Calling interface method C#

Question

I am developing an ASP.net MVC application and I have a controller ExceptionController for displaying exceptions caught in my application.

This controller implements an interface IExceptionLogger

public class ExceptionController : Controller, IExceptionLogger
  {...}

which has one method void LogException(ExceptionDetail exceptionDetail);

I have implemented the method inside the ExceptionController too.

void IExceptionLogger.LogException(ExceptionDetail exceptionDetail)
 {...}

Now I need to call the method LogException() from the action Index of the ExceptionController.

public ActionResult Index(ExceptionDetail exceptionDetail)
    {
      // Method must be called here
      return View(exceptionDetail);
    }

How can I do this?

Because LogException is implemented explicitly, you have to cast to IExceptionLogger before calling it:

public ActionResult Index(ExceptionDetail exceptionDetail)
{
    ((IExceptionLogger)exceptionDetail).LogException();

     return View(exceptionDetail);
}

To make it work without casting, implement method implicitly:

void LogException(ExceptionDetail exceptionDetail)
{
}
