Answer 1

You can't use the same key in a Dictionary/Hashtable. I think you want to use a List for every key, for example (VB.NET):

Dim dic As New Dictionary(Of String, List(Of String))
Dim myValues As New List(Of String)
myValues.Add("test")
myValues.Add("Test1")
dic.Add("1", myValues)

C#:

Dictionary> dic = new Dictionary>();
List myValues = new List();
myValues.Add("test");
myValues.Add("Test1");
dic.Add("1", myValues);
