如果集合包含满足谓词的元素，LINQ将返回true

我想简化语法。我想我能用吗？或但是我不太明白怎么做。

你可以用。比如说

public bool AnyBroken => (Statuses != null) && Statuses.Count(s => s == Status.Broken) > 0;

您可以尝试这种方式，链接为实时演示

请注意：

但是如果status为null呢？status？将返回null，该值不等于true。因此，任何损坏的都将被评估为false。

public bool AnyBroken => (Statuses != null) && Statuses.Count(s => s == Status.Broken) > 0;

public bool AnyBroken => Statuses?.Any(x=>x == Status.Broken)==true;

using System;
using System.Linq;

public class Program
{
    public static void Main()
    {
        var listContainBroken = new [] { Status.Broken,  Status.Unspecified }; 
        var listDoesNotContainBroken = new [] { Status.Unspecified }; 

        Console.WriteLine("List Contain Broken: " + listContainBroken?.Any(s => s == Status.Broken));
        Console.WriteLine("List Does not Contain Broken: " + listDoesNotContainBroken?.Any(s => s == Status.Broken));
    }

    public enum Status
    {
      Unspecified = 0,
      Good = 1,
      Broken = 2
    }
}
