C#中列表的容量
为了获得列表的容量，代码如下-
示例
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));
}
}输出结果
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
现在让我们来看另一个示例-
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("\nCount of elements in list = "+list.Count);
Console.WriteLine("Capacity of List (updated) = "+list.Capacity);
list.Clear();
Console.WriteLine("\nCount of elements in list (updated) = "+list.Count);
Console.WriteLine("Capacity of List now = "+list.Capacity);
}
}输出结果
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
