CsharpServer Side ProgrammingProgramming

To get an ICollection containing the keys in HybridDictionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict = new HybridDictionary();
      dict.Add("One", "Katie");
      dict.Add("Two", "Andy");
      dict.Add("Three", "Gary");
      dict.Add("Four", "Mark");
      dict.Add("Five", "Marie");
      dict.Add("Six", "Sam");
      dict.Add("Seven", "Harry");
      dict.Add("Eight", "Kevin");
      dict.Add("Nine", "Ryan");
      String[] strArr = new String[dict.Count];
      dict.Keys.CopyTo(strArr, 0);
      for (int i = 0; i < dict.Count; i++)
      Console.WriteLine(strArr[i]);
   }
}

      dict.Add("3", "C");
      dict.Add("4", "D");
      dict.Add("5", "E");
      dict.Add("6", "F");
      String[] strArr = new String[dict.Count];
      dict.Keys.CopyTo(strArr, 0);
      for (int i = 0; i < dict.Count; i++)
         Console.WriteLine(strArr[i]);
