WPF 启动带参数

两个项目WpfStartupWithArgsDemo（WPF项目）和WpfStartupWithArgsDemo.Console（控制台项目）
启动控制台项目WpfStartupWithArgsDemo.Console，在代码中启动WpfStartupWithArgsDemo，并传递参数

string exePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "..\\..\\..\\WpfStartupWithArgsDemo\\bin\\Debug\\WpfStartupWithArgsDemo.exe");
if (File.Exists(exePath))
{
    ProcessStartInfo startInfo = new ProcessStartInfo(exePath, string.Format("{0} {1} {2}", "FirstArg", exePath, 3))
    {
        CreateNoWindow = true,
        UseShellExecute = false
    };

    Process.Start(startInfo);

    Environment.Exit(0);
}

在WpfStartupWithArgsDemo的Startup事件中接收参数

<Application x:Class="WpfStartupWithArgsDemo.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfStartupWithArgsDemo"
             Startup="App_OnStartup">
</Application>

private void App_OnStartup(object sender, StartupEventArgs e)
{
    ObservableCollection<string> data = new ObservableCollection<string>();
    for (int i = 0; i < e.Args.Length; i++)
    {
        data.Add(e.Args[i]);
        Console.WriteLine(e.Args[i]);
    }
}
