C# में Dictionary.Remove() मेथड का उपयोग Dictionary<TKey, TValue> से निर्दिष्ट कुंजी के साथ मान को हटाने के लिए किया जाता है।
सिंटैक्स
निम्नलिखित सिंटैक्स है:
public bool Remove (TKey key);
यहाँ, key वह कुंजी है जिसे हटाना है।
उदाहरण
आइए अब Dictionary.Remove() मेथड को लागू करने का एक उदाहरण देखें:
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);
}
}
}
आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा:
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
उदाहरण
आइए अब Dictionary.Remove() मेथड को लागू करने का एक और उदाहरण देखें:
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);
}
}
}
आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा:
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
