The
architecture diagram explains the different types of LINQ which are used for
querying data from different sources of data. Also, we have seen some of the new
features of C# 3.0 and above in relation to LINQ. This chapter also explained some
of the new features introduced in C# 3.5 such as partial methods, expressions and
anonymous types with some examples for each of those. We will be looking into
details of LINQ features and its usability in the coming chapters.
LINQ to Objects
LINQ to Objects means that we can use LINQ to query objects in a collection. We can
access the in-memory data structures using LINQ. We can query any type of object
that implements the IEnumerable interface or IEnumerable
, which is of generic
type. Lists, arrays, and dictionaries are some collection objects that can be queried
using LINQ. If we don't use LINQ, we have to use the looping method to filter the
values in a collection. We have to go through the values one-by-one and then find the
required details. However, using LINQ we can directly query collections and filter
the required values without using any looping.
