c# - Consuming WCF service in Windows Forms application -

i consuming wcf service in windows forms application. wcf service has 2 classes called fulltimeemployee , parttimeemployee. want register users based on employee type. user type come emu. when click submit button, message:

please select employee type

as shown in screen shot.

here code form class..

 [knowntype(typeof(fulltimeemployee))]     [knowntype(typeof(parttimeemployee))]     [datacontract(namespace = "http://pragimtech.com/employee")]     public class employee     {         private int _id;         private string _name;         private string _gender;         private datetime _dateofbirth;          [datamember(order = 1)]         public int id         {             { return _id; }             set { _id = value; }         }          [datamember(order = 2)]         public string name         {             { return _name; }             set { _name = value; }         }          [datamember(order = 3)]         public string gender         {             { return _gender; }             set { _gender = value; }         }          [datamember(order = 4)]         public datetime dateofbirth         {             { return _dateofbirth; }             set { _dateofbirth = value; }         }          [datamember(order = 5)]         public employeetype type { get; set; }     }      public enum employeetype     {         fulltimeemployee = 1,         parttimeemployee = 2     } } 

here wcf service code register employee based on type:

public void saveemployee(employee employee) {     string cs = configurationmanager.connectionstrings["dbcs"].connectionstring;      using (sqlconnection con = new sqlconnection(cs))     {         sqlcommand cmd = new sqlcommand("spsaveemployee", con);         cmd.commandtype = commandtype.storedprocedure;          sqlparameter parameterid = new sqlparameter                 {                     parametername = "@id",                     value = employee.id                 };         cmd.parameters.add(parameterid);          sqlparameter parametername = new sqlparameter                 {                     parametername = "@name",                     value = employee.name                 };         cmd.parameters.add(parametername);          sqlparameter parametergender = new sqlparameter                 {                     parametername = "@gender",                     value = employee.gender                 };         cmd.parameters.add(parametergender);          sqlparameter parameterdateofbirth = new sqlparameter                 {                     parametername = "@dateofbirth",                     value = employee.dateofbirth                 };         cmd.parameters.add(parameterdateofbirth);          sqlparameter parameteremployeetype = new sqlparameter                 {                     parametername = "@employeetype",                     value = employee.type                 };         cmd.parameters.add(parameteremployeetype);          if (employee.gettype() == typeof(fulltimeemployee))         {             sqlparameter parameterannualsalary = new sqlparameter                     {                         parametername = "@annualsalary",                         value = ((fulltimeemployee)employee).annualsalary                     };             cmd.parameters.add(parameterannualsalary);         }         else         {             sqlparameter parameterhourlypay = new sqlparameter                     {                         parametername = "@hourlypay",                         value = ((parttimeemployee)employee).hourlypay,                     };             cmd.parameters.add(parameterhourlypay);              sqlparameter parameterhoursworked = new sqlparameter                     {                         parametername = "@hoursworked",                         value = ((parttimeemployee)employee).hoursworked                     };             cmd.parameters.add(parameterhoursworked);         }          con.open();         cmd.executenonquery();     } } 

here windows form application code:

when click submit button shows

please select employee type

and not insert new employee sql server database..
