Question

So I’ve been poking around with C# a bit lately, and all the Generic Collections have me a little confused. Say I wanted to represent a data structure where the head of a tree was a key value pair, and then there is one optional list of key value pairs below that (but no more levels than these). Would this be suitable?

public class TokenTree {     public TokenTree()     {         /* I must admit to not fully understanding this,          * I got it from msdn. As far as I can tell, IDictionary is an          * interface, and Dictionary is the default implementation of          * that interface, right?          */         SubPairs = new Dictionary<string, string>();     }      public string Key;     public string Value;     public IDictionary<string, string> SubPairs; } 

It’s only really a simple shunt for passing around data.

Answer 1

There is an actual Data Type called KeyValuePair, use like this

KeyValuePair<string, string> myKeyValuePair = new KeyValuePair<string,string>('defaultkey', 'defaultvalue');
