An Enum Type’s ToString Method Displays the Member’s Name

Normally, when you call the ToString method on a variable that stores an integer value, the value of the integer is displayed.

int x = 42;
Console.WriteLine(x.ToString());   // Displays: 42
Console.WriteLine(x);     // Same thing--ToString implicitly called
If you call ToString on an enum type variable, however, the textual name of the enumerated member is displayed.
