Adds a remark attribute for the enumeration (enum) type and obtains the enumerated property value.

Enumeration type (also called enumeration) is a very interesting value type. It not only improves the readability of the program, but also reduces program changes caused by business changes.

In addition, the enumeration type is strongly typed. The accept method must have the same matching parameter. Otherwise, an error will occur.

Well, let's just put it bluntly. As for the features of the enumeration type (emun), almost all programmers will understand it. I'm not doing anything here.

The following is an example, which is written on the official website by week:

 

Code

     class Program
    {
        static void Main(string[] args)
        {

            Console.Write(GetDays(Days.Saturday));
            Console.Read();
        }

        static string GetDays(Days _days)
        {
            string d = string.Empty;
            switch (_days)
            {
                case Days.Monday: d = "Today is Monday."; break;
                case Days.Tuesday: d = "Today is Tuesday."; break;
                case Days.Wednesday: d = "Today is Wednesday."; break;
                case Days.Thursday: d = "Today is Thursday."; break;
                case Days.Friday: d = "Today is Friday."; break; ;
                case Days.Saturday: d = "Today is Saturday."; break;
                case Days.Sunday: d = "Today is Sunday."; break;
            }
            return d;
        }

    }

    public enum Days
    {
        /// <summary>
        /// this is sunday
        /// </summary>
        Sunday = 7,
        /// <summary>
        /// this is monday
        /// </summary>
        Monday = 1,
        /// <summary>
        /// this is tuesday
        /// </summary>
        Tuesday = 2,
        /// <summary>
