Return first element in SortedList in C#

Question

Hello,

I have a SorterList in C# and I want to return the first element of the list. I tried using the "First" function but it didnt really work.

Can someone please tell me how to do it?

Thanks in advance,

Greg

Answer 1

Use GetByIndex

if (list.Count > 0)
  return list.GetByIndex(0);

Answer 2

SortedList listX = new SortedList();

listX.Add("B", "B");
listX.Add("A", "A");

MessageBox.Show(listX.Values(0));

Gordon Bell replied, but in the case you need to get the first key as well.

For the non generic collection:

        SortedList tmp2 = new SortedList();
        tmp2.Add("temp", true);
        tmp2.Add("a", false);
        Object mykey = tmp2.GetKey(0);
        Object myvalue = tmp2.GetByIndex(0);

For the generic collection:

        SortedList<String, Boolean> tmp = new SortedList<String, Boolean>();
        tmp.Add("temp", true);
        tmp.Add("a", false);

        String firstKey = tmp.Keys[0];
        bool firstval = tmp[firstKey];
