Removing the specified key entry from HybridDictionary in C#
To remove the specified key entry from HybridDcitionary, the code is as follows −
Example
Live Demo
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
HybridDictionary dict1 = new HybridDictionary();
dict1.Add("A", "Books");
dict1.Add("B", "Electronics");
dict1.Add("C", "Smart Wearables");
dict1.Add("D", "Pet Supplies");
dict1.Add("E", "Clothing");
dict1.Add("F", "Footwear");
Console.WriteLine("HybridDictionary1 elements...");
foreach(DictionaryEntry d in dict1) {
Console.WriteLine(d.Key + " " + d.Value);
}
HybridDictionary dict2 = new HybridDictionary();
dict2.Add("1", "One");
dict2.Add("2", "Two");
dict2.Add("3", "Three");
dict2.Add("4", "Four");
dict2.Add("5", "Five");
dict2.Add("6", "Six");
Console.WriteLine("\nHybridDictionary2 key-value pairs...");
IDictionaryEnumerator demoEnum = dict2.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
dict2.Remove("3");
Console.WriteLine("\nHybridDictionary2 key-value pairs...UPDATED");
demoEnum = dict2.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}Output
This will produce the following output −
HybridDictionary1 elements...
A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
HybridDictionary2 key-value pairs...
Key = 1, Value = One
Key = 2, Value = Two
Key = 3, Value = Three
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six
HybridDictionary2 key-value pairs...UPDATED
Key = 1, Value = One
Key = 2, Value = Two
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six
Example
Let us see another example −
Live Demo
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
HybridDictionary dict = new HybridDictionary();
dict.Add("1", "Marketing");
dict.Add("2", "Purchase");
dict.Add("3", "Sales");
dict.Add("4", "IT");
dict.Add("5", "Finance");
dict.Add("6", "Operations");
Console.WriteLine("HybridDictionary key-value pairs...");
IDictionaryEnumerator demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
dict.Remove("3");
Console.WriteLine("\nHybridDictionary key-value pairs...UPDATED");
demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
dict.Remove("4");
Console.WriteLine("\nHybridDictionary key-value pairs...UPDATED");
demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext())
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}Output
This will produce the following output −
HybridDictionary key-value pairs...
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 3, Value = Sales
Key = 4, Value = IT
Key = 5, Value = Finance
Key = 6, Value = Operations
HybridDictionary key-value pairs...UPDATED
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 4, Value = IT
Key = 5, Value = Finance
Key = 6, Value = Operations
HybridDictionary key-value pairs...UPDATED
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 5, Value = Finance
Key = 6, Value = Operations
