Please find below my code. Employee class implements IEmployee interface.
namespace MiddleWare.ServiceContracts
{
[ServiceContract(Namespace = "http://mywebsite.com/MyProject")]
public interface IMiscellaneous
{
[OperationContract]
[ServiceKnownType(typeof(MiddleWare.Classes.Employee))]
IEnumerable<IEmployee> Search_Employee
(string SearchText);
}
namespace MiddleWare.ServiceClasses
{
public class Miscellaneous : IMiscellaneous
{
public IEnumerable<IEmployee> Search_Employee
(string SearchText)
{
List<IEmployee> emp = new List<IEmployee>();
IEmployee TempObject = (IEmployee)Activator.CreateInstance(typeof(IEmployee));
TempObject.EmployeeId = "12345678";
emp.Add(TempObject);
return emp;
}
}
}
As is visible the above code does compile but wont work because interface instance cannot be created.How can I achive DI(Dependency Injection) here...If I write..
IEmployee TempObject = (IEmployee)Activator.CreateInstance(typeof(Employee));
Then this class will be dependent not only on the Interface but also the class...assuming that one fine day Employee class becomes Employee2.There will be code changes at two places..
1)[ServiceKnownType(typeof(MiddleWare.Classes.Employee2))]
2)IEmployee TempObject = (IEmployee)Activator.CreateInstance(typeof(Employee2));
I want to avoid that. Can we do something at implementation of IOperationBehavior or is there a Ninject way of achieving this or am I trying to achieve impossible?
