[RESOLVED] HttpException not handled

[stephsh]

Interesting, I have never seen that type of structure before. Could you explain it please?

[nelo]

private Type[] _arrayOfTypes = new Type[]
  { 
      typeof(IndexOutOfRangeException), 
      typeof(HttpException)
   };

Type is just a class in the .NET framework...

What's happening here is that I'm using the collection initializer construct from C#3.0/.NET 3.5. It enables me to create the array with the elements I need in a single statement.

The verbose alternative would have been something like this...

Type[] _arrayOfTypes = new Type[2];
_arrayOfTypes[0] = typeof(IndexOutOfRangeException);
_arrayOfTypes[1] = typeof(HttpException);

Well in terms of lines of code it is pretty much the same. I just like to use the new language features when I have the opportunity.

Edit: I would like to put a disclaimer here to say that I'm aware that C#3.0 isn't exactly new...

That makes more sense to me, thanks! I rewrote my ErrorClass using the code you gave me and I took out the error msgs which dont really concern the user. The question is how do I retrieve the error message type so that I can check it against the array?

 // Create an array of types
        protected Type[] _arrayOfTypes = new Type[]
        {
            typeof(HttpException),
            typeof(UnauthorizedAccessException),
            typeof(FileNotFoundException),
            typeof(IOException),
            typeof(IndexOutOfRangeException),
            typeof(NullReferenceException)
        };

        // This is a different way for doing:
        #region Old method
        //protected void GetArray()
        //{
        //    _arrayOfTypes[0] = typeof(IndexOutOfRangeException);
        //    _arrayOfTypes[1] = typeof(HttpException);
        //}

        // where
        //protected Type[] _arrayOfTypes = new Type[2];
        #endregion

        public string GetErrorMsg(Type sError)
        {
            if (sError == _arrayOfTypes[0])
            {
                sMsgErr = "Zugang zur Seite nicht erlaubt.";
            }
            else if (sError == _arrayOfTypes[1])
            {
                sMsgErr = "Zugang nicht erlaubt.";
            }
            else if (sError == _arrayOfTypes[2])
            {
                sMsgErr = "Die Datei wurde nicht gefunden.";
            }
            else if (sError == _arrayOfTypes[3])
            {
                sMsgErr = "Ein E/A-Fehler ist auftritten.";
            }
            else if (sError == _arrayOfTypes[4])
            {
                sMsgErr = "Die Angegebene ID existiert nicht.";
            }
            else
            {
                sMsgErr = "Ein Fehler ist aufgetreten.";
            }

            return sMsgErr;
        }

Sorry I meant:

 // Create an array of types
        protected Type[] _arrayOfTypes = new Type[]
        {
            typeof(HttpException),
            typeof(UnauthorizedAccessException),
            typeof(FileNotFoundException),
            typeof(IOException),
            typeof(IndexOutOfRangeException)
        };

        public string GetErrorMsg(Type sError)
        {
            if (sError == _arrayOfTypes[0])
            {
                sMsgErr = "Zugang zur Seite nicht erlaubt.";
            }
            else if (sError == _arrayOfTypes[1])
            {
                sMsgErr = "Zugang nicht erlaubt.";
            }
            else if (sError == _arrayOfTypes[2])
            {
                sMsgErr = "Die Datei wurde nicht gefunden.";
            }
            else if (sError == _arrayOfTypes[3])
            {
                sMsgErr = "Ein E/A-Fehler ist auftritten.";
            }
            else if (sError == _arrayOfTypes[4])
            {
                sMsgErr = "Die Angegebene ID existiert nicht.";
            }
            else if (sError == _arrayOfTypes[5])
            {
                sMsgErr = "Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.";
                //errorMsg = "Ein nicht vorhandenes Objekt wird verweisen.";
            }
            else
            {
                sMsgErr = "Ein Fehler ist aufgetreten.";
            }

            return sMsgErr;
        }

The question is how do I retrieve the error message type so that I can check it against the array?

try
{
}
catch (Exception e)
{
   ErroHandler.GetErrorMsg(e.GetType());
}

Every object in .NET framework implements a GetType method which should give you the type.

Thanks I can now display the type of exception! I havent been able to find an exception that fits my type yet but Im sure it works
