C#操作窗口类(句柄操作)

C#写个类操作窗口（句柄操作）实现过程：过程一：找到当前鼠标位置的句柄您的使用2个WinAPI（俺喜欢自己封装下来用）：ViewCode[DllImport(

publicstaticextern,boolEntryPoint= )]GetCUrsorPos(outPointpt);[DllImport(

publicstaticextern,EntryPoint=IntPtrWindowFromPoint(Pointpt);)]//鼠标位置的坐标publicstaticPointGetCUrsorPosPoint(){PointP=newPoint();if(GetCursorPos(outp)){returnp;}returndefault(Point);}///<summary>///找到句柄///<∕summary>/// 坐标</param>///<returnsx/returns>publicstaticIntPtrGetHandle(PointP)

{returnWindowFromPoint(p);

}过程二：改变窗口的Text您的使用1个WinAPI:田日V■ C7ViewCode[DllImport( ,EntryPoint= )]privatestaticexternintSendMessage(IntPtrhWnd,intMsg,IntPtrWParam,string///<summary>///给窗口发送内容///</summary>lParam);///句柄</param>/// 要发送的内容<∕param>publicstaticvoidSetText(IntPtrhWnd,stringlParam){SendMessage(hWnd,WM_SETTEXT,IntPtr.Zero,lParam);}privateconstintWM_SETTEXT=0x000C;通过这个方法就能改变Text的值了。思考：如果俺把这个窗口的句柄记录下来，下次不用鼠标获取，直接就能改变值不蛮好的嘛。例如：我有个桌面系统老叫我输入用户名，密码。我记录用户名和密码的窗口句柄，然后改变他们的输入值，这样多省事。(只是举例，不考虑安全性)问题：你会告诉我，窗口句柄的每次重建会变的呀，咋办。回答：类名不变呀。过程三：您的准备一些工具吧，例如：句柄找类名呀，类名找句柄什么的等等，下面会用到一些WinAPIViewCode[DllImport(

句柄</param>///<returnsx/returns>publicstaticstringGetClassName(IntPtrhWnd){StringBuilderlpClassName=newStringBuilder(128);if(GetClassName(hWnd,IpClassName,IpClassName.Capacity)==0){thrownewException( );}returnlpClassName.ToString();}思考：遍历桌面上所有的窗口，然后找类名，然后改他的Text,扯淡嘛,相同的类名太多了，找毛呀。实现：不仅记录类名，而且记录类名在父窗口出现的位置，然后通过桌面一层层找下来，最后找到这个句柄。(虽然不是太准，但是一般的还是能解决了，如果你有什么好方式一起研究)。过程四：实现一个WinHWND的类，可以把他的规则，他的父窗口类名，以及在父窗口中同类名出现的顺序记录下来，然后通过这些记录的信息还原句柄。[+IEIt7'CJViewCodepublicclassWinHWND{publicIntPtrHWND{get;set;}publicstringClassName{get;set;}publicWinHWNDParent{get;set;}publicintInParentSequence{get;set;}privateWinHWND(){}publicWinHWND(IntPtrhWnd){this.HWND=hWnd;this.ClassName=GetClaSSName();this.Parent=GetParent();this.InParentSequence=GetInParentSeqUenCe();}privatestringGetClassName(){returnWinAPI.GetClassName(this.HWND);}privateWinHWNDGetParent(){if(WinAPI.GetParent(this.HWND)==null){thrownewException(
