c# - 定向鼠标事件 [DllImport ("user32.dll")] 单击，双击

Question

我试过了 [DllImport("user32.dll")] static extern bool SetCursorPos(int X, int Y);

并且将光标移动到所需点时效果很好。我以前从未尝试过这种 DLL 导入，但它有效:)。但是我想要更多我还能提取什么？ 主要是我想在没有任何鼠标输入的情况下双击、单击或使用滚轮选项，只是代码我该怎么做？以及如何检查 user32dll 中还包含什么？

谢谢

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, UIntPtr dwExtraInfo);
private const uint MOUSEEVENTF_LEFTDOWN = 0x02;
private const uint MOUSEEVENTF_LEFTUP = 0x04;
private const uint MOUSEEVENTF_RIGHTDOWN = 0x08;
private const uint MOUSEEVENTF_RIGHTUP = 0x10;

您应该导入并定义这些常量以使用 Win32API 与鼠标一起工作

使用下面的方法进行鼠标操作

void sendMouseRightclick(Point p)
{
    mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);
}

void sendMouseDoubleClick(Point p)
{
    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, p.X, p.Y, 0, 0);

Thread.Sleep(150);

    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, p.X, p.Y, 0, 0);
}

void sendMouseRightDoubleClick(Point p)
{
    mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);

    Thread.Sleep(150);

    mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, p.X, p.Y, 0, 0);
}

void sendMouseDown()
{
    mouse_event(MOUSEEVENTF_LEFTDOWN, 50, 50, 0, 0);
}

void sendMouseUp()
{
    mouse_event(MOUSEEVENTF_LEFTUP, 50, 50, 0, 0);
}

如果您想进行鼠标拖动，您应该首先发送 MouseDown(鼠标单击)并在更改鼠标位置时保持单击状态，而不是像这样发送 MouseUp(释放单击)。

sendMouseDown();
Cursor.Position = new Point(30,30);
sendMouseUp();
