c# - 如何将 System.Linq.Enumerable.WhereListIterator<int> 转换为 List<int>？

Question

在下面的示例中，我如何轻松转换 eventScores至 List<int>这样我就可以将它用作 prettyPrint 的参数？

Console.WriteLine("Example of LINQ's Where:");
List<int> scores = new List<int> { 1,2,3,4,5,6,7,8 };
var evenScores = scores.Where(i => i % 2 == 0);

Action<List<int>, string> prettyPrint = (list, title) =>
    {
        Console.WriteLine("*** {0} ***", title);
        list.ForEach(i => Console.WriteLine(i));
    };

scores.ForEach(i => Console.WriteLine(i));
prettyPrint(scores, "The Scores:");
foreach (int score in evenScores) { Console.WriteLine(score); }

您将使用 ToList 扩展:

var evenScores = scores.Where(i => i % 2 == 0).ToList();
