I need to delete some certain files, then user closes program in WPF. So I tried MDSN code from here http://msdn.microsoft.com/en-us/library/system.windows.application.exit.aspx this way:
this code located here App.xml.cs
public partial class App : Application
{
void App_Exit(object sender, ExitEventArgs e)
{
MessageBox.Show("File deleted");
var systemPath = System.Environment.GetFolderPath(
Environment.SpecialFolder.CommonApplicationData);
var _directoryName1 = Path.Combine(systemPath, "RadiolocationQ");
var temp_file = Path.Combine(_directoryName1, "temp.ini");
if (File.Exists(temp1_file))
{
File.Delete(temp1_file);
}
}
}
// App.xaml
<Application x:Class="ModernUIApp1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml"
ShutdownMode="OnExplicitShutdown"
Exit="App_Exit">
<Application.Resources>
First of all it doesn't delete files, secondly this program stays in the process after I pushed exit button( this is really strange). This code don't give any errors. And finally it doesn't show MessageBox
So anything wrong here?
I think he just can`t find this function.
It's quite simple:
Add "Exit" property to the application tag
<Application x:Class="WpfApplication4.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml"
Exit="Application_Exit">
</Application>
and handle it in the "code behind"
private void Application_Exit(object sender, ExitEventArgs e)
{
// Perform tasks at application exit
}
The Exit event is fired when the application is shutting down or the Windows session is ending. It is fired after the SessionEnding event. You cannot cancel the Exit event.
