LINQ Part 4 – Standard Query Operators

LINQ Part 4 – Standard Query Operators

At compile time query expressions are converted into Standard Query Operator method calls. Query expressions can be compiled to expression trees or to delegates, depending on the type that the query is applied to. IEnumerable(Of T) queries are compiled to delegates. IQueryable and IQueryable(Of T) queries are compiled to expression trees.

This section gives an overview on standard query operators.

Standard query operators are methods operate on sequence which implements either IQueryable or IEnumerable interface and help to achieve provide LINQ pattern. These methods are provided as extension methods to these interfaces. We can also replace the standard query operators with our own implementations using method extension feature.
