Not getting desired string in regex groups

My example is working fine with greedy when I use to capture the whole value of a string and a group(in group[1] ONLY) enclose with a pair of single quote
But when I want to capture the whole value of a string and a group(in group[1] ONLY) enclose with multiple pair of single quote , it only capture the value of string enclose with last pair but not the string between first and last single quotes.

What I have tried:

string val1 = "Content:abc'23'asad";          //--->23
            string val2 = "Content:'Scale['#13212']'ta";

            Match match1 = Regex.Match(val1, @".*'(.*)'.*");
            Match match2 = Regex.Match(val2, @".*'(.*)'.*");
            if (match1.Success)
            {
                string value1 = match1.Value;
                string GroupValue1 = match1.Groups[1].Value;
                Console.WriteLine(value1);
                Console.WriteLine(GroupValue1);

                string value2 = match2.Value;
                string GroupValue2 = match2.Groups[1].Value;
                Console.WriteLine(value2);
                Console.WriteLine(GroupValue2);

                Console.ReadLine();

                // using greedy For val1 i am getting perfect value for-
                // value1--->Content:abc'23'asad
                // GroupValue1--->23

                // BUT using greedy For val2 i am getting the string elcosed by last single quote-
                // value2--->Content:'Scale['#13212']'ta
                // GroupValue2---> ]
                // But i want GroupValue2--->Scale['#13212']
            }
