c#中Enum的轉換

一、Enum的定義　
 public enum UserRolesType
    {
       
        UnKnown=0,
        BaseSimple=70,
        BaseBasic=71,
        BaseExtend=72,
        BaseBasic2=88,
        BaseSimple2=89,
        BaseExtend2=90
}
方法一：
根據ID獲取枚舉對象

protected UserRolesType GetEnum(int t)
    {
        bool isInEnum = false;
       UserRolesType c = UserRolesType.UnKnown;
        if (t > 0)
        {

            foreach(int i in Enum.GetValues(typeof(UserRolesType)))
            {
                if (i == t)
                {
                    //this.Debug(t.ToString(), "");
                    c =(UserRolesType)Enum.Parse(typeof(UserRolesType),i.ToString());
                    isInEnum = true;
                    return c;
                    //(Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
                }
         

;     
            }
            if (isInEnum == false)
            {
                return UserRolesType.UnKnown;
            }

        }
        return c;

    }
方法二：根據ID獲取枚舉名稱
 protected string GetEnumName(int s)
    {
        string str=Enum.GetName(typeof(UserRolesType), s);
        if (str == null)
        {
            str = UserRolesType.UnKnown.ToString();
        }
       return str;
    }
