c#对当前窗口进行关闭等操作

需调用API函数 需在开头引入命名空间 using System.Runtime.InteropServices; 获取当前窗口句柄:GetForegroundWindow() [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)] public static extern IntPtr GetForegroundWindow(); 返回值类型是IntPtr,即为当前获得焦点窗口的句柄 使用方法 : IntPtr myPtr=GetForegroundWindow(); 获取到该窗口句柄后,可以对该窗口进行操作.比如,关闭该窗口或在该窗口隐藏后,使其显示 [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)] public static extern int ShowWindow(IntPtr hwnd, int nCmdShow); 其中ShowWindow(IntPtr hwnd, int nCmdShow); nCmdShow的含义 0 关闭窗口 1 正常大小显示窗口 2 最小化窗口 3 最大化窗口 使用实例: ShowWindow(myPtr, 0); 获取窗口大小及位置:需要调用方法GetWindowRect(IntPtr hWnd, ref RECT lpRect) [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect); [StructLayout(LayoutKind.Sequential)] public struct RECT { public int Left; //最左坐标 public int Top; //最上坐标 public int Right; //最右坐标 public int Bottom; //最下坐标 } 示例: InPtr awin = GetForegroundWindow(); //获取当前窗口句柄 RECT rect = new RECT(); GetWindowRect(awin, ref rect); int width = rc.Right - rc.Left; //窗口的宽度 int height = rc.Bottom - rc.Top; //窗口的高度 int x = rc.Left; int y = rc.Top;
