如何在winform和wpf中以编程方式鼠标移动,单击,右键单击和按键等？

Question

如何在winform和wpf中以编程方式鼠标移动,单击,右键单击和按键等.如果可能的话,请帮我编写代码片段.

Answer 1

如果我正确理解你的问题,那么你想真正模拟输入.在那种情况下 SendInput是要走的路.从这个链接

PInvoke to SendInput - 这是模拟输入的官方方式.它通过所有预期的代码路径推送输入,并且与实际输入无法区分.

使用它的一种简单方法是在CodePlex 上使用InputSimulator.添加对InputSimulator.dll的引用,您可以模拟像键盘一样的击键

// Tab
InputSimulator.SimulateKeyDown(VirtualKeyCode.TAB);
// Shift+Tab
InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.SHIFT, VirtualKeyCode.TAB);   
// etc.

但是,InputSimulator还不支持鼠标,但这里是MouseSimulator的启动器.到目前为止它只执行LeftClick和RightClick,但在以下两个链接的帮助下,您可以使用MouseMove等轻松扩展它.
