我怎样才能将部分 url 与 c#

Question

我有一个动态列表，如下几行

https://www.example.com/*/post/

https://www.example2.com/videos/*

https://www.example3.com/photo/

我如何匹配 C# 以下 url（返回 true）

https://www.example.com/user123/post/

http://www.example.com/user123/post/abc

https://www.example2.com/videos/1234

https://www.example2.com/videos/1234/5678

http://www.example2.com/videos/1234/5678

http://example2.com/videos/1234/video.asp?id=1

也许我可以使用 UriTemplate 但 url 有很多部分。他们没有静态格式。

试试这个使用正则表达式的方法：static void Main(string[] args){  var urls = new string[] { "https://www.example.com/*/post/", "https://www.example2.com/videos/*" };  // here regex patterns are created: special characters are escaped and   // star, which means here "anything" is replaced by .+ which means "one or more of any charaters"  var regexes = urls.Select(url => new Regex(url.Replace("/", @"\/").Replace(".", @"\.").Replace("*", ".+")));  var toCheck = new string[]  {  "https://www.example.com/user123/post/",  "http://www.example.com/user123/post/abc",  "https://www.example2.com/videos/1234",  "https://www.example2.com/videos/1234/5678",  "http://www.example2.com/videos/1234/5678",  "http://example2.com/videos/1234/video.asp?id=1"  };  var valid = toCheck.Where(url => regexes.Where(r => r.Match(url).Success).Any()).ToArray();}
