MoreEnumerableRightJoinTSource, TKey, TResult Method (IEnumerableTSource, IEnumerableTSource, FuncTSource, TKey, FuncTSource, TResult, FuncTSource, TSource, TResult) |
Performs a right outer join on two homogeneous sequences.
Additional arguments specify key selection functions and result
projection functions.

Parameters
- first
- Type: System.Collections.GenericIEnumerableTSource
The first sequence of the join operation. - second
- Type: System.Collections.GenericIEnumerableTSource
The second sequence of the join operation. - keySelector
- Type: SystemFuncTSource, TKey
Function that projects the key given an element of one of the
sequences to join. - secondSelector
- Type: SystemFuncTSource, TResult
Function that projects the result given just an element from
second where there is no corresponding element
in first. - bothSelector
- Type: SystemFuncTSource, TSource, TResult
Function that projects the result given an element from
first and an element from second
that match on a common key.
Type Parameters
- TSource
-
The type of elements in the source sequence.
- TKey
-
The type of the key returned by the key selector function.
- TResult
-
The type of the result elements.
Return Value
Type:
IEnumerableTResultA sequence containing results projected from a right
outer join of the two input sequences.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
