Question

I have this c# code that builds a string of comma seperated matches for a service:

for (m = r.Match(site); m.Success; m = m.NextMatch())
{
     found = found + "," + m.Value.Replace(",", "");
}
return found;

Output looks like: aaa,bbb,ccc,aaa,111,111,ccc

Now that code is on .NET 4.0 How can I use C# LINQ to remove duplicates?

Also, Any way to remove duplicates without changing order?

I found this sample code in another post, but not sure exactly how to apply it:

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

Thanks.

Answer 1

string[] s = found.Split(',').Distinct().ToArray()
