Accepted answer
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

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
