C#——在记录良好的函数上检测到 PInvokeStackImbalance？

Question

这是我的 ClickMouse() 函数代码:

    [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
    public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);


    private const long MOUSEEVENTF_LEFTDOWN = 0x02;
    private const long MOUSEEVENTF_LEFTUP = 0x04;
    private const long MOUSEEVENTF_RIGHTDOWN = 0x08;
    private const long MOUSEEVENTF_RIGHTUP = 0x10;
    private void ClickMouse()
    {
        long X = Cursor.Position.X;
        long Y = Cursor.Position.Y;
        mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);

    }

由于某些原因，当我的程序运行到这段代码时，它会抛出这样的错误信息:

PInvokeStackImbalance was detected Message: A call to PInvoke function 'WindowsFormsApplication1!WindowsFormsApplication1.Form1::mouse_event' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

请帮忙？

看起来你的 DllImport 声明是错误的。特别是使用 Int64(长整数)，而不是 UInt32。

下面是 PInvoke 引用中的一些细节:
http://www.pinvoke.net/default.aspx/user32.mouse_event

[DllImport("user32.dll")]
static extern void mouse_event(uint dwFlags, uint dx, uint dy, 
                               uint dwData,UIntPtr dwExtraInfo);
