c# - Error Ambiguity and Missing partial modifier -

-

i follow http://www.dotnetcurry.com/showarticle.aspx?id=585 project have error ambiguity , missing partial modifier.

my code @ iservice1.cs

namespace wct_dataserviceapp {     [servicecontract]     public interface iservice1     {         [operationcontract]         imageemployee getempbyempno(int empno);     }      [datacontract]     public class imageemployee     {         [datamember]         public int empno { get; set; }         [datamember]         public byte[] empimage { get; set; }     } }

and code @ service1.svc.cs

namespace wct_dataserviceapp {     // note: can use "rename" command on "refactor" menu change class name "service1" in code, svc , config file together.     public class service1 : iservice1     {         public imageemployee getempbyempno(int empno)         {             var conn = new sqlconnection(@"data source=yeo-pc\sqlexpress;initial catalog=image;integrated security=true");             conn.open();             var cmd = new sqlcommand();             cmd.connection = conn;             cmd.commandtext = "select * imageemployee empno=@empno";             cmd.parameters.addwithvalue("@empno", empno);              var reader = cmd.executereader();              imageemployee objimgemp = new imageemployee();              while (reader.read())             {                 objimgemp.empno = convert.toint32(reader["empno"]);                 objimgemp.empimage = (byte[])reader["empimage"];             }             reader.close();             conn.close();             return objimgemp;         }     } }

it appears has class service1 in solution. if trying in new wcf project default 2 files 1 interface , 1 class, named as: iservice1.cs , service1.cs. need delete these 2 or replace code yours. error asking use word partial, used partial class assuming defining partial class service1 in new code file.
