C＃使用命令行参数启动app

Question

I have a small app( C# WPF ) that starts automatically with system, but i want that main window of my program will not shown when it starts from autorun(with command-line parameter autorun ).

I written this code:

    protected override void OnStartup(StartupEventArgs e)
    {

        if (e.Args.Length == 0) 
            this.Run(new MainWindow());

        base.OnStartup(e);

    }

But it didn't work... So how i can check existence of my autorun parameter from App.xaml.cs and prevent opening MainWindow ?

Thanks.

Find StartupUri attribute at the top of your App.xaml file and remove it:

override the OnStartup as below

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);

    if (e.Args.Length == 0)
    {
        // no argument 
        // do stuff 
    }
    else
    {
        // with arguments
        // do stuff 
    }
    this.Shutdown();
}
