每次我调用函数mouse_event我都会收到错误
对PInvoke函数的调用使堆栈失衡。这很可能是因为托管PInvoke签名与非托管目标签名不匹配。检查PInvoke签名的调用约定和参数是否与目标非托管签名匹配。
const int MOUSEEVENTF_LEFTDOWN = 0x02;
const int MOUSEEVENTF_LEFTUP = 0x04;
const int MOUSEEVENTF_RIGHTDOWN = 0x08;
const int MOUSEEVENTF_RIGHTUP = 0x10;
[System.Runtime.InteropServices.DllImport("user32.dll", CallingConvention = System.Runtime.InteropServices.CallingConvention.Cdecl)]
public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);
switch (mouseAction)
{
case ENUMMouseAction.LEFTDOWN:
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
break;
case ENUMMouseAction.LEFTUP:
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
break;
case ENUMMouseAction.RIGHTDOWN:
mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0);
break;
case ENUMMouseAction.RIGHTUP:
mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0);
break;
}
我已经尝试了所有可用的CallingConventions,似乎没有任何工作,任何帮助将不胜感激,
提前谢谢。

两个错误:
Stdcall

,最后一个参数是UIntPtr
