C#-এ SortedDictionary.Item[] বৈশিষ্ট্য

C#-এ SortedDictionary.Item[] বৈশিষ্ট্যটি ব্যবহার করা হয় নির্দিষ্ট কী (key)-এর সাথে যুক্ত মান (value) পাওয়ার বা সেট করার জন্য।

সিনট্যাক্স

সিনট্যাক্স নিম্নরূপ -

public TValue this[TKey k] { get; set; }

উপরে, মান k হলো পাওয়ার বা সেট করার মানের কী।

using System.Collections.Generic; 
public class Demo { 
    public static void Main(){ 
        SortedDictionary sortedDict = new SortedDictionary();

        sortedDict.Add(3, "Three"); 
        sortedDict.Add(4, "Four"); 
        sortedDict.Add(5, "Five"); 
        sortedDict.Add(6, "Six"); 
        Console.WriteLine("SortedDictionary key-value pairs..."); 
        IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); 
        while (demoEnum.MoveNext()) 
            Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); 
        Console.WriteLine("Count of SortedDictionary key-value pairs = "+sortedDict.Count); 
        sortedDict.Add(7, "Seven"); 
        sortedDict.Add(8, "Eight"); 
        Console.WriteLine("\nSortedDictionary key-value pairs...UPDATED");

        Console.WriteLine("\nCount of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count); 
    }
