Sao chép HybridDictionary sang Array Instance trong C#

Để sao chép các entry của HybridDictionary sang một instance Array, ta dùng phương thức CopyTo. Dưới đây là các ví dụ.

Ví dụ 1

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("\nCopied 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);
    }
}

        Console.WriteLine("\nCopied 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);
    }
}
