c# - Similar to Extension Methods Functionality - Can we extend properties -

c# - Disposing my System.IDisposable object in my finalizer -

-
there several discussions here on stackoverflow if object manages other managed objects implement system.idisposable . note: below not talking unmanaged code. understand importance of cleaning unmanaged code most of discussions if object owns managed object implements system.idisposable , should implement system.idisposable , in case should call dispose() of disposable objects object holds. logical, because don't know whether disposable object own uses unmanaged code. know creator of other object thought wise if you'd call dispose don't need object anymore. a explanation of disposable pattern given here on stackoverflow, edited community wiki: proper use of idisposable interface quite often, , in mentioned link read: "you don't know order in 2 objects destroyed. entirely possible in dispose() code, managed object you're trying rid of no longer there." this baffles me, because thought long object holds reference object x, object x

c# - Does base class gets instantiated for every new instance? -

-
i have been thinking how clr creates new instances. consider code: public class base { public base() { } } public class derived : base { public derived() : base() { } } these questions: does system.object instance created every time line of code, var baseobj = new base(); ? how many instances there in memory? 2 or 1? for line of code: var derobj = new derived(); . how many instances created? 3 or 2? in both samples, there 1 object. there 1 piece of memory allocated , base class 'merges' parents. there 1 class containing methods, fields , properties derived base classes, including base-class-of-all. object . what think happen if var derivedobj = new derived(); creates 2 instances? how refer 1 not assigned baseobj ? there no use in keeping 2 instances of classes alive. 1 do.
