Linq - 从List中获取相同类型的两个元素之间的元素组

Question

说我有以下网址列表：

Url 1:  https://www.example.com/dummy-path1?<query-params-here>
Url 2:  https://www.example.com/dummy-path2?<query-params-here>
Url 3:  https://www.example.com/specific-path?<query-params-here>
Url 4:  https://www.example.com/path1?<query-params-here>
Url 5:  https://www.example.com/path2?<query-params-here>
Url 6:  https://www.example.com/specific-path?<query-params-here>
Url 7:  https://www.example.com/path1?<query-params-here>
Url 8:  https://www.example.com/path2?<query-params-here>
...

我想采取一组元素，以便最终我会：

Group1:
Url 3:  https://www.example.com/specific-path?<query-params-here>
Url 4:  https://www.example.com/path1?<query-params-here>
Url 5:  https://www.example.com/path2?<query-params-here>

Group2:
Url 6:  https://www.example.com/specific-path?<query-params-here>
Url 7:  https://www.example.com/path1?<query-params-here>
Url 8:  https://www.example.com/path2?<query-params-here>

注意：两个组没有必要具有相同数量的项目。

我尝试了SkipWhile和TakeWhile的几个LINQ组合：

var a = lines.SkipWhile(s => !s.Contains("example.com/specific-path"));

但是当我尝试应用TakeWhile(s => s.Contains("example.com/specific-path"))时，它会失败，因为第一个元素（SkipWhile之后）已经包含specific-path。

如何使用LINQ实现此目的？

可以使用MoreLinq.Segment：

完成此操作

navigated.Segment(x => x.StartsWith("https://www.example.com/specific-path"));

var source = @"Url 1:  https://www.example.com/dummy-path1?<query-params-here>
Url 2:  https://www.example.com/dummy-path2?<query-params-here>
Url 3:  https://www.example.com/specific-path?<query-params-here>
Url 4:  https://www.example.com/path1?<query-params-here>
Url 5:  https://www.example.com/path2?<query-params-here>
Url 6:  https://www.example.com/specific-path?<query-params-here>
Url 7:  https://www.example.com/path1?<query-params-here>
Url 8:  https://www.example.com/path2?<query-params-here>";

var navigated = Regex.Matches(source, "https.+")
    .Cast<Match>()
    .Select(x => x.Value);

navigated
    .Segment(x => x.StartsWith("https://www.example.com/specific-path"))
    .Where(x => x.First().StartsWith("https://www.example.com/specific-path")) // skip first group that contains dummy path
    .Dump();

结果：
