POIs there any reason to not use my IoC as a general Settings Repository?
text
Body
copied!<p>Suppose that the <strong>ApplicationSettings</strong> class is a general repository of settings that apply to my application such as TimeoutPeriod, DefaultUnitOfMeasure, HistoryWindowSize, etc... And let's say MyClass makes use of one of those settings - DefaultUnitOfMeasure.</p> <p>My reading of proper use of Inversion of Control Containers - and please correct me if I'm wrong on this - is that you define the dependencies of a class in its constructor:</p> <pre><code>public class MyClass { public MyClass(IDataSource ds, UnitOfMeasure default_uom) {...} } </code></pre> <p>and then call instantiate your class with something like</p> <pre><code>var mc = IoC.Container.Resolve<MyClass>(); </code></pre> <p>Where <strong>IDataSource</strong> has been assigned a concrete implementation and default_uom has been wired up to instantiate from the <strong>ApplicationSettings.DefaultUnitOfMeasure</strong> property. I've got to wonder however, if all these hoops are really that necessary to jump through. What trouble am I setting myself up for should I do</p> <pre><code>public class MyClass { public MyClass(IDataSource ds) { UnitOfMeasure duom = IoC.Container.Resolve<UnitOfMeasure>("default_uom"); } } </code></pre> <p>Yes, many of my classes end up with a dependency on <strong>IoC.Container</strong> but that is a dependency that most of my classes will have anyways. It seems like I maybe should make full use of it as long as the classes are coupled. Please Agile gurus, tell me where I'm wrong.</p>
