Find unique strings for a string array

George George

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[]{"one","two","three","two","four","one","five"};
List list = new List();

for (int i=0; i{
if (!list.Contains(array[i])) list.Add(array[i]);
}

string[] newArray = list.ToArray();
