如何在屏幕上的某个位置模拟鼠标单击? [英] How can I simulate a mouse click at a certain position on the screen?

问题描述

我想做的是操纵鼠标.出于我自己的目的，这将是一个简单的宏.所以它会将我的鼠标移动到屏幕上的某个位置并点击，就像我以一定的间隔点击一样.

What I want to do is to manipulate the mouse. It will be a simple macro for my own purposes. So it will move my mouse to certain position on the screen and click like I am clicking with certain interval.

推荐答案

这是一段使用非托管函数来模拟鼠标点击的代码:

Here's a code that is using unmanaged functions to simulate mouse clicks :

//This is a replacement for Cursor.Position in WinForms
[System.Runtime.InteropServices.DllImport("user32.dll")]
static extern bool SetCursorPos(int x, int y);

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

public const int MOUSEEVENTF_LEFTDOWN = 0x02;
public const int MOUSEEVENTF_LEFTUP = 0x04;

//This simulates a left mouse click
public static void LeftMouseClick(int xpos, int ypos)
{
    SetCursorPos(xpos, ypos);
    mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
    mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);
}

要保持鼠标按下特定的持续时间，您可以Sleep()正在执行此函数的线程，例如:

To keep the mouse pressed for a specific duration you can Sleep() the thread that is executing this function, for example :

mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
System.Threading.Thread.Sleep(1000);
mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);

上面的代码将保持鼠标按下 1 秒，除非用户按下释放鼠标按钮.另外，请确保不要在主 UI 线程上执行此代码，因为它会导致挂起.

The above code will keep the mouse pressed for 1 second unless the user presses the releases the mouse button. Also, make sure to not execute this code on the main UI thread as it will cause it to hang.
