如何为C#包装具有多种类型的C++结构？

// C++结构体
struct MyStruct {
    int intValue;
    float floatValue;
    char stringValue[100];
};

// C++函数
extern "C" __declspec(dllexport) void ProcessStruct(MyStruct* myStruct) {
    // 处理结构体
    // ...
}

using System;
using System.Runtime.InteropServices;

// C#结构体
[StructLayout(LayoutKind.Sequential)]
struct MyStruct {
    public int intValue;
    public float floatValue;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
    public string stringValue;
}

class Program {
    // 导入C++函数
    [DllImport("MyCppLibrary.dll")]
    public static extern void ProcessStruct(ref MyStruct myStruct);

    static void Main() {
        MyStruct myStruct = new MyStruct();
        myStruct.intValue = 10;
        myStruct.floatValue = 3.14f;
        myStruct.stringValue = "Hello";

        // 调用C++函数
        ProcessStruct(ref myStruct);

        // 输出处理后的结构体成员值
        Console.WriteLine(myStruct.intValue);
        Console.WriteLine(myStruct.floatValue);
        Console.WriteLine(myStruct.stringValue);
    }
}
