how to write this code?

I need to write a code for a form I created called newmembers that takes string,int,string but i did not know how to write the class for it in the app_code

public class newmember
 {
     public static string Register(string mname, int password, string email)
     {
         SqlConnection con = new SqlConnection(Database.ConnectionString);
         try







 }

maybe i should add that the function of the method is to take these values and add them to a table in the database called members.
