c# App_Startup event

Hi!
When i run the file associated with my application, i want to do something with that file, where can i get the information about that file? basically I'm looking for c# equivalent of vb.net app_startup event.

Namespace My

    ' The following events are available for MyApplication:
    ' 
    ' Startup: Raised when the application starts, before the startup form is created.
    ' Shutdown: Raised after all application forms are closed.  This event is not raised if the application terminates abnormally.
    ' UnhandledException: Raised if the application encounters an unhandled exception.
    ' StartupNextInstance: Raised when launching a single-instance application and the application is already active. 
    ' NetworkAvailabilityChanged: Raised when the network connection is connected or disconnected.

    Partial Friend Class MyApplication
        Public Sub App_Startup(ByVal sender As Object, ByVal e As ApplicationServices.StartupEventArgs) Handles Me.Startup



        End Sub
    End Class

 
End Namespace
