Find unique strings for a string array

Question

Hello everyone I have a string array but may have duplicate strings. Any built-in or smart way to remove the duplicate ones and generate a string array contains only unique ones? For example the input array is {abc bcd abc} the unique output array is {abc bcd}. thanks in advance George

You have to do it manually. You could do it like this. string[] array = new string[]{onetwothreetwofouronefive}; List list = new List (); for (int i=0; i { if (!list.Contains(array[i])) list.Add(array[i]); } string[] newArray = list.ToArray();
