C#Enum枚举显示中文描述（DescriptionAttrib

主要依靠DescriptionAttribute特性实现

using System;
using System.ComponentModel;
using UnityEngine;

public class EnumTest : MonoBehaviour
{
    public enum EResType
    {
        [Description("编译器")]
        Editor = 1,
        [Description("本地")]
        Res = 2,
        [Description("运行时")]
        AB = 3,
    }

    void Awake()
    {
        foreach (var var in Enum.GetValues(typeof(EResType)))
        {
            string desc = GetDescription((EResType)var);
            Debug.Log(desc);
        }
    }
    string GetDescription(Enum val)
    {
        var field = val.GetType().GetField(val.ToString());
        var customAttribute = Attribute.GetCustomAttribute(field, typeof(DescriptionAttribute));
        return customAttribute == null ? val.ToString() : ((DescriptionAttribute)customAttribute).Description;
    }

}
