i have this class: 

   class Article
    {
            public int Id { get; set; }
            public string Name { get; set; }
    }


    List<Article> arts = new List<Article>();

I have a list of objects. These objects have two variables ID, Name. I need to check if in this list there is an article with name = "Cheese". How can I do to make this search returns a Boolean value? Any help would be great! Thanks!

bool hasCheese = arts.Any(a => a.Name == "Cheese");

简单的： - 

bool contains = arts.Any(x => x.Name == "Cheese");

Any将返回一个布尔值，指示列表是否包含Cheese
