I need some help with this, I have a fullname string and what I need to do is separate and use this fullname string as firstname and lastname separately.
This will work if you are sure you have a first name and a last name.
string fullName = "Adrian Rules"; var names = fullName.Split(' '); string firstName = names; string lastName = names;
Make sure you check for the length of
names.Length == 0 //will not happen, even for empty string names.Length == 1 //only first name provided (or blank) names.Length == 2 //first and last names provided names.Length > 2 //first item is the first name. last item is the last name. Everything else are middle names
Of course, this is a rather simplified view on the problem. The objective of my answer is to explain how
string.Split() works. However, you must keep in mind that some last names are composite names, like "Luis da Silva", as noted by @AlbertEin.
This is far from being a simple problem to solve. Some prepositions (in french, spanish, portuguese, etc.) are part of the last name. That's why @John Saunders asked "what language?". John also noted that prefixes (Mr., Mrs.) and suffixes (Jr., III, M.D.) might get in the way.
