Question

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。如果可能，请帮我编写代码片段。

如果我理解你的问题，那么你想要真正模拟输入。在这种情况下，SendInput是要走的路。来自this link

PInvoke to SendInput - 这是模拟输入的官方方式。它推动输入通过所有预期的代码路径，是与实际输入无法区分。

使用此功能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

这样的击键

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

但是， InputSimulator 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。

{
    [DllImport("user32.dll", SetLastError = true)]
    static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);

    [StructLayout(LayoutKind.Sequential)]
    struct INPUT

    }
    public static void ClickRightMouseButton()

        mouseDownInput.type = SendInputEventType.InputMouse;

        INPUT mouseUpInput = new INPUT();
