Most Costly Method [C#]

[TheCPUWizard]

Consider the following:

public class SomeClass()
{
   protected virtual void SpecialWorkerMethod()
   {
       throw new Exception("Derived Class must Implement this Method");
   }
}

Can you see why the above just cause a client of mine SIGIFICANT money?

hint: The direct cause is directly related to C#, but the ROOT cause can happen in any language.

I'm guessing that this issue didn't show up until run time.

Restructuring the code using interfaces (and maybe constraints) probably would have allowed catching the problem during compile time.

1) Yup, right hile rinning for the client.

2) in C# abstract ould have been appropriate. In C++ making the method "pure" would have solved the problem at BUILD time.

I'm afraid I don't know, but I'd like to find out. What was the problem?

Simple. Somebody (no longer employeed by the client company because he also wrote the faulty base class) forgot to override a method in a derived class, that the base class was not setup to catch this at compile time.

It seems a bit rough to sack someone over this : after all testing should have shown this up.

We all make mistakes occasionally... don't we ?

If a mistake costs $3 million dollars (yes, actual amount), then SOMEONE is going to lose their job.

Well, it was probably justified, but with some 'background' which would qualify it. I'm glad it wasn't me... Isn't there still death for 'treason' for gov't workers?

No kidding ? How did it sum up to $3 million ?? I mean did they loose future sale or they lost agreement or something ?

If a mistake costs $3 million dollars...

A wise business man once took on a trainee that blew a huge deal costing $11M. The young many went to turn in his resignation and the older business man said, "Boy, I just spent $11M training you. I don't want you to go."

That's one mistake they'll NEVER make again!

My client had a delivery commitment. A missed milestone invoked a thirty day penality (they met with their client one per month). When the program was being demonstrated, and blew up, it was deemed "not ready for user acceptance", and the commitment was declared "not met".

What process changes do you plan to make to prevent this sort of thing from happening in the future?

[RaleTheBlade]

Yikes, I wouldn't wanna have had that guys job... I use C# all the time and I thought it was a hefty method simply because of the exception being thrown and bubbling up the call stack. Also, if it had to be implemented, why didn't he use an interface?

I work for a small company doing all their software, I love my job, but when software development starts to become like boot camp thats when I pack my bags, lol.

You'll never earn very much then... the toughest jobs I've had have also the highest paid.
