Linq To Objects

LINQ to Objects

LINQ to Objects • LINQ to Objects allows .NET developers to write “queries” over collections of objects. • Traditionally, working with collections of objects meant writing a lot of looping code using for loops or foreach loops to iterate through a list carrying out filtering using if statements, and some action like keeping a running sum of a total property. • LINQ frees you from having to write looping code; it allows you to write queries that filter a list or calculate aggregate functions on elements in a collection as a set.

An example of calculating the aggregate sum of all the elements would look like

If you are used to Select-From-WhereOrderBy, it might take some time to overcome the muscle memory and move to From-Where-OrderBy-Select.
