NET 4. It contains useful and in-depth information on all the conceptual foundations of C ; and at the same time, teaches you how to implement each language concept programmatically, by providing most appropriate examples with full explanations. This unique book on C provides more coverage of C than any other book; no doubt, every aspect of the book is worth its price. Table of Contents Part I: Introducing ASP. NET Entity Framework.

Malik Maliki. It performs an ordinal comparison of the strings, which is basically a byte-by-byte comparison. In many cases this is exactly the type of comparison you want, especially when comparing strings whose values are set programmatically, such as file names, environment variables, attributes, etc.

Using the Equals method signature that includes a comparisonType every time you compare strings, though, will not only make your code clearer, it will make you explicitly think about which type of comparison you need to make. This is a worthwhile thing to do, because even if English may not provide a whole lot of differences between ordinal and culture-sensitive comparisons, other languages provide plenty, and ignoring the possibility of other languages is opening yourself up to a lot of potential for errors down the road.

WriteLine s. Ordinal ; Console. CurrentCulture ; Console. Here are some basic guidelines: When comparing strings that were input by the user, or are to be displayed to the user, use a culture-sensitive comparison CurrentCulture or CurrentCultureIgnoreCase.

When comparing programmatic strings, use ordinal comparison Ordinal or OrdinalIgnoreCase.

InvariantCulture and InvariantCultureIgnoreCase are generally not to be used except in very limited circumstances, because ordinal comparisons are more efficient. If a culture-aware comparison is necessary, it should usually be performed against the current culture or another specific culture.

In addition to the Equals method, strings also provide the Compare method, which gives you information about the relative order of strings instead of just a test for equality. Related: 12 Essential. Many still think, though, that because of the similarity between LINQ keywords and SQL statements, its only use is in code that queries databases.

While database querying is a very prevalent use of LINQ statements, they actually work over any enumerable collection i. Sum ; While this is a pretty simple example of how to avoid this common C programming problem, there are cases where a single LINQ statement can easily replace dozens of statements in an iterative loop or nested loops in your code.

And less code general means less opportunities for bugs to be introduced. Keep in mind, however, there may be a trade-off in terms of performance. In performance-critical scenarios, especially where your iterative code is able to make assumptions about your collection that LINQ cannot, be sure to do a performance comparison between the two methods.

But the error here is assuming we live in a perfect world. In fact, identical LINQ statements can return different results when executed on the exact same data, if that data happens to be in a different format.

Well, if myAccounts was a DbSet object that was set up with the default case-insensitive configuration , the where expression would still match that element.

However, if myAccounts was in an in-memory array, it would not match, and would therefore yield a different result for total. But wait a minute. Operators then follow T-SQL programming rules, not C programming rules, so the comparison in the above case ends up being case insensitive.

In general, even though LINQ is a helpful and consistent way to query collections of objects, in reality you still need to know whether or not your statement will be translated to something other than C under the hood to ensure that the behavior of your code will be as expected at runtime. C is strongly typed, so if the reference to the Sum method was invalid, the C compiler would certainly flag it as an error. We therefore know that it must exist, but where?

Moreover, where are the definitions of all the other methods that LINQ provides for querying or aggregating these collections? The answer is that Sum is not a method defined on the IEnumerable interface. Enumerable class: namespace System. The distinguishing characteristic of an extension method is the this modifier on its first parameter. Books | .NET

This similarity is just an arbitrary stylistic choice. Extension methods are brought into scope by including a using [namespace]; statement at the top of the file. If it finds one, it will pass the instance reference as the first argument to that extension method, then the rest of the arguments, if any, will be passed as subsequent arguments to the extension method.

Otherwise, it can be a bit confusing, especially at first. This is especially true when looking at code samples online, or at any other pre-written code. Even developers who are familiar with extension methods still get caught occasionally, when there is a method with the same name on the object, but its method signature differs in a subtle way from that of the extension method.
