.net c# winform模拟键盘输入内容

.net c# winform 如果想模拟键盘输入内容,非常简单,3个步骤搞定

1. 获取当前所在的进程.

        /// <summary>
        /// 获取当前正在运行的应用程序
        /// </summary>
        /// <param name="name">应用程序名称</param>
        /// <returns></returns>
        public Process ProcessGet(string name)
        {
            var processes = Process.GetProcessesByName(name);
            if (processes == null || processes.Length <= 0) return null;
            foreach (var thisproc in processes)
            {
                var strBuilder = new StringBuilder(256);
                Win32.GetWindowText(thisproc.MainWindowHandle, strBuilder, 256);
                var txt = strBuilder.ToString();
                if (string.IsNullOrEmpty(txt)) return thisproc;
                if ("BOSSLOGIN:" + name == txt) return thisproc;
                if (txt.IndexOf("BOSSLOGIN:") == 0) continue;
                return thisproc;
            }
            return null;
        }

2.将程序置于最前方,如果该程序光标已经在指定的地方,在直接忽略该步骤,如果不在,这需要模拟点击,将光标置于要输入内容的位置.

        public Point ProcessShow(Process pross)
        {
            Win32.RECT rect;
            Win32.GetWindowRect(pross.MainWindowHandle, out rect);
            Point _point = new Point(rect.Left, rect.Top);
            Win32.ShowWindow(pross.MainWindowHandle, Win32.WindowAction.Show);
            Win32.SetForegroundWindow(pross.MainWindowHandle);
            return _point;
        }

        public void ProcessClick(int x, int y, Point point)
        {
            x += point.X;
            y += point.Y;
            Win32.SetCursorPos(x, y);
            Win32.mouse_event((int)(Win32.MouseEventFlags.LeftDown | Win32.MouseEventFlags.Absolute), x, y, 0, 0);
            Thread.Sleep(50);
            Win32.mouse_event((int)(Win32.MouseEventFlags.LeftUp | Win32.MouseEventFlags.Absolute), x, y, 0, 0);
            Thread.Sleep(150);
        }

调用:

        private void zbtnclick_Click(object sender, EventArgs e)
        {
            SiteProcess item = new SiteProcess();
            string name = zproname.Text;
            var process = item.ProcessGet(name);
            if (process == null) { MessageBox.Show("程序未启动"); return; }
            Point point = item.ProcessShow(process);
            item.ProcessClick(item.FormatInt(zx.Text, 0), item.FormatInt(zy.Text, 0), point);

        }

3.这个时候,只要模拟输入内容即可.

        public void InputMsg(IntPtr handle, string strtext)
        {
            foreach(var s in strtext)
            {
                SendKeys.SendWait(s.ToString());
                Thread.Sleep(50);
            }
            Thread.Sleep(100);
        }

调用:

        private void zbtninput_Click(object sender, EventArgs e)
        {
            SiteProcess item = new SiteProcess();
            string name = zproname.Text;
            var process = item.ProcessGet(name);
            if (process == null) { MessageBox.Show("程序未启动"); return; }
            Point point = item.ProcessShow(process);
            item.ProcessClick(item.FormatInt(zx.Text, 0), item.FormatInt(zy.Text, 0), point);
            Thread.Sleep(2000);
            item.InputMsg(process.MainWindowHandle, ztxtcon.Text);
        }
