Enum is a type for which the memory will be allocated on the stack instead of the heap. It can be used to write presentable code in place where we will be using integers. For Ex.

Enum Declaration

private Enum OperationalResult
{
Success = 1,
Failure = 2
}

Enum Usage

Switch (result)
{
case: (int)OperationalResult.Success
MessageBox.Show("Yippe,Operation Success");
break;
case: (int)OperationalResult.Failure
MessageBox.Show("OOPS! It's a failure");
break;
default:
MessageBox.Show("OOPS! Canno determine");
break;
}

Here in the above code, if the following statement
(int)OperationalResult.Success is replaced with 1, it does not make sense and a new developer looking at the wouldn't understand what 1 represents.
