- 根据窗口的关系获取控件
可以通过spy++获取控件的类型名称
var ptr=FindWindows("打开");
//IntPtr hwnd = FindWindow("#32770 (对话框)", "MainWindow"); //FindWindow只查找顶层窗口
//IntPtr htextbox = FindWindowEx(ptr.Value, IntPtr.Zero, "wxWindowClassNR", null);//(当前为第一层)IntPtr.Zero则表示获得第一个子窗口。第三个参数表示你需要找的子窗口的类型，第四个参数一般为null。
//IntPtr htextbox2 = FindWindowEx(hwnd, IntPtr.Zero, "wxWindowClassNR", null);//(当前为第一层)IntPtr.Zero则表示获得第一个子窗口。第三个参数表示你需要找的子窗口的类型，第四个参数一般为null。
//IntPtr htextbox2 = FindWindowEx(hwnd, htextbox, "EDIT", null);//填上次获得的句柄，可以得到下一个的句柄。
//SendMessage(ptr.Value, WM_SETTEXT, IntPtr.Zero, "123232");//发送消息
IntPtr htextbox2 = FindWindowEx(ptr.Value, IntPtr.Zero, "ComboBoxEx32", null);//填上次获得的句柄，可以得到下一个的句柄。
IntPtr htextbox22 = FindWindowEx(htextbox2, IntPtr.Zero, "ComboBox", null);//填上次获得的句柄，可以得到下一个的句柄。
IntPtr edit = FindWindowEx(htextbox22, IntPtr.Zero, "Edit", null);//填上次获得的句柄，可以得到下一个的句柄。
//SendMessage(edit, WM_SETTEXT, IntPtr.Zero, "D:\\work\\code");//发送消息
//SendMessage(edit, WM_SETTEXT, IntPtr.Zero, "C:\\Users\\xx\\Desktop\\t\\WeChat_20241109200005.mp4");//发送消息
SendMessage(edit, WM_SETTEXT, IntPtr.Zero, "C:\\Users\\xx\\Desktop\\t\\test.mp4");//发送消息
IntPtr openBtn = FindWindowEx(ptr.Value, IntPtr.Zero, "Button", null);//填上次获得的句柄，可以得到下一个的句柄。
//SendMessage(openBtn, WM_KEYDOWN, IntPtr.Zero, "D:\\work\\code");//发送消息
SendMessage(openBtn, WM_LBUTTONDOWN, IntPtr.Zero, null);//鼠标按下按钮
SendMessage(openBtn, WM_LBUTTONUP, IntPtr.Zero, null);//释放鼠标

c#获取句柄，并对第三方软件的输入框和按钮进行控制
