Inherit from a generic base class, apply a constraint, and implement an interface in C#
...r locating, downloading, and searching through a highly technical 503 page Word document buried off a link in MSDN. Thats pretty rough. This was the most efficient use of my time and has the added benefit that it may help someone else later. The link to the C# Lang Spec for those interested is: msdn...
Do I really have a car in my garage? [duplicate]
...ll check that you only perform operation allowed on any Vehicle. (In other words, methods and attributes visible in the Vehicle declaration).
You can explain to the compiler that "you in fact know this Vehicle is a Car", by using an explicit cast (Car). the compiler will believe you -- even if in J...
What's the false operator in C# good for?
...nd T.&(x, y) is an invocation of the selected operator &. In other words, x is first evaluated and operator false is invoked on the result to determine if x is definitely false. Then, if x is definitely false, the result of the operation is the value previously computed for x. Otherwise, y i...

Correct format specifier to print pointer or address?
...thing else pointer' address for the same memory location. This would be a word-addressed, instead of byte-addressed, machine. Such machines are not common (probably not available) these days, but the first machine I worked on after university was one such (ICL Perq).
