What is join in Linq?
Also asked, can we use left join in Linq?
A left outer join is a join in which each element of the first collection is returned, regardless of whether it has any correlated elements in the second collection. You can use LINQ to perform a left outer join by calling the DefaultIfEmpty method on the results of a group join.
Additionally, what is include in Linq? If you want to have the object tree, you need to use Include because of lazy loading. INCLUDE - Specifies the related objects to include in the query results.
Subsequently, one may also ask, is Linq join inner or outer?
One commonly used feature of Language-Integrated Query (LINQ) is the facility to combine two sequences of related data using joins. The standard join operation provides an inner join but with a minor modification can be changed to give a left outer join.
What is DefaultIfEmpty in Linq?
The DefaultIfEmpty operator is used to replace an empty collection or sequence with a default valued singleton collection or sequence. Or in other words, it returns a collection or sequence with default values if the source is empty, otherwise return the source.
