A preview of LINQ, code name for a set of extensions to the .NET Framework that encompass language-integrated data query, set, and transform operations. Remarks. Most of the LINQ to XML extension methods are axis methods that are used in LINQ queries. The methods in this class operate on collections and return collections. These methods enumerate the source collection, call the appropriate axis method on each item in the collection, and concatenate the results.he two Remove extension methods are not axis methods, however. These methods remove attributes or nodes from the XML tree. Note that there is another category of axis methods, implemented in the XElement, XDocument, and XNode classes. These extension method implementations live under the new System.Linq namespace, and define standard query operator extension methods that can be used by any .NET developer to easily query XML, Relational Databases, .NET objects that implement IEnumerable, and/or any other type of data structure. Hi Sahil, Extension Methods are actually implemented entirely by the compiler-no new IL instructions within the CLR are required to support them. 2  This means that you can use the VS Orcas C# compiler and write code that uses Extension Methods, and use the multi-targetting features to run it on a vanilla .NET 2.0 box. Extension methods enable you to add methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type.For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type.or a class library that you implemented, you shouldn't use extension methods to avoid incrementing the version number of an assembly. If you want to add significant functionality to a library for which you own the source code, you should follow the standard .NET Framework guidelines for assembly versioning. Language Integrated Query (LINQ, pronounced link) is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages, although ports exist for Java, PHP, JavaScript and ActionScript.hile LINQ is primarily implemented as a library for .NET Framework 3.5, it also defines optional language extensions that make queries a first-class language construct and provide syntactic sugar for writing queries. These extensions incude LINQ support for the C++/CLI language and simplified syntax or writing common types of database queries.CLinq project is a library that makes it possible to use LINQ technologies from the C++/CLI language.INQ includes extensions for the C# and VB.NET, but there are no plans for supporting LINQ in C++/CLI. Interactive Extensions. 1  Ix.NET : (included in this repository) The Interactive Extensions (Ix) is a .NET library which extends LINQ to Objects to provide many of the operators available in Rx but targeted for IEnumerable.2  IxJS: An implementation of LINQ to Objects and the Interactive Extensions (Ix) in JavaScript. RxPy: The Reactive Extensions for Python 3 (Rx.Py) is a set of libraries to compose asynchronous and event-based programs using observable collections and LINQ-style query operators in Python 3. The LINQ extension library is a collection of extensions written in C# that help in common programming tasks related to arrays, collections and any other type of enumerable. The library is organized in the following sections: Other Operators: Extensive unit testing is included for all functionality. library of LINQ extensions for statistical analysis, sequence generation and manipulation, pattern detection, pivot transformation and more. 1 Ix.NET : (included in this repository) The Interactive Extensions (Ix) is a .NET library which extends LINQ to Objects to provide many of the operators available in Rx but targeted for IEnumerable.

I can then use the same LINQ Where() extension method I used previously with objects and XML to retrieve a sequence of strongly-typed Person objects from the database whose first name starts with the letter S: Note how the query syntax is the same as with objects and XML.
