If you want to convert them by value, you can use this:
(SystemPersonTitles)PersonTitle.Mr; If you want to convert them by name, you can use this:
public bool TryConvertToSystemPersonTitles( PersonTitle personTitle, out SystemPersonTitles result) { string name = PersonTitle.Mr.ToString(); SystemPersonTitles converted; return Enum.TryParse(namepersonTitle.ToString(), out result); }
