C# 控制台窗口的显示与隐藏

1. 定义一个Consolse帮助类，如下：

/// <summary>
/// 控制台帮助类
/// </summary>
public static class ConsoleHelper
{
    /// <summary>
    /// 获取窗口句柄
    /// </summary>
    /// <param name="lpClassName"></param>
    /// <param name="lpWindowName"></param>
    /// <returns></returns>
    [DllImport("user32.dll", SetLastError = true)]
    private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    /// <summary>
    /// 设置窗体的显示与隐藏
    /// </summary>
    /// <param name="hWnd"></param>
    /// <param name="nCmdShow"></param>
    /// <returns></returns>
    [DllImport("user32.dll", SetLastError = true)]
    private static extern bool ShowWindow(IntPtr hWnd, uint nCmdShow);

    /// <summary>
    /// 隐藏控制台
    /// </summary>
    /// <param name="ConsoleTitle">控制台标题(可为空,为空则取默认值)</param>
    public static void hideConsole(string ConsoleTitle = "")
    {
        ConsoleTitle = String.IsNullOrEmpty(ConsoleTitle) ? Console.Title : ConsoleTitle;
        IntPtr hWnd = FindWindow("ConsoleWindowClass", ConsoleTitle);
        if (hWnd != IntPtr.Zero)
        {
            ShowWindow(hWnd, 0);
        }
    }

    /// <summary>
    /// 显示控制台
    /// </summary>
    /// <param name="ConsoleTitle">控制台标题(可为空,为空则去默认值)</param>
    public static void showConsole(string ConsoleTitle = "")
    {
        ConsoleTitle = String.IsNullOrEmpty(ConsoleTitle) ? Console.Title : ConsoleTitle;
        IntPtr hWnd = FindWindow("ConsoleWindowClass", ConsoleTitle);
        if (hWnd != IntPtr.Zero)
        {
            ShowWindow(hWnd, 1);
        }
    }
}

2. 程序中调用，如下：

ConsoleHelper.hideConsole();

3. 注意：如果程序是只能启动一个，则可以用上面的方法控制控制台的显示与隐藏；否则需要在初始化时对控制台的标题赋值，如下：

Console.Title = Guid.NewGuid().ToString();
