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，请帮助我编写代码 sn-p。

Answer 1

如果我正确理解了您的问题，那么您想要真正模拟输入。在这种情况下，SendInput 是要走的路。来自this link

PInvoke 到 SendInput – 这是 模拟输入的官方方法。它 通过所有的推动输入 预期的代码路径，并且是 与真实输入无法区分。

使用此功能的简单方法是在 CodePlex 使用 InputSimulator。添加对 InputSimulator.dll 的引用，您可以模拟击键，如

// 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 的入门。到目前为止，它只支持 LeftClick 和 RightClick，但借助以下两个链接，您可以轻松地使用 MouseMove 等扩展它。
