高分求教！c#如何将字符串转换为数组？

            string a="a:3:{i:0;a:3:{i:0;s:4:\"dfdf\";i:1;s:4:\"dsfg\";i:2;s:4:\"gfgg\";}"

                +"i:1;a:3:{i:0;s:3:\"jkj\";i:1;s:2:\"jj\";i:2;s:3:\"ffg\";}"

                +"i:2;a:3:{i:0;s:3:\"sdd\";i:1;s:5:\"dfsdf\";i:2;s:4:\"gfgh\";}}";



            string[] str1 = System.Text.RegularExpressions.Regex.Split(a.Substring(0,a.Length-3), ";}");

            

            Console.WriteLine(str1.Length);//这里就可以得出有几组数据。

                                          //如string[][] t = new string[3][];

         

            foreach (string i in str1)

            {

                string tmp = "\"" + i;

             

                string[] str2 = System.Text.RegularExpressions.Regex.Split(tmp, "\"[^\"]*\"");

                int l2 = str2.Length;                       



                foreach (string j in str2)

                {

                      Console.WriteLine(j);  //输出多了一个空字符串，你可以处理一下                 

                }

                

            }

  string a=":{i:0;a:3:{i:0;s:4:\"dfdf\";i:1;s:4:\"dsfg\";i:2;s:4:\"gfgg\";}";

            while (a.IndexOf("\"")!=-1)

            {

                a = a.Substring(a.IndexOf("\""));

                

                int i = a.IndexOf("\"",1);

                string b = a.Substring(1, i - 1);

                Console.WriteLine(b);//这就是想要的吧？

                a = a.Substring(i+1);

               

            }
