关于C#泛型列表ListT的基本用法总结

示例代码如下：namespace SampleListT{ class Program { static void Main(string[] args) {//using System.Collections.Generic; 命名空间中的List<T>//using System.Collections;　命名空间中的ArrayList //都实现了列表集合，一个是泛形集合，一个是非泛型的//下面我们将Person对象加到集合中 Person p1 = new Person( “aladdin” , 20 );Person p2 = new Person(“zha

This code creates a new ArrayList instance using the generic type parameter `<E>` provided by the `List` interface in the Apache Commons Collections library. The `newArrayList<>()` method initializes the ArrayList with an initial capacity of 10. This method is useful when you want to create a new ArrayList instance and populate it with elements in a single step. For example: ``` List<String> myList = Lists.newArrayList("apple", "banana", "orange"); ``` This creates a new ArrayList of Strings and populates it with the elements "apple", "banana", and "orange".
