This is shown in the
following code:
public static IEnumerable
JoinTKey, TResult>
(
IEnumerable outer,
Enumerable inner,
Func outerKeySelector,
Func innerKeySelector,
Func resultSelector,
IEqualityComparer comparer
)
public static IQueryable Join
(
IQueryable outer,
IEnumerable inner,
Expression> outerKeySelector,
Expression> innerKeySelector,
Expression> resultSelector,
IEqualityComparer comparer
)
This is similar to inner join in relation database terms. These operators join
two different sequences and collect common information from the sequences
with the help of matching keys in the sequences. The outerKeySelector and
innerKeySelector arguments specify functions that extract the join key values
from elements of the outer and inner sequences, respectively.
