我正在使用平台/调用，我正在尝试将浮点 LPSTR 和 int 编组到 c++ 函数，我收到以下错误：对 PInvoke 函数“Game！Game.Graphics::CreateModel”的调用使堆栈不平衡。这可能是因为托管 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。这是我的 C# 代码：

public struct Graphics
        {
        [DllImport(@"Graphics.dll", EntryPoint = "StartGL")]
        public static extern void StartGL();
        [DllImport(@"Graphics.dll", EntryPoint = "CreateModel")]
        public static extern void CreateModel([MarshalAs(UnmanagedType.LPStr)]string ModelPath, [MarshalAs(UnmanagedType.LPStr)]string TexturePath,float xposh, float yposh, float zposh, float rotAngleh, float xroth, float yroth, float zroth);
        [DllImport(@"Graphics.dll", EntryPoint = "rotateModel")]
        public static extern void rotateModel(int id,float rotAngle,float x, float y, float z);
        }
    class Program
    {
        static void Main(string[] args) 
        {
            OpenGL();
        }
        static void OpenGL()
        {
            Graphics.CreateModel("box.obj","asd.png",0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f);
            Graphics.rotateModel(0,1.5707963267948966192313216916398f, 1.0f, 0.0f, 0.0f);
            Graphics.StartGL();
            //end of program
        }

和 c++ 函数的声明：

extern "C"  __declspec(dllexport)void StartGL();
extern "C"  __declspec(dllexport)void CreateModel(LPSTR ModelPath,LPSTR TexturePath,float xposh,float yposh,float zposh,float rotAngleh,float xroth,float yroth,float zroth)
{
    m3Dobject mod = m3Dobject(ModelPath,TexturePath,xposh,yposh,zposh,rotAngleh,xroth,yroth,zroth);
    Models.push_back(mod);
}
    extern "C"  __declspec(dllexport)void moveModel(int id,float x,float y,float z)
{
    Models[id].xpos = x;
    Models[id].ypos = y;
    Models[id].zpos = z;
}
extern "C"  __declspec(dllexport)void rotateModel(int id,float rotAnglef,float x,float y,float z)
{
    Models[id].rotAngle = rotAnglef;
    Models[id].xrot = x;
    Models[id].yrot = y;
    Models[id].zrot = z;
}

提前感谢您的帮助。

默认情况下，C++ 使用__cdecl调用约定，但 C# 默认为__stdcall. 因此，您需要在 PInvoke 声明中指定这一点，即::

[DllImport(@"Graphics.dll", EntryPoint = "StartGL", CallingConvention=CallingConvention.Cdecl)]
