SortedDictionary.Item[] C# এ সম্পত্তি

C#-এ SortedDictionary.Item[] প্রপার্টি নির্দিষ্ট কী-এর সাথে যুক্ত মান পেতে বা সেট করতে ব্যবহৃত হয়।

সিনট্যাক্স

সিনট্যাক্স নিম্নরূপ -

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

উপরে, মান k হল সেই মানের কী যা পেতে বা সেট করতে হবে।

উদাহরণ

আসুন এখন একটি উদাহরণ দেখি -

using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>();
      sortedDict.Add(1, "One");
      sortedDict.Add(2, "Two");
      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");
      demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      Console.WriteLine("Count of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
      Console.WriteLine("Value in the SortedDictionary key-value pair key five = "+sortedDict[5]);
      sortedDict.Clear();
      Console.WriteLine("\nCount of SortedDictionary key-value pairs (UPDATED) = "+sortedDict.Count);
   }
}

আউটপুট

এটি নিম্নলিখিত আউটপুট −

Key = 1, Value = One
Key = 2, Value = Two
Key = 3, Value = Three
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six
Count of SortedDictionary key-value pairs = 6
SortedDictionary key-value pairs...UPDATED
Key = 1, Value = One
Key = 2, Value = Two
Key = 3, Value = Three
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six
Key = 7, Value = Seven
Key = 8, Value = Eight
Count of SortedDictionary key-value pairs (UPDATED) = 8
Value in the SortedDictionary key-value pair key five = Five
Count of SortedDictionary key-value pairs (UPDATED) = 0

      sortedDict.Add(4, "AUV");
      sortedDict.Add(5, "Hatchback");
      sortedDict.Add(6, "Convertible");
      Console.WriteLine("SortedDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
