C# 只有一个程序实例 - 打开几个文件

Question

我做了所有示例:What is the correct way to create a single-instance application?作者:马特·戴维斯。

但是，我有一个打开文件的应用程序。我有这段代码:

    static Mutex mutex = new Mutex(true, "{MyApplicationTest}");
    [STAThread]
    static void Main(string[] args)
    {
        if (mutex.WaitOne(TimeSpan.Zero, true))
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(args.Length == 0 ? new Form1(string.Empty) : new Form1(args[0]));
            mutex.ReleaseMutex();
        }
        else
        {
            NativeMethods.PostMessage(
            (IntPtr)NativeMethods.HWND_BROADCAST,
            NativeMethods.WM_SHOWME,
            IntPtr.Zero,
            IntPtr.Zero);
        }

在程序已经运行的情况下如何打开下一个文件。第一个文件自动打开。相反，下一次点击只会在屏幕顶部出现应用程序窗口。
