Edit Question
Title
Body
An article in MSDN Magazine discusses the notion of Read Introduction and gives a code sample which can be broken by it. public class ReadIntro { private Object _obj = new Object(); void PrintObj() { Object obj = _obj; if (obj != null) { Console.WriteLine(obj.ToString()); // May throw a NullReferenceException } } void Uninitialize() { _obj = null; } } Notice this "May throw a NullReferenceException" comment - I never knew this was possible. So my question is: how can I protect against read introduction? I would also be really grateful for an explanation exactly when the compiler decides to introduce reads, because the article doesn't include it.
