在MatchCollection上使用LINQ扩展方法语法
问题描述:
我有以下代码:
MatchCollection matches = myRegEx.Matches(content);
bool result = (from Match m in matches
where m.Groups["name"].Value.Length > 128
select m).Any();
是否可以使用LINQ扩展方法语法来做到这一点?
Is there a way to do this using the LINQ extension method syntax?
像这样的东西:
bool result = matches.Any(x => ... );
答
using System.Linq;
matches.Cast<Match>().Any(x => x.Groups["name"].Value.Length > 128)
您只需要将其从 IEnumerable
转换为 IEnumerable< Match>
(IEnumerable< T>)来访问IEnumerable< T>上提供的LINQ扩展。
You just need to convert it from an IEnumerable
to an IEnumerable<Match>
(IEnumerable<T>) to get access to the LINQ extension provided on IEnumerable<T>.
