C#sizeof(枚举)替代？(解决方法resharper false error)？

using System;
using System.Runtime.InteropServices;

namespace EnumSizeOfExample
{
    enum ExampleEnum
    {
        Value1,
        Value2,
        Value3
    }

    class Program
    {
        static void Main(string[] args)
        {
            int size = Marshal.SizeOf(typeof(ExampleEnum));
            Console.WriteLine($"Size of ExampleEnum: {size} bytes");
        }
    }
}
