.NET Forum / .NET Framework / New Users / January 2005build / design time errors?
Hi, Is there any way to control the raising of "build" errors? For example - is there any possible way of, for example, raising a build error if the object user tries to call method(x) before having set property y ? Thanks > Hi, > > Is there any way to control the raising of "build" errors?

How could the compiler determine what the runtime sequence of events would be? This is the sort of thing you have to do at runtime. John Saunders The compiler can detect code that cannot be reached, and throws warnings about that; how, particularly, is "require-x-before-y" really any different? Conceptually, these seem like very similar concepts, and I don't see why the compiler mechanisms that do dead-code detection could not be adapted for this purpose as well. Is it just that nobody has bothered to teach the compiler that particular trick, or is there something more subtle I'm not seeing? >> Hi, >> [quoted text clipped - 9 lines] > > John Saunders > The compiler can detect code that cannot be reached, and throws warnings > about that; how, particularly, is "require-x-before-y" really any [quoted text clipped - 5 lines] > the compiler that particular trick, or is there something more subtle I'm > not seeing? The compiler knows the code paths within a method and can determine that a piece of code might not be reached. But if you're talking about a publicly accessible property, the compiler has no way to determine what piece of code might ultimately set that property. It might be set by code which is not even in the same compilation. John Saunders Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
