C#枚举长度，顺便写个关于枚举的循环选择

获取枚举长度

---

Enum.GetValues(typeof(yourEnums)).Length;

枚举的循环选择

---

    YourEnums _yourEnums;
    public YourEnums _YourEnum
    {
        get
        {
            return _yourEnums;
        }

        set
        {
            int len = Enum.GetValues(typeof(YourEnums)).Length;
            _yourEnums = (YourEnums)Enum.ToObject(typeof(YourEnums), Mathf.Clamp(value.GetHashCode(), 0, len));
                
            if (value.GetHashCode() == -1)
            {
                _yourEnums = (YourEnums)Enum.ToObject(typeof(YourEnums), len - 1); 
                
            }
            else if (value.GetHashCode() == len)
            {
                _yourEnums = 0;
            }
        }
    }
