C# has replaced considerably because it was once first brought. With the numerous upgraded good points, C# is extra expressive than ever. even if, a close realizing is needed to get the main out of the language.

C# intensive, moment Edition is a completely revised, up to date publication that covers the hot positive aspects of C# four in addition to Code Contracts. In it, you’ll see the subtleties of C# programming in motion, studying how you can paintings with high-value positive factors that you’ll be comfortable to have on your toolkit. The publication is helping readers steer clear of hidden pitfalls of C# programming via figuring out “behind the scenes” issues.

Sample text

3 Framework libraries Libraries provide code that’s available to our programs. NET are largely built as IL themselves, with native code used only where necessary. This is a mark of the strength of the runtime: your own code isn’t expected to be a second-class citizen—it can provide the same kind of power and performance as the libraries it utilizes. The amount of code in the library is much greater than that of the runtime, in the same way that there’s much more to a car than the engine. The framework libraries are partially standardized.

WriteLine(product); } } Okay, this is not difficult code to understand. WriteLine. The dependency is obvious because of the nesting. The following listing demonstrates how C# 2 lets us flatten things out a bit. ForEach(print); The test variable is initialized using the anonymous method feature we saw in the previous section; the print variable initialization uses another new C# 2 feature called method group conversions that makes it easier to create delegates from existing methods. 2 C# 4 does provide one feature that can be relevant when sorting, called generic variance, but giving an example here would require too much explanation.

Price = price; } You always have to specify a constant value when you declare an optional parameter. It doesn’t have to be null; that just happens to be the default we want in this situation. This is applicable to any type of parameter, although for reference types other than strings you are limited to null as the only constant value available. 4 summarizes the evolution we’ve seen across different versions of C#. So far the features have been useful, but perhaps nothing to write home about. Next we’ll look at something rather more exciting: LINQ.
