本文介绍了如何System.Linq.Enumerable.WhereListIterator<转换,诠释>列出< INT> ;?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在下面的例子中,我怎么能轻易转换 eventScores
到列表< INT>
,这样我可以使用它作为 prettyPrint
?
参数
Console.WriteLine(示例LINQ的公司在哪里:);
名单,LT; INT>分数=新的List< INT> {1,2,3,4,5,6,7,8};
变种evenScores = scores.Where(ⅰ= I标记%2 == 0);
动作<名单,LT; INT>中串> prettyPrint =(列表标题)=>
{
Console.WriteLine(*** {0} ***称号);
list.ForEach(ⅰ= GT; Console.WriteLine(ⅰ));
};
scores.ForEach(ⅰ= GT; Console.WriteLine(ⅰ));
prettyPrint(成绩的成绩:);
的foreach(在evenScores INT得分){Console.WriteLine(分); }
解决方案
您最好使用了ToList扩展:
VAR evenScores = scores.Where(I = I标记%2 == 0).ToList();
In the below example, how can I easily convert eventScores
to List<int>
so that I can use it as a parameter for prettyPrint
?
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); }
解决方案
You'd use the ToList extension:
var evenScores = scores.Where(i => i % 2 == 0).ToList();
