How to validate data using regex?

See if the code below helps

        static string[] testData = {"D[123] = string[] { \"Product A\", \"$230\" };",
                             "D[125] = string[] { \"Product B\", \"$30\" };",
                             "D[126] = string[] { \"Product C\", \"$50\" };"};
        static void Main(string[] args)
        {
            Regex expr = new Regex(".*\\[(.*)\\]\\s*=.*\"(.*)\".*\"(.*)\" ");
            foreach (string test in testData)
            {
                MatchCollection matches = expr.Matches(test);
                string param1 = matches[0].Groups[1].ToString();
                string param2 = matches[0].Groups[2].ToString();
                string param3 = matches[0].Groups[3].ToString();
            }
