It depends what you mean by default value. If you define an enum like so: enum Colors { Red, Blue, Green } then by default the value of the first constant, Red, is 0 and the other values then form a sequence - Blue is 1 and Green is 2. However, if you define it like this: enum Colors { Red = 1, Blue, Green } then numbering starts at 1 and there's no constant corresponding to 0. If you define an enum as a field of some class: public Colors colors; then the default value will also be 0 whether it actually corresponds to an enum constant or not. If you define an enum as a local variable: Colors colors; then there's no default value and you have to assign it a value before you can use it.

If you declare a different value in the first member of Enum then it assign the next value greater by one than that of the immediately preceding member enum Tempurature { Low = 2, Medium, High, }; The value of Medium is 3 Source: http://csharp.net-informations.com/statements/enum.htm Vyar

Hi default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1.

Hi Vineet, Integers in the C# programming language are always initialized to zero when they are fields of a class. When you have an enum field, it will also be initialized to zero. To make enums valid, always use the default value of zero Please refer the below link http://www.dotnetperls.com/enum Thanks
