Enum from string, int, etc

Question

Using extension method we can create methods to convert an enum to other datatype like string, int by creating extension methods ToInt(), ToString()

Answer 1

Do you really need those extension methods?

MyEnum fromInt = (MyEnum)someIntValue;
MyEnum fromString = (MyEnum)Enum.Parse(typeof(MyEnum), someStringValue, true);

int intFromEnum = (int)MyEnum.SomeValue;
string stringFromEnum = MyEnum.SomeValue.ToString();
