Example

using System;
using System.Collections;

namespace Samples
{
  public class IDictionarySample
  {
    public static void Main()
    {
      IDictionary id = new Hashtable();
      id.Add(1, "damien");
      id.Add(2, "mark");
      id.Add(3, "brad");
      DisplayDictionary(id);
      SortedList sl = new SortedList();
      sl.Add(1, "maire");
      sl.Add(2, "sacha");
      sl.Add(3, "tamara");
      DisplayDictionary(sl);
    }
    public static void DisplayDictionary(IDictionary id)
    {
      Console.WriteLine("Is fixed size: {0}", id.IsFixedSize);
      Console.WriteLine("Is read only: {0}", id.IsReadOnly);
      Console.WriteLine("Count: {0}", id.Count );
      Console.WriteLine("Number of keys: {0}", id.Keys.Count);
      foreach(DictionaryEntry de in id)
        Console.WriteLine("Key: {0} Value: {1}",
                          de.Key,
                          de.Value);
    }
  }
}

The output is

 Is fixed ...
