Remove everything which is duplicate in a List<List<double[]

Question

Hi, I hope you can help me out on this one.

 

I have a List < List < double[] > > and I want to remove everything which is duplicate in such list. That is:

1) Within the List < double[] > there are some of the double[] which are duplicate.I want to keep only the non-duplicate doubles[] within the List < double[] >. 

2) Within List < List < double[] > > there are some of the List < double[] > which are duplicate. I want to keep only the non-repeated lists. 

 

I have tried the following but it doesn't work.

public static List<List<double[]>> CleanListOfListsOfDoubleArray(List<List<double[]>> input)

{

      var output = new List<List<double[]>>();

      for (int i = 0; i < input.Count; i++)

      {

            var temp= input[i].Distinct().ToList();

            output.Add(temp);

      }

      return output.Distinct().ToList();

}

 

 

Any suggestions?

 

Many thanks!!!
