枚举类型和int以及string的相互转换

 

　　假如我们现在有一个枚举类型

　　

/// <summary>
    /// 用户类型
    /// </summary>
    public enum UserTypeEnum
    {
        /// <summary>
        /// 匿名用户
        /// </summary>
        Anonymous = 1,
        /// <summary>
        /// 学生
        /// </summary>
        Student,
        /// <summary>
        /// 教师
        /// </summary>
        Teacher,
        /// <summary>
        ///系统平台 
        /// </summary>
        SystemPlatform

    }

 

　　

　　类型转换工具类

　　

/// <summary>
    /// 用户类型转换，枚举类型和int、string类型的转换
    /// </summary>
    public class UserTypeEnumUtility
    {

        public static UserTypeEnum String2UserType(string text,bool ignoreCase)
        {
            return (UserTypeEnum)Enum.Parse(typeof(UserTypeEnum), text,ignoreCase );
        }
        public static  int UserType2Int(UserTypeEnum userType)
        {
            return (int)userType ;
        }
        public static UserTypeEnum Int2UserType(int n)
        {
            if (Enum.IsDefined(typeof(UserTypeEnum), n))
                return (UserTypeEnum)n;
            else
                throw new Exception(string.Format("{0} is not definded.", n));
        }
        public static string UserType2String(UserTypeEnum userType)
        {
            return userType.ToString();
        }
    }
