Hi,

I hope someone can help me with the following prob..

I need to implement a hashtable (or a dictionary) whose KEYs are
strings and VLAUEs are
again hashtables.
ie key - is a string and value -is another hashtable .
I want to implement it in C# .net  but dont know the proper syntax to
start with. Is it possible with C# 2.0 generics?

Please help.

Thanks & regards ,

aryan.

Hello Aryan,

What's wrong with custom collection?!
Start from there http://www.ondotnet.com/pub/a/dotnet/2003/09/02/ilist.html
or see Power Collection for .NET http://www.wintellect.com/PowerCollections.aspx

What about Dictionary<string, Dictionary<TKey, TValue>> where TKey and
TValue are types you choose for the stored Dictionary.

I would go Dictionary, rather than Hashtable only. You could use only
hashtable for that, since the hashtable stores any type of object as value.
But with Dictionary, you stop that boxing/unboxing thing.

                new Dictionary<string, Dictionary<string, string>>();

            dict.Add("Key", new Dictionary<string, string>());
            dict["BaseKey"].Add("SubKey", "Value");

            foreach (KeyValuePair<string, Dictionary<string, string>>
entry in dict)
            {
                listBox1.Items.Add(entry.Key);
                foreach (KeyValuePair<string, string> subEntry in
dict[entry.Key])
                {
                    listBox2.Items.Add(subEntry.Key);
                    foreach (string str in dict[entry.Key].Values)
                    {
                        listBox2.Items.Add(str);
