using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args){
      List<string> list1 = new List<string>();
      list1.Add("One");
      list1.Add("Two");
      list1.Add("Three");
      list1.Add("Four");
      list1.Add("Five");
      Console.WriteLine("Elements in List1...");
      foreach (string res in list1){
         Console.WriteLine(res);
      }
      Console.WriteLine("Capacity of List1 = "+list1.Capacity);
      List<string> list2 = new List<string>();
      list2.Add("India");
      list2.Add("US");
      list2.Add("UK");
      list2.Add("Canada");
      list2.Add("Poland");
      list2.Add("Netherlands");
      Console.WriteLine("Elements in List2...");
      foreach (string res in list2){
         Console.WriteLine(res);
      }
      Console.WriteLine("Capacity of List2 = "+list2.Capacity);
      Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1));
   }
}

输出

这将产生以下输出 −

Elements in List1...
One
Two
Three
Four
Five
Capacity of List1 = 8
Elements in List2...
India
US
UK
Canada
Poland
Netherlands Capacity of List2 = 8
Is List2 equal to List1? = False

示例

我们现在来看另一个示例 −

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args){
      List<string> list = new List<string>();
      list.Add("One");
      list.Add("Two");
      list.Add("Three");
      list.Add("Four");
      list.Add("Five");
      Console.WriteLine("Elements in List1...");
      foreach (string res in list){
         Console.WriteLine(res);
      }
      Console.WriteLine("
Count of elements in list = "+list.Count);       Console.WriteLine("Capacity of List (updated) = "+list.Capacity);       list.Clear();       Console.WriteLine("
Count of elements in list (updated) = "+list.Count);       Console.WriteLine("Capacity of List now = "+list.Capacity);    } }

输出

这将产生以下输出 −

Elements in List1...
One
Two
Three
Four
Five
Count of elements in list = 5
Capacity of List (updated) = 8
Count of elements in list (updated) = 0 Capacity of List now = 8
