LINQ stands for Language Integrated Query. LINQ is a data querying methodology that provides querying capabilities to .NET languages with a syntax similar to a SQL query.
LINQ has a great power of querying on any source of data. The data source could be collections of objects, database or XML files. We can easily retrieve data from any object that implements the IEnumerable<T> interface.
Advantages of LINQ
- LINQ offers an object-based, language-integrated way to query over data no matter where that data came from. So through LINQ, we can query a database and XML as well as collections.
- Compile-time syntax checking.
It allows you to query collections like arrays, enumerable classes, etc... in the native language of your application, like in VB or C# in much the same way you would query a database using SQL.
