如何总结C＃集合中字段的值

Question

I have the following class: 我有以下课程：

public class ViewEvent {

    public long Elapsed { get; private set; }
    public string Description { get; private set; }

}

In my model I have a collection of instances of these classes: 在我的模型中，我收集了这些类的实例：

public IList<ViewEvent> Events { get; set; }

How can I get the total elapsedTime of all the ViewEvents in my Events collection? 如何获取事件集中所有ViewEvent的总经过时间？

Answer 1

With LINQ, Events.Sum(event => event.Elapsed); 使用LINQ， Events.Sum(event => event.Elapsed); . 。

As pointed out by Habib, be sure to add 正如哈比卜指出的那样，请务必添加

using System.Linq;
