一、调用Windows API。
C#下调用Windows API方法如下: 1、引入命名空间:using System.Runtime.InteropServices;
2、引用需要使用的方法,格式:[DllImport("DLL文件")]方法的声明; [DllImport("user32.dll")]private //ShowWindow参数 private const int SW_SHOWNORMAL = 1; private const int SW_RESTORE = 9; private const int SW_SHOWNOACTIVATE = 4; //SendMessage参数 private const int WM_KEYDOWN = 0X100; private const int WM_KEYUP = 0X101; private const int WM_SYSCHAR = 0X106; private const int WM_SYSKEYUP = 0X105; private const int WM_SYSKEYDOWN = 0X104; private const int WM_CHAR = 0X102;
二、找到目标窗口 1)、根据窗口的标题得到句柄 IntPtr myIntPtr = FindWindow( ShowWindow(myIntPtr, SW_RESTORE); //将窗口还原 SetForegroundWindow(myIntPtr); //如果没有ShowWindow,此方法不能设置最小化的窗口
2)、遍历所有窗口得到句柄 1 定义委托方法
2 调用EnumWindows遍历窗口 CallBack myCallBack = new CallBack(Recall); EnumWindows(myCallBack, 0);
3 回调方法Recall public bool Recall(int hwnd, int lParam) { StringBuilder sb = new StringBuilder(256); IntPtr PW = new IntPtr(hwnd);
GetWindowTextW(PW,sb,sb.Capacity); //得到窗口名并保存在strName中 string strName = sb.ToString();
GetClassNameW(PW,sb,sb.Capacity); //得到窗口类名并保存在strClass中 string strClass = sb.ToString();
if (strName.IndexOf("窗口名关键字") >= 0 && strClass.IndexOf("类名关键字") >= 0) { return false; //返回false中止EnumWindows遍历 } else { return true; //返回true继续EnumWindows遍历 } }
3)、打开窗口得到句柄 1 定义设置活动窗口API(SetActiveWindow),设置前台窗口API(SetForegroundWindow) [DllImport("user32.dll")]static extern IntPtr SetActiveWindow(IntPtr hWnd); [DllImport("user32.dll")][return: MarshalAs(UnmanagedType.Bool)]static extern bool SetForegroundWindow(IntPtr hWnd); 2 打开窗口 Process proc = Process.Start(@"目标程序路径"); SetActiveWindow(proc.MainWindowHandle); SetForegroundWindow(proc.MainWindowHandle);
三、向指定的窗口输入数据 1 利用发送消息API(SendMessage)向窗口发送数据 InputStr(myIntPtr, _GameID); //输入游戏ID SendMessage(myIntPtr, WM_SYSKEYDOWN, 0X09, 0); //输入TAB(0x09) SendMessage(myIntPtr, WM_SYSKEYUP, 0X09, 0); InputStr(myIntPtr, _GamePass); //输入游戏密码 SendMessage(myIntPtr, WM_SYSKEYDOWN, 0X0D, 0); //输入ENTER(0x0d) SendMessage(myIntPtr, WM_SYSKEYUP, 0X0D, 0);
/// <summary> /// 发送一个字符串 /// </summary> /// <param name="myIntPtr">窗口句柄</param> /// <param name="Input">字符串</param> public void InputStr(IntPtr myIntPtr, string Input) { byte[] ch = (ASCIIEncoding.ASCII.GetBytes(Input)); for (int i = 0; i < ch.Length; i++) { SendMessage(PW, WM_CHAR, ch, 0); } }
2 利用鼠标和键盘模拟向窗口发送数据 SetWindowPos(PW, (IntPtr)(-1), 0, 0, 0, 0, 0x0040 | 0x0001); //设置窗口位置 SetCursorPos(476, 177); //设置鼠标位置 mouse_event(0x0002, 0, 0, 0, 0); //模拟鼠标按下操作 mouse_event(0x0004, 0, 0, 0, 0); //模拟鼠标放开操作 SendKeys.Send(_GameID); //模拟键盘输入游戏ID SendKeys.Send("{TAB}"); //模拟键盘输入TAB SendKeys.Send(_GamePass); //模拟键盘输入游戏密码 SendKeys.Send("{ENTER}"); //模拟键盘输入ENTER
另:上面还提到了keybd_event方法,用法和mouse_event方法类似,作用和SendKeys.Send一样。
