Key-based I/O Collection ใน C# คือ SortedList<TKey, TValue>
SortedList = Key-Value Pairs เรียงตาม Key เข้าถึงได้ทั้ง Key และ Index
s.Add("Sub1", "Physics");
s.Add("Sub2", "Chemistry");
s.Add("Sub3", "Biology");
s.Add("Sub4", "Java");
ตัวอย่าง
using System;
using System.Collections;
namespace Demo
{
class Program
{
static void Main(string[] args)
{
SortedList s = new SortedList();
s.Add("Sub1", "Economics");
s.Add("Sub2", "Accountancy");
s.Add("Sub3", "Business Studies");
s.Add("Sub4", "English");
Console.WriteLine("Capacity = " + s.Capacity);
ICollection key = s.Keys;
foreach (string k in key) Console.WriteLine(k + ": " + s[k]);
}
}
}
Output
Capacity = 16 Sub1: Economics Sub2: Accountancy Sub3: Business Studies Sub4: English
