What to do with caught exception

Question

When the WCF service is disabled, I will catch this exception like this.

   public List<ProjektyEntity> GetProjekty()
   {
      try
      {
         return this.channel.GetProjekty();
       }
       catch (EndpointNotFoundException exception)
       {
          //what to do at this point ?
       }
    }

But I do not know what to do in the catch block. I can only return an object of the type List<ProjektyEntity>I would like to write a message to the user, something like "Service is disabled" My Presentation Level is ASP.NET MVC. Is there any strategy for such situations?

There is a simple rule: if you do not know how to handle the exception, do not understand it.

Answer 5

An exception is not intended to be caught and handled in this context. It needs to be processed at a much higher level, having access to any console as a whole.

The best you can do here is simply to register the exception with the necessary details and restore correctly.

Answer 6

Create an exception object with sufficient debugging granularity and call the call method

 public List<ProjektyEntity> GetProjekty()
   {
      try
      {
         return this.channel.GetProjekty();
       }
       catch (EndpointNotFoundException exception)
       {
          'Write here Some Clean Up Codes
          ' Log it somewhere on your server so that you can fix the error

       }
    }
