Remove duplicates from array

Anonymous User222416-Feb-2013

Hi Everyone!

I have been working with a string[] array in C# that gets returned from a function call. I was wondering what the best way to remove duplicates from this

array would be? I could possibly cast to a Generic collection, but I was wondering if there was a better way to do it, possibly by using a temp array?

Thanks in advance!

Hi Ankit!

You could try this way!

int[] nAs = { 1, 2, 3, 3, 4}; 
int[] nQ = nAs.Distinct().ToArray();

Hi Ankit,

You can remove Duplicates by using a HashSet.

string[] names = {"Windows", "Oracle", "Windows", "Csharp", "Oracle", "Windows", "Telnet", "Oracle", "Csharp" };
            var AlteredSet = new HashSet<string>(names);
            foreach (string str in AlteredSet)
            {
                MessageBox.Show(str);
            }

Regards,
Shankar
