在C++中定义需要在C#和C++中实现的接口

class Interface {
public:
    virtual ~Interface() {}
    virtual void method1() = 0;
    virtual int method2(int arg1, int arg2) = 0;
};

using System;
using System.Runtime.InteropServices;

public unsafe class CSharpClass : Interface {
    public void method1() {
        // 实现方法1
    }

    public int method2(int arg1, int arg2) {
        // 实现方法2
    }
}

[StructLayout(LayoutKind.Sequential)]
public struct Interface {
    public IntPtr method1;
    public IntPtr method2;
}

extern "C" {
    class CppClass : public Interface {
    public:
        void method1() override {
            // 实现方法1
        }

        int method2(int arg1, int arg2) override {
            // 实现方法2
        }
    };
}
