Thread.Sleep(毫秒数);//比如Thread.Sleep(2000)即为延时2秒
需using System.Threading;

随笔5 - 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：

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：
