C#捕获Windows窗体控件

  最近由于客户的需求，需要一个登陆的解决方案，但是我们需要捕获界面的控件，并赋值，然后自动登录，在网上找了一下，AutoIt这个工具不错，可以捕获的到窗体及控件，但是没有源码呀，自己动手写一个简单版的吧。

好了，下面咱们来说道说道·······

  思路分析： 我们首先要捕获鼠标的移动，当鼠标按下时，触发一个事件，然后移动鼠标到控件，释放鼠标，捕获控件。如何捕获鼠标事件呢？我们用钩子（Hook）

  

 private int MouseHookProc(int nCode, IntPtr wParam, IntPtr lParam)
        {
            MouseControl.MouseHookStruct MyMouseHookStruct = (MouseControl.MouseHookStruct)Marshal.PtrToStructure(lParam, typeof(MouseControl.MouseHookStruct));
            if (nCode < 0)
            {
                return MouseControl.CallNextHookEx(hHook, nCode, wParam, lParam);
            }
            else
            {
                if (MouseDownEvent != null)
                {
                    MouseButtons button = MouseButtons.None;
                    int clickCount = 0;
                    switch ((Int32)wParam)
                    {
                        
                        case WM_RBUTTONDOWN:
                             button = MouseButtons.Right;
                             clickCount = 1;
                             break;
                        
                    }
                    var e = new MouseEventArgs(button, clickCount, point.X, point.Y, 0);
                    MouseDownEvent(this,e); // MouseClickEvent(this, e);
                   
                 }
                if (MouseUpEvent != null)
                {
                    MouseButtons button = MouseButtons.None;
                    int clickCount = 0;
                    switch ((Int32)wParam)
                    {
                        case WM_RBUTTONUP:
                            button = MouseButtons.Right;
                            clickCount = 1;
                            break;
                    }
                    var e = new MouseEventArgs(button, clickCount, point.X, point.Y, 0);
                    MouseUpEvent(this, e);
                }
                if (MouseMoveEvent != null)
                {
                    MouseButtons button = MouseButtons.None;
                    int clickCount = 0;
                    switch ((Int32)wParam)
                    {
                        case WM_RBUTTONUP:
                            button = MouseButtons.None;
                            clickCount = 1;
                            break;
                    }
                    var e = new MouseEventArgs(MouseButtons.None, 0, point.X, point.Y, 0);
                    MouseMoveEvent(this, e);

                }
                this.Point = new Point(MyMouseHookStruct.pt.x, MyMouseHookStruct.pt.y);
                return MouseControl.CallNextHookEx(hHook, nCode, wParam, lParam);
            }
        }

　 在前台我们会调用钩子委托，来实现我们想要的结果

   

  private void mh_MouseUpEvent(object sender, MouseEventArgs e) {
           
            if (e.Button == MouseButtons.Right)
            {
                Dictionary<string, string> dic = this.m_windowDetective.DicResult();
                CursorControl.BackCursor();
                if (this.ptMouse == this.m_windowDetective.MousePosition)
                {
                    this.waitCount++;
                    if (this.waitCount < 10)
                    {
                        this.Text += ".";
                        return;
                    }
                    this.waitCount = 0;
                    this.Text = "窗口适配";
                }
                this.ptMouse = this.m_windowDetective.MousePosition;
                //this.txtWorkReport.Text = this.m_windowDetective.Result().ToString();
                txtTitle.Text = dic["标题"].ToString();
                txtClassName.Text = dic["类别"].ToString();
                txtInstance.Text = dic["INSTANCE"].ToString();
                pictureBox1.ImageLocation = Environment.CurrentDirectory + "\\Icon\\snows.png";
                
            }
        }
        private void mh_MouseMoveEvent(object sender, MouseEventArgs e)
        {
           if (e.Button == MouseButtons.None)
            {
                int x = e.Location.X;
                int y = e.Location.Y;
                this.m_windowDetective.ChangeBorder();
            }
        }
