Solution 3

This solution is using linq:

C#

string[] input = new string[]{"one","two","tree","tree","one","four"};
input = input.ToList().Distinct().ToArray();

It will work, my 5. Even better -- keep data without duplicate in first place, use HashSet, Dictionary.

Solution 2

Try this,

CString StrArray;
StrArray.Add("aa");
StrArray.Add("bb");
StrArray.Add("cc");
bool flag =0 ;
CString NewStrToAdd = "dd"
for(int y = 0 ;y < StrArray.GetCount(); y++)
{
   if(NewStrToAdd == StrArray.ElementAt(y))
   {
      flag = 1;
      break;
   }
}
if(flag == 0)
{
   StrArray.Add(NewStrToAdd );
}
