C#-এ SortedDictionary.Remove() পদ্ধতি

C#-এ SortedDictionary.Remove() পদ্ধতিটি ব্যবহার করা হয় SortedDictionary<TKey, TValue>-এ থেকে নির্দিষ্ট কী (key) সহ উপাদানটি সরাতে।

সিনট্যাক্স

সিনট্যাক্স নিম্নরূপ -

public bool Remove (TKey key);

উপরে, প্যারামিটার key হলো সরাতে হবে উপাদানের কী।

উদাহরণ

এখন একটি উদাহরণ দেখি -

using System; 
using System.Collections; 
using System.Collections.Generic; 
public class Demo { 
    public static void Main(){ 
        SortedDictionary sortedDict = new SortedDictionary(); 
        sortedDict.Add(100, "Mobile"); 
        sortedDict.Add(200, "Laptop"); 
        sortedDict.Add(300, "Desktop"); 
        sortedDict.Add(400, "Speakers"); 
        sortedDict.Add(500, "Headphone"); 
        sortedDict.Add(600, "Earphone"); 
        Console.WriteLine("SortedDictionary key-value pairs..."); 
        IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); 
        while (demoEnum.MoveNext()) 
            Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); 
        Console.WriteLine("\nKey 400 removed from SortedDictionary? = "+sortedDict.Remove(400)); 
        Console.WriteLine("\nSortedDictionary key-value pairs...UPDATED"); 
        demoEnum = sortedDict.GetEnumerator(); 
        while (demoEnum.MoveNext()) 
            Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); 
        SortedDictionary.KeyCollection keyColl = sortedDict.Keys; 
        Console.WriteLine("\nKeys...list"); 
        foreach( int i in keyColl ){ 
            Console.WriteLine(i); 
        } 
    } 
}
