แทรกรายการใหม่ใน OrderedDictionary ด้วยคีย์และค่าที่ระบุใน C #

ในการแทรกรายการใหม่ใน OrderedDictionary ด้วยคีย์และค่าที่ระบุ รหัสจะเป็นดังนี้ -

ตัวอย่าง

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);
      }
   }
}

ผลลัพธ์

สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -

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

ตัวอย่าง

เรามาดูตัวอย่างอื่นกัน −

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("\nElements...UPDATED");
      demoEnum = dict.GetEnumerator();
      while (demoEnum.MoveNext()) {
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      }
      dict.Insert(2, "K", "Speakers");
      Console.WriteLine("\nElements...UPDATED");
      demoEnum = dict.GetEnumerator();
      while (demoEnum.MoveNext()) {
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      }
   }
}

ผลลัพธ์

สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -

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
