如何在C#中从控制台窗口返回焦点?

// this should do the trick....

[DllImport("user32.dll")]
public static extern bool ShowWindowAsync(HandleRef hWnd, int nCmdShow);
[DllImport("user32.dll")]
public static extern bool SetForegroundWindow(IntPtr WindowHandle);

public const int SW_RESTORE = 9;

private void FocusProcess(string procName)
{
    Process[] objProcesses = System.Diagnostics.Process.GetProcessesByName(procName);
    if (objProcesses.Length > 0)
    {
        IntPtr hWnd = IntPtr.Zero;
        hWnd = objProcesses[0].MainWindowHandle;
        ShowWindowAsync(new HandleRef(null,hWnd), SW_RESTORE);
        SetForegroundWindow(objProcesses[0].MainWindowHandle);
    }
}

要为当前正在运行的C#控制台应用程序执行此操作。。。

[DllImport("user32.dll")]
public static extern bool ShowWindowAsync(HandleRef hWnd, int nCmdShow);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr zeroOnly, string lpWindowName);
public const int SW_RESTORE = 9;
static void FocusMe()
{
    string originalTitle = Console.Title;
    string uniqueTitle = Guid.NewGuid().ToString();
    Console.Title = uniqueTitle;
    Thread.Sleep(50);
    IntPtr handle = FindWindowByCaption(IntPtr.Zero, uniqueTitle);

    Console.Title = originalTitle;

    ShowWindowAsync(new HandleRef(null, handle), SW_RESTORE);
    SetForegroundWindow(handle);
}
