Answer 1

You can try this;

Firstly, you should edit your myclass like this;

[DataContract]
public class myclass
{

    [DataMember]
    public string CompanyCode { get; set; }

    [DataMember]
    public string Username { get; set; }

    [DataMember]
    public string Password { get; set; }
}

then your interface like this;

 [ServiceContract]
public interface ICustProfileService
{
    [OperationContract]
    string SaveCorporateProfile(myclass dt);
}

And you implement your .svc file for using this interface

 public class CustProfileService: ICustProfileService
{
  [WebInvoke(Method = "POST",UriTemplate = "/SaveCorporateProfile?dt={dt}"
   BodyStyle = WebMessageBodyStyle.Bare,
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json)]

    public string SaveCorporateProfile(myclass dt)
    {          

        return "success";
    }

}
