如何在 winform 和 wpf 中以编程方式进行鼠标移动、单击、右键单击和按键等操作。如果可能，请帮助我提供代码片段。

最佳答案

如果我正确理解您的问题，那么您想要真正模拟输入。在这种情况下，SendInput 是可行的方法。来自 this link

PInvoke to SendInput – this is the official way to simulate input. It pushes the input through all of the expected code paths, and is indistinguishable from real input.

一个简单的使用方法是 InputSimulator在 CodePlex。添加对 InputSimulator.dll 的引用，您可以像这样模拟击键

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

然而，InputSimulator 尚不支持鼠标，但这里有一个 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。
