Delete duplicates in a List of int arrays

Question

having a List of int arrays like:

List intArrList = new List();
intArrList.Add(new int[3] { 0, 0, 0 });
intArrList.Add(new int[5] {         


        

Answer 1

List CopyString1 = new List();
CopyString1.AddRange(intArrList);
List CopyString2 = new List();
CopyString2.AddRange(intArrList);
for (int i = 0; i < CopyString2.Count(); i++)
{
    for (int j = i; j < CopyString1.Count(); j++)
    {
        if (i != j && CopyString2[i].Count() == CopyString1[j].Count())
        {
            var cnt = 0;
            for (int k = 0; k < CopyString2[i].Count(); k++)
            {
                if (CopyString2[i][k] == CopyString1[j][k])
                    cnt++;
                else
                    break;
            }
            if (cnt == CopyString2[i].Count())
                intArrList.RemoveAt(i);
        }
    }
}
