การค้นหาใน SortedList Object ด้วย C#

โค้ดสำหรับค้นหาใน SortedList Object มีดังนี้:

ตัวอย่าง

using System; 
using System.Collections; 
public class Demo { 
    public static void Main() { 
        SortedList list = new SortedList(); 
        list.Add("1", "One"); 
        list.Add("2", "Two"); 
        list.Add("3", "Three"); 
        list.Add("4", "Four"); 
        list.Add("5", "Five"); 
        list.Add("6", "Six"); 
        list.Add("7", "Seven"); 
        list.Add("8", "Eight"); 
        Console.WriteLine("Key and Value of SortedList...."); 
        foreach(DictionaryEntry k in list ) 
            Console.WriteLine("Key: {0}, Value: {1}", k.Key , k.Value ); 
        Console.WriteLine("Is the SortedList having the value? " + list.ContainsValue("Three")); 
        Console.WriteLine("The SortedList object has a fixed size? = " + list.IsFixedSize); 
        Console.WriteLine("Does the SortedList object contains key 10? = " + list.ContainsKey("10")); 
    } 
}

ผลลัพธ์

จะได้ผลลัพธ์ดังนี้:

Key and Value of SortedList.... 
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 
Is the SortedList having the value? True 
The SortedList object has a fixed size? = False 
Does the SortedList object contains key 10? = False

        sortedList.Add("H", "8"); 
        sortedList.Add("I", "9"); 
        sortedList.Add("J", "10"); 
        Console.WriteLine("SortedList elements..."); 
        foreach(DictionaryEntry d in sortedList) { 
            Console.WriteLine("Key = " + d.Key + ", Value = " + d.Value); 
        } 
        Console.WriteLine("Count of SortedList key-value pairs = " + sortedList.Count); 
        Console.WriteLine("\nEnumerator to iterate through the SortedList..."); 
        IDictionaryEnumerator demoEnum = sortedList.GetEnumerator(); 
        while (demoEnum.MoveNext()) 
            Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); 
        Console.WriteLine("Does the SortedList object contains key M? = " + sortedList.ContainsKey("M")); 
        Console.WriteLine("Does the SortedList object contains key H? = " + sortedList.ContainsKey("H")); 
    } 
}

ผลลัพธ์

จะได้ผลลัพธ์ดังนี้:

SortedList elements... 
Key = A, Value = 1 
Key = B, Value = 2 
Key = C, Value = 3 
Key = D, Value = 4 
Key = E, Value = 5 
Key = F, Value = 6 
Key = G, Value = 7 
Key = H, Value = 8 
Key = I, Value = 9 
Key = J, Value = 10 
Count of SortedList key-value pairs = 10 
Enumerator to iterate through the SortedList... 
Key = A, Value = 1 
Key = B, Value = 2 
Key = C, Value = 3 
Key = D, Value = 4 
Key = E, Value = 5 
Key = F, Value = 6 
Key = G, Value = 7 
Key = H, Value = 8 
Key = I, Value = 9 
Key = J, Value = 10 
Does the SortedList object contains key M? = False 
Does the SortedList object contains key H? = True
