How can I convert an Enumeration member to string and vice-versa

To convert an enum to string, do this:

string enumEntryAsString = Enum.GetName(typeof(TabSizeMode), TabSizeMode.FillToRight);

To convert a string to an enum type:

// Enclose this code within try/catch.
TabSizeMode sizeMode = Enum.Parse(typeof(TabSizeMode), '1');
(or)
TabSizeMode sizeMode = Enum.Parse(typeof(TabSizeMode), 'FillToRight');
