C#-এ Dictionary.Remove() মেথডটি Dictionary<TKey, TValue>-এ নির্দিষ্ট কী (key) সহ মানটি সরাতে ব্যবহৃত হয়।
সিনট্যাক্স
নিচে সিনট্যাক্স দেওয়া হলো:
public bool Remove (TKey key);
উপরে, key হলো সরাতে হবে এমন কী।
উদাহরণ
Dictionary.Remove() মেথড বাস্তবায়নের প্রথম উদাহরণ:
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("One", "Kagido");
dict.Add("Two", "Ngidi");
dict.Add("Three", "Devillers");
dict.Add("Four", "Smith");
dict.Add("Five", "Warner");
Console.WriteLine("Count of elements = " + dict.Count);
Console.WriteLine("Removing some keys...");
dict.Remove("Four");
dict.Remove("Five");
Console.WriteLine("Count of elements (updated) = " + dict.Count);
Console.WriteLine("\nKey/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
Console.Write("\nAll the keys..\n");
Dictionary<string, string>.KeyCollection allKeys = dict.Keys;
foreach(string str in allKeys){
Console.WriteLine("Key = {0}", str);
}
}
}
আউটপুট
এটি নিচের আউটপুট তৈরি করবে:
Count of elements = 5 Removing some keys... Count of elements (updated) = 3 Key/value pairs... Key = One, Value = Kagido Key = Two, Value = Ngidi Key = Three, Value = Devillers All the keys.. Key = One Key = Two Key = Three
আরেকটি উদাহরণ (সর্বোচ্চ কী দেখানো)
সকল কী দেখানোর পর রিমুভ করা:
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("One", "Kagido");
dict.Add("Two", "Ngidi");
dict.Add("Three", "Devillers");
dict.Add("Four", "Smith");
dict.Add("Five", "Warner");
Console.WriteLine("Count of elements = " + dict.Count);
Console.Write("\nAll the keys..\n");
Dictionary<string, string>.KeyCollection allKeys = dict.Keys;
foreach(string str in allKeys){
Console.WriteLine("Key = {0}", str);
}
Console.WriteLine("Removing some keys...");
dict.Remove("Four");
dict.Remove("Five");
Console.WriteLine("Count of elements (updated) = " + dict.Count);
Console.Write("\nAll the keys..updated\n");
foreach(string str in allKeys){
Console.WriteLine("Key = {0}", str);
}
Console.WriteLine("\nKey/value pairs...");
foreach(KeyValuePair<string, string> res in dict){
Console.WriteLine("Key = {0}, Value = {1}", res.Key, res.Value);
}
}
}
আউটপুট
এটি নিচের আউটপুট তৈরি করবে:
Count of elements = 5 All the keys.. Key = One Key = Two Key = Three Key = Four Key = Five Removing some keys... Count of elements (updated) = 3 All the keys..updated Key = One Key = Two Key = Three Key/value pairs... Key = One, Value = Kagido Key = Two, Value = Ngidi Key = Three, Value = Devillers
