C#list<T>类用于存储和获取元素。它可以有重复的元素。它位于System.Collections.Generic命名空间中。
C# List<T> example
让无涯教程看一个泛型List<T>类的示例，该类使用add()方法存储元素，并使用for-each循环迭代列表。
using System;
using System.Collections.Generic;
public class ListExample
{
public static void Main(string[] args)
{
// Create a list of strings
var names = new List();
names.Add("Sonoo Jaiswal");
names.Add("Ankit");
names.Add("Peter");
names.Add("Irfan");
</span><span class="com">// Iterate list element using foreach loop</span><span class="pln">
</span><span class="kwd">foreach</span><span class="pln"> </span><span class="pun">(</span><span class="kwd">var</span><span class="pln"> name </span><span class="kwd">in</span><span class="pln"> names</span><span class="pun">)</span><span class="pln">
</span><span class="pun">{</span><span class="pln">
</span><span class="typ">Console</span><span class="pun">.</span><span class="typ">WriteLine</span><span class="pun">(</span><span class="pln">name</span><span class="pun">);</span><span class="pln">
</span><span class="pun">}</span><span class="pln">
</span><span class="pun">}</span><span class="pln">
}
输出：
Sonoo Jaiswal Ankit Peter Irfan
C# List<T> 使用集合初始化器的示例
using System;
using System.Collections.Generic;
public class ListExample
{
public static void Main(string[] args)
{
// Create a list of strings using collection initializer
var names = new List() {"Sonoo", "Vimal", "Ratan", "Love" };
</span><span class="com">// Iterate through the list.</span><span class="pln">
</span><span class="kwd">foreach</span><span class="pln"> </span><span class="pun">(</span><span class="kwd">var</span><span class="pln"> name </span><span class="kwd">in</span><span class="pln"> names</span><span class="pun">)</span><span class="pln">
</span><span class="pun">{</span><span class="pln">
</span><span class="typ">Console</span><span class="pun">.</span><span class="typ">WriteLine</span><span class="pun">(</span><span class="pln">name</span><span class="pun">);</span><span class="pln">
</span><span class="pun">}</span><span class="pln">
</span><span class="pun">}</span><span class="pln">
}
输出：
Sonoo Vimal Ratan Love
