Advantages of pushing XML in custom Exception Library!

Hi there,

I had been wondering for a while. I am building a very efficient Custom Exception Library. But i wasn't that sure whether i should be using XML or not.

There are 3 ways which i thought off.

1) The tradional way, how my office people handles exception in C language.

Exceptions are stored in enum

typedef enum
{
ERR_PORTDEAD = -50,
ERR_ONHOLD,
OK = 0
} STATUSERROR;

They do validations by;

if (CheckStatusPort(portNumber))
return ERR_PORTDEAD;

once detect to the client side, you had to manually concanenate the error message with a description. Troublesome.

I don't like this way.

2) So yesterday, i think of pushing my exceptions messages and stored into hashtable.

Example,

Key = -50
Value = "Error Port Dead"

Hashtable table = new Hasthtable();
table.Add(-50, "Error Port Dead");

Just keep on adding.

Once i want to do this;

If (CheckStatusReport(portNumber))
throw new CustomeException(table[-50]);

So at the end it throws out everything.

3) But the problem, is all the codes need to be manually written in C#.

Is there a way? XML or Text File. Whatever.

<xml>
<Error>
<Type>Port</Type>
<ID>-50</ID>
<Desc>Port is dead</Desc>
<Solution>Additional - cool!</Solution>
</Error>
</xml>

Somehow you will load this inside the class library,

throw new Exception((get_from_the_xml_file_with_key_-50));

What do you think?

At least in future, they can change the xml file without recompiling.

At the end of the day, i need to achieve a better, efficient of way of error handling.

Of course i am building a custom exception class that inherits from System.ApplicationException.

Can anyone shed their personal comments please based on their experiences?

Thanks.
