如何通过移动电话号码了解移动运营商

How to know the Mobile Operator with the mobile Number

推荐答案

据我所知，每个公司运营商都保留了最初的4个号码.因此您可以使用表格将号码和操作员名称存储在数据库中，然后根据需要使用.
此示例的用法是:

As per my knowledge initial 4 number are reserved for each company operator.so u can use a table to store number and operator name in your Database and then use according to your requirement.
a sample use of this is:

Console.WriteLine("Enter mobile number with Country code");
          string r = Console.ReadLine().Substring(0,4);
          Console.WriteLine(r);
          switch(r)
          {
              case "8050":
                  Console.WriteLine("Docomo");
                  break;
              case "9216":
                  Console.WriteLine("Hutch");
                  break;
              case "8020":
                  Console.WriteLine("Vodaphone");
                  break;
              default:
                  Console.WriteLine("Not in use");
                  break;
          }
          Console.ReadLine();
