c#in_dept原版,比较深入的讨论。This is a book about C#2 and 3—it’s as simple as that. I barely cover C#1, and only cover
the .NET Framework libraries and Common Language Runtime (CLR) when they’re
related to the language. This is a deliberate decision, and the result is quite a different
book from most of the C# and .NET books I’ve seen.
