This article mainly introduces "what is the LINQ architecture". In the daily operation, I believe many people have doubts about the LINQ architecture. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what is the LINQ architecture?" Next, please follow the editor to study!

LINQ, short for Language Integrated Query, is a feature integrated into the .NET programming language. It has become an integral part of the programming language, and it can get the benefits of strong typed languages such as compile-time syntax checking, rich metadata, intelligent awareness, static typing and so on. And it also makes it easy to query the information in memory, not just the external data source.

LINQ defines a set of standard query operators to more directly declare a uniform way of spanning, filtering, and projecting operations in all .NET-based programming languages, standard query operators allow queries to act on all sources based on IEnumerable interfaces, and it also allows third-party domain-specific operators appropriate to the target domain or technology to expand the set of standard query operators and, more importantly, Third-party operators are free to replace standard query operators with their own implementations that provide additional services, and according to the custom of the LINQ pattern, these queries prefer the same language integration and tool support as standard query operators.

Let's take a look at the LINQ architecture in general

Under .NET 3.5, Microsoft provided us with some namespaces.

LINQ consists of five parts: LINQ to Objects, LINQ to DataSets, LINQ to SQL, LINQ to Entities and LINQ to XML.

LINQ to SQL is a. Net language integrated query based on relational data, which is used to manage relational data in the form of objects and provides rich query functions. It is based on the integration of SQL-based schema definitions in the common language type system, which provides strong typing on top of relational data while maintaining the expressiveness of the relational model and the performance of direct query evaluation of the underlying storage.

LINQ to XML implements operations on XML under the System.Xml.LINQ namespace. Use efficient, easy-to-use, in-memory XML tools to provide XPath/XQuery functions in the host programming language. The LINQ architecture is described above.

At this point, the study of "what is the architecture of LINQ" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
