基本上我想从上面提取99978f1c-4c04-41ac-abcb-5039658a1f52值。

请尝试这个
// specify Regular expression
Regex pageParser = new Regex(@"href=[""|']https://abc-api-test.mywebsites.net:443/#/userreg/(?<ID>['S]*?)[""|']", RegexOptions.IgnoreCase | RegexOptions.Multiline);
// extract matches from your HTML
MatchCollection matches = pageParser.Matches(yourHtml);
//Iterate through each match
foreach (var m in matches)
{
var id = m.Groups["ID"].Value;
// do whatever you want with the ID
}
