
        AddHandler p.Exited, AddressOf myProcess_HasExited
        p.Start()
        p.WaitForInputIdle()
        p.Stop()
    
    End Sub
    
    Private Shared Sub myProcess_HasExited(ByVal sender As Object, ByVal e As System.EventArgs) 
        Console.WriteLine("Process has exited.")
    
    End Sub
End Class

Remarks

OnExited is the API method that raises the Exited event. Calling OnExited causes the Exited event to occur and is the only way to raise the event using the Process component. OnExited is primarily used when deriving classes from the component.

As an alternative to OnExited, you can write your own event handler. You create your own event handler delegate and your own event-handling method.

Note

If you are using the Visual Studio environment, an event handler delegate (AddOnExited) and an event-handling method (Process1_Exited) are created for you when you drag a Process component onto a form and double-click the icon. The code you create to run when the Exited event occurs is entered into the Process1_Exited procedure. You do not need to create the OnExited member, because it is implemented for you.

Raising an event invokes the event handler through a delegate. For an overview, see Handling and Raising Events.
