C# C:在数组中搜索

我有一个存储dvd和蓝光的dvd应用程序，我想通过director搜索阵列。下面是inventory类的代码，我看到了许多不同的方法。似乎有一些争论认为这是实现这一目标的最佳/最有效的方法，有什么建议吗

    namespace MovieInventoryApplication

}最容易使用Linq的imho是：

string director = "Alfred Hitchcock";
IEnumerable<DVD> dvds = DVDMovies.Where(dvd => dvd.Director == director);
IEnumerable<DVD> blueRays = BlurayMovies.Where(br => br.Director == director);
List<DVD> allMatches = new List<DVD>();
allMatches.AddRange(dvds.Concat(blueRays));

我认为你的设计有缺陷

DVD和BluRay课程实际上应该是：

具有类型属性的单个类，可能是包含DVD和BluRay的枚举。这样，在几年内，一旦您获得了一种新媒体，您只需向Enum添加一个值，您的应用程序将是最新的。 两个不同的类实现了一个自定义接口，您可以调用，比如说，IMedia。 另外，我强烈建议您利用C中的List对象，而不是数组。它非常快速，您可以轻松添加/删除项目，而无需调整阵列大小

以下是关于Linq的一节课：

下面是我创建媒体类的方法：

public class Media
{
    public enum MediaType
    {
        DVD,
        Bluray
    }

    public MediaType TypeOfMedia { get; set; }
    public string Director { get; set; }
    public string Title { get; set; }

    public Media(string Title, string Director, MediaType TypeOfMedia)
    {
        this.TypeOfMedia = TypeOfMedia;
        this.Director = Director;
        this.Title = Title;
    }
}

下面是一个如何使用它的示例：

        List<Media> data = new List<Media>();

        results.Add(new Media("Movie 1", "John D", Media.MediaType.DVD));
        results.Add(new Media("Movie 2", "John D", Media.MediaType.DVD));
        results.Add(new Media("Movie 3", "SomeOtherDirector", Media.MediaType.Bluray));
        results.Add(new Media("Movie 4", "John D", Media.MediaType.Bluray));

        IEnumerable<Media> listDirectors = from media in data
                                           where media.Director == "John D"
                                           select media;

        foreach (Media media in listDirectors)
            Console.WriteLine(media.Title);

另一个示例是，列表DVD和列表Bluray函数实际上可以是一个函数：

    private void ListMediaByType(List<Media> data, Media.MediaType type)
    {
        foreach (Media media in data.Where(media => media.TypeOfMedia == type))
            Console.WriteLine(media.Title);
    }

如您所见，这些技术大大简化了查询：

争论是什么？您尝试过什么？比如results=Array.FindAllarr、s=>s.Equalstarget或bool has=arr.Containsvar。我见过很多不同的WaySTime，不幸的是，他使用的是两个不同的类DVD和Bluray-我不认为你可以从Bluray数组生成IEnum。我意识到列表更有意义，但我会坚持使用array@Joe：代码有点混乱，但他只使用了一类DVD。您必须查看AddXYZ方法。@JonathanOberhaus：您没有提到结果集合也应该是数组。但它很简单：DVD，ConcatBlueray，ToArray，哦，真的。不过，这是无法维护的代码，因此我建议增强DVD类以包含任何类型的媒体。顺便说一下，使用阵列也可以实现上述所有功能！在ListMediaByType中，可以随意将列表更改为Media[]。
