Question

I would like to catch all unhandled exceptions in my UI app in C#, so that I can log them, send them by mail and restart the app.

How can I simply get this done? I tried:

try
{
 Application.EnableVisualStyles();
 Application.SetCompatibleTextRenderingDefault(false);
 Application.Run(new MainDlg());
}
catch (Exception e)
{
 Logger.Log(e);
 Logger.PostLog();
  System.Diagnostics.Process.Start("App.exe");
}

But it lets some exceptions through.

You can put this code in your Program.cs:

    static void Application_ThreadException(object sender,
        ThreadExceptionEventArgs e) //Generic error handler
    {
        MyApp.LogException(e.Exception); //Log exception

        BugReport frmBugReport = new BugReport();
        frmBugReport.Error = e.Exception;
        frmBugReport.ShowDialog();

        Environment.Exit(0);
    }

I’m showing an error report dialog in my app. You can chage Environment.Exit(0) with Application.Restart() (As I remember).
