I defined an interface which has an event and a property defined as follows.
public interface IMyInterface
{
event EventHandler SomeEvent;
string GetName();
string IpAddress { get; set; }
}
I then created a class and using it, every thing works fine.
Now I want to extend this class using a decorator. I am not sure how to handle the event. For the property I think I am clear, just want confirmation.
I defined the decorator class as follows.
public class LoggerDecorator : IMyInterface
{
private readonly IMyInterface _MyInterface;
private readonly ILog _MyLog;
public LoggerDecorator(IMyInterface myInterface, ILog myLog)
{
if (myInterface == null)
throw new ArgumentNullException("IMyInterface is null");
_MyInterface = myInterface;
if (myLog == null)
throw new ArgumentNullException("ILog instance is null");
_MyLog = myLog;
}
public string GetName()
{
// If needed I can use log here
_MyLog.Info("GetName method is called.");
return _MyInterface.GetName();
}
// Is this the way to set properties?
public string IpAddress
{
get
{
return _MyInterface.IpAddress;
}
set
{
// If needed I can use log here
_MyLog.Info("IpAddress is set.");
_MyInterface.IpAddress = value;
}
}
// But How to handle this evetn?? Please help. I am not clear about this.
public event EventHandler SomeEvent;
}
