C#能不能实现发送ctrl+s这样的组合键盘命令

Question

做一个程序，目的是获取键盘的操作然后再自动发送ctrl+s命令即保存
假如当前是word应用程序，我运行C#的应用程序则word就会执行了ctrl+s命令
谢谢大家

Answer 1

貌似在KEYPRESS的参数E的KEYCODE还是KEYVALUE属性可以区分出来吧

谢谢，我正在找，到是之前有个人教了我下面的代码是捕获鼠标的，你们看下
using System;
using System.Threading;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace MouseControl1
{
    class MouseControl
    {
        /// <summary>
        /// 鼠标控制参数
        /// </summary>
        const int MOUSEEVENTF_LEFTDOWN = 0x2;
        const int MOUSEEVENTF_LEFTUP = 0x4;
        const int MOUSEEVENTF_MIDDLEDOWN = 0x20;
        const int MOUSEEVENTF_MIDDLEUP = 0x40;
        const int MOUSEEVENTF_MOVE = 0x1;
        const int MOUSEEVENTF_ABSOLUTE = 0x8000;
        const int MOUSEEVENTF_RIGHTDOWN = 0x8;
        const int MOUSEEVENTF_RIGHTUP = 0x10;        /// <summary>
        /// 鼠标的位置
        /// </summary>
        public struct PONITAPI
        {
            public int x, y;
        }        [DllImport("user32.dll")]
        public static extern int GetCursorPos(ref PONITAPI p);        [DllImport("user32.dll")]
        public static extern int SetCursorPos(int x, int y);        [DllImport("user32.dll")]
        public static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);        [STAThread]
        static void Main()
        {
            PONITAPI p = new PONITAPI();
            //GetCursorPos(ref p);
            //Console.WriteLine("鼠标现在的位置X:{0}, Y:{1}", p.x, p.y);
            //Console.WriteLine("Sleep 1 sec...");
            //Thread.Sleep(1000);
            p.x = 40;
            p.y = 30;
            //p.x = (new Random()).Next(Screen.PrimaryScreen.Bounds.Width);
            //p.y = (new Random()).Next(Screen.PrimaryScreen.Bounds.Height);
            Console.WriteLine("把鼠标移动到X:{0}, Y:{1}", p.x, p.y);
            //System.Windows.Forms.Cursor.Position = new System.Drawing.Point(5, 5);
            //Console.ReadKey();
            SetCursorPos(p.x, p.y);
            GetCursorPos(ref p);
            Console.WriteLine("鼠标现在的位置X:{0}, Y:{1}", p.x, p.y);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            Console.WriteLine("在X:{0}, Y:{1} 按下鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTDOWN, p.x, p.y, 0, 0);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            mouse_event(MOUSEEVENTF_LEFTDOWN, p.x, p.y, 0, 0);
            Console.WriteLine("在X:{0}, Y:{1} 释放鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTUP, p.x, p.y, 0, 0);
            Thread.Sleep(1000);            p.x = 50;
            p.y = 55;
            SetCursorPos(p.x, p.y);
            GetCursorPos(ref p);
            Console.WriteLine("在X:{0}, Y:{1} 按下鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTDOWN, p.x, p.y, 0, 0);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            Console.WriteLine("在X:{0}, Y:{1} 释放鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTUP, p.x, p.y, 0, 0);
            //Console.WriteLine("程序结束，按任意键退出....");
            //Console.ReadKey();
        }    }
}

实现Ctrl+S保存：
在keydown事件中，ctrl捕捉后再预定捕捉S键事件：
例子（ArcGIS中的，winform程序差不多）
         /// <summary>
        /// 保存当前编辑Ctrl+S
        /// </summary>
        /// <param name="e"></param>
        public void SaveEdit(IMapControlEvents2_OnKeyDownEvent e)
        {
            if (e.keyCode == (int)Keys.ControlKey)
            {
                m_App.MainMapControl.OnKeyDown +=
                    new IMapControlEvents2_Ax_OnKeyDownEventHandler(ForCtrlAndS_OnKeyDown);
            }
        }        private void ForCtrlAndS_OnKeyDown(object sender, IMapControlEvents2_OnKeyDownEvent e)
        {
            if (e.keyCode == (int)Keys.S)
                m_App.SaveEdit();
        }
