C# regex capturing only the whole expression and not the individual capture groups

Question

I have this regex to capture type names- first the type name, then the list of generic parameters, and finally the assembly name:

(.*?)\[\[(.*?)\]\], (.*)

And when I run it against a string like this (a simplified version of the fully qualified name of a type):

System.Collections.Generic.List`1[[FrEee.Modding.Formula`1[[System.String, mscorlib]], FrEee.Core]], mscorlib

I get only one match on the whole string:

Why are the three capture groups I defined not matching the individual parts of the string?

Answer 1

I was using this code to access the captures:

match.Captures[1].Value

When I should have used:

match.Groups[1].Captures[0].Value

Answer 2

另外，看起来您应该使参数通配符贪婪，以便它不会出现在内括号上：

(?<type>.*?)\[\[(?<parameters>.*)\]\], (?<assembly>.*)
