我有一個動態列表，如下幾行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/abchttps://www.example2.com/videos/1234https://www.example2.com/videos/1234/5678http://www.example2.com/videos/1234/5678http://example2.com/videos/1234/video.asp?id=1也許我可以使用 UriTemplate 但 url 有很多部分。他們沒有靜態格式。

試試這個使用正則表達式的方法：
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();
}
