using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict = new HybridDictionary();
      dict.Add("1", "SUV");
      dict.Add("2", "AUV");
      dict.Add("3", "Utility Vehicle");
      dict.Add("4", "MUV");
      dict.Add("5", "Compact Car");
      dict.Add("6", "Convertible");
      Console.WriteLine("HybridDictionary Key and Value pairs...");
      foreach(DictionaryEntry entry in dict){
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      DictionaryEntry[] dictArr = new DictionaryEntry[10];
      Console.WriteLine("
Copied to Array Instance...");       dict.CopyTo(dictArr, 2);       for (int i = 0; i < dictArr.Length; i++)          Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);    } }

输出

这将产生以下输出

HybridDictionary Key and Value pairs... 1 and SUV
2 and AUV
3 and Utility Vehicle
4 and MUV
5 and Compact Car
6 and Convertible

Copied to Array Instance...
Key = , Value =
Key = , Value =
Key = 1, Value = SUV
Key = 2, Value = AUV
Key = 3, Value = Utility Vehicle
Key = 4, Value = MUV
Key = 5, Value = Compact Car
Key = 6, Value = Convertible
Key = , Value =
Key = , Value =

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict = new HybridDictionary(10);
      dict.Add("1", "SUV");
      dict.Add("2", "AUV");
      dict.Add("3", "Utility Vehicle");
      dict.Add("4", "MUV");
      Console.WriteLine("HybridDictionary Key and Value pairs...");
      foreach(DictionaryEntry entry in dict){
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      DictionaryEntry[] dictArr = new DictionaryEntry[10];
      Console.WriteLine("
Copied to Array Instance...");       dict.CopyTo(dictArr, 0);       for (int i = 0; i < dictArr.Length; i++)          Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);    } }

输出

这将产生以下输出

HybridDictionary Key and Value pairs... 1 and SUV
2 and AUV
3 and Utility Vehicle
4 and MUV

Copied to Array Instance...
Key = 1, Value = SUV
Key = 2, Value = AUV
Key = 3, Value = Utility Vehicle
Key = 4, Value = MUV
Key = , Value =
Key = , Value =
Key = , Value =
Key = , Value =
Key = , Value =
Key = , Value =
