Insert a new entry in OrderedDictionary with specified key and value in C#
To insert a new entry in OrderedDictionary with specified key and value, the code is as follows −
Example
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict = new OrderedDictionary();
dict.Add("1", "One");
dict.Add("2", "Two");
dict.Add("3", "Three");
dict.Add("4", "Four");
dict.Add("5", "Five");
dict.Add("6", "Six");
dict.Add("7", "Seven");
dict.Add("8", "Eight");
Console.WriteLine("Elements...");
IDictionaryEnumerator demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
dict.Insert(7, "15", "Fifteen");
Console.WriteLine("Elements...UPDATED");
demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}
}Output
This will produce the following output −
Elements... 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 Elements...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 = 15, Value = Fifteen Key = 8, Value = Eight
Example
Let us now see another example −
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict = new OrderedDictionary();
dict.Add("A", "Laptop");
dict.Add("B", "Desktop");
Console.WriteLine("Elements...");
IDictionaryEnumerator demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
dict.Add("C", "Ultrabook");
dict.Add("D", "Alienware");
Console.WriteLine("
Elements...UPDATED");
demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
dict.Insert(2, "K", "Speakers");
Console.WriteLine("
Elements...UPDATED");
demoEnum = dict.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
}
}
}Output
This will produce the following output −
Elements... Key = A, Value = Laptop Key = B, Value = Desktop Elements...UPDATED Key = A, Value = Laptop Key = B, Value = Desktop Key = C, Value = Ultrabook Key = D, Value = Alienware Elements...UPDATED Key = A, Value = Laptop Key = B, Value = Desktop Key = K, Value = Speakers Key = C, Value = Ultrabook Key = D, Value = Alienware
