博主最近要写一个程序，需要获取windows中活动窗口的进程及程序路径

需要添加引用System.Windows.Forms

代码如下

using System;using System.Diagnostics;using System.Threading;using System.Runtime.InteropServices;using System.Windows.Forms;namespace GetActiveWindowProcess   //获取活动窗口进程信息{    class Program    {        [DllImport("User32.dll")]        public static extern IntPtr GetForegroundWindow();     //获取活动窗口句柄        [DllImport("User32.dll", CharSet = CharSet.Auto)]        public static extern int GetWindowThreadProcessId(IntPtr hwnd, out int ID);   //获取线程ID        static void Main(string[] args)        {            Thread.Sleep(3000);    //睡眠3s，用来选择活动窗口            IntPtr hWnd = GetForegroundWindow();    //获取活动窗口句柄            int calcID = 0;    //进程ID            int calcTD = 0;    //线程ID            calcTD = GetWindowThreadProcessId(hWnd, out calcID);            Process myProcess = Process.GetProcessById(calcID);            MessageBox.Show("进程名：" + myProcess.ProcessName + "\n" + "进程ID：" + calcID + "\n" + "程序路径：" + myProcess.MainModule.FileName);  //在MessageBox中显示获取的信息            Console.ReadKey();        }    }}
