Hi,

I have an interface for logging the exceptions, i.e. IExceptionLogger.

This interface has 3 implementations: DBExceptionLogger, XMLExceptionLogger, CSVExceptionLogger.

I have an application that will make a use of DBExceptionLogger.

The application references only IExceptionLogger. How do I create an instance of DBExceptionLogger within the application.

I can't reference the DBExceptionLogger directly since it will break the purpose of having IExceptionLogger interface.

Thanks

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
