Enumeration in C#.NET,VB.NET

Enumeration is a great user defined data type in C#.Net and VB.NET. It is very useful in code readability. It greatly increases the readability of code.

here is the example of the enumeration that contains the weekdays.

In C#.NET...

public enum weekdays
{
Sunday=1,
Monday=2,
Tuesday=3,
Wednesday=4,
Thursday=5,
Friday=6,
Saturday=7
}
In VB.NET...

public enum weekdays
Sunday=1,
Monday=2,
Tuesday=3,
Wednesday=4,
Thursday=5,
Friday=6,
Saturday=7,
end enum
here is the code that we can use in VB.NET

Imports System.ComponentModel
Imports System.Diagnostics
Dim enumWeekday As weekdays
Dim i As Integer
i=2
enumWeekDay=Ctype(i,weekdays)
debug.writeline(enumWeekdays.ToString())

Same way we can write in C#.NET

using System.ComponentModel;
using System.Diagnostics;

Weekdays enumWeekDays;
int i;
i=2;
enumWeekday=(Weekdays) i;
debug.writeline(enumWeekdays.ToString());



So you can see the it greatly increase readability also saves time to write code with switch case and if else
