At this point, you have been introduced to the process of building query expressions using various C# query operators (such as from, in, where, orderby, and select). Also, you discovered that some functionality of the LINQ to Objects API can only be accessed when calling extension methods of the Enumerable class. The truth of the matter, however, is that when compiled, the C# compiler actually translates all C# LINQ operators into calls on methods of the Enumerable class. In fact, if you were really a glutton for punishment, you could build all of your LINQ statements using nothing but the underlying object model. A great many of the methods of Enumerable have been prototyped to take delegates as arguments. In particular, many methods require a generic delegate named Func<> defined within the System namespace of System.Core.dll. For example, consider the Where() method of Enumerable which is called on your behalf when you use the C# where LINQ query operator: // Overloaded versions of the Enumerable.Where<T>() method. // Note the second parameter is of type System.Func<>. public static IEnumerable<TSource> Where<TSource>(this IEnumerable<TSource> source, System.Func<TSource,int,bool> predicate) public static IEnumerable<TSource> Where<TSource>(this IEnumerable<TSource> source, System.Func<TSource,bool> predicate)

The Func<> delegate (as the name implies) represents a pattern for a given function with a set of arguments and a return value. If you were to examine this type using the Visual Studio 2010 object browser, you ll notice that the Func<> delegate can take between zero and four input arguments (here typed T1, T2, T3, and T4 and named arg1, arg2, arg3, and arg4), and a return type denoted by TResult: // The various formats of the Func<> delegate. public delegate TResult Func<T1,T2,T3,T4,TResult>(T1 arg1, T2 arg2, T3 arg3, T4 arg4) public delegate TResult Func<T1,T2,T3,TResult>(T1 arg1, T2 arg2, T3 arg3) public delegate TResult Func<T1,T2,TResult>(T1 arg1, T2 arg2) public delegate TResult Func<T1,TResult>(T1 arg1) public delegate TResult Func<TResult>() Given that many members of System.Linq.Enumerable demand a delegate as input, when invoking them, you can either manually create a new delegate type and author the necessary target methods, make use of a C# anonymous method, or define a proper lambda expression. Regardless of which approach you take, the end result is identical. While it is true that making use of C# LINQ query operators is far and away the simplest way to build a LINQ query expression, let s walk through each of these possible approaches just so you can see the connection between the C# query operators and the underlying Enumerable type.

For example, to check for a directory and cd into it if it exists, use this: test -d "$directory" && cd "$directory" To change directory and exit with an error if cd fails, use this: cd "$HOME/bin" || exit 1 The next command tries to create a directory and cd to it. If either mkdir or cd fails, it exits with an error: mkdir "$HOME/bin" && cd "$HOME/bin" || exit 1 Conditional operators are often used with if. In this example, the echo command is executed if both tests are successful: if [ -d "$dir" ] && cd "$dir" then echo "$PWD" fi

Building Query Expressions with Query Operators (Revisited)

To begin, create a new Console Application named LinqUsingEnumerable. The Program class will define a series of static helper methods (each of which is called within the Main() method) to illustrate the various manners in which you can build LINQ query expressions. The first method, QueryStringsWithOperators(), offers the most straightforward way to build a query expression and is identical to the code seen in the LinqOverArray example found earlier in this chapter: static void QueryStringWithOperators() { Console.WriteLine("***** Using Query Operators *****"); string[] currentVideoGames = {"Morrowind", "Uncharted 2", "Fallout 3", "Daxter", "System Shock 2"}; var subset = from game in currentVideoGames where game.Contains(" ") orderby game select game; foreach (string s in subset) Console.WriteLine("Item: {0}", s); } The obvious benefit of using C# query operators to build query expressions is the fact that the Func<> delegates and calls on the Enumerable type are out of sight and out of mind, as it is the job of the C# compiler to perform this translation. To be sure, building LINQ expressions using various query operators (from, in, where, or orderby) is the most common and straightforward approach.

Assertions are functions that verify whether certain conditions are true for example, that a field on the current page holds a specific value. You can think of assertions as the validation that the actions performed by the foregoing functions delivered the results that you expected. Each assertion either passes or fails based on whether what you are examining is true or false. Table 25-2 defines the assertion functions that you can use to verify your test results. Table 25-2.
