LINQ (Language Integrated Query) is an expression language used to retrieve data from data source. This data source can be a SQL data provider or XML file. LINQ is mainly developed to overcome an extra overhead of learning so many query languages. There are lot of query languages available as of now and they are changing day by day. Developers have to learn each of them based on application needs.
LINQ plays a vital role in this. It is a generalized query language which can be used with various kinds of data sources and formats.
Here is a simple program which demonstrates LINQ functioning.
The query doesn't work by specifying the query variable itself. "foreach" loop refers to the query variable and then the logic written in query is executed. Then developer can process on fetched data in the loop. Hers is how the LINQ works.
