Public Function FullOuterJoin (left As DbExpression, right As DbExpression, joinCondition As Func(Of DbExpression, DbExpression, DbExpression)) As DbJoinExpressionParameters
- left
- DbExpression
A DbExpression that specifies the left set argument.
- right
- DbExpression
A DbExpression that specifies the right set argument.
- joinCondition
- Func<DbExpression,DbExpression,DbExpression>
A method representing the condition on which to join. This method must produce an expression with a Boolean result type that provides the logic of the join condition.
Returns
A new DbJoinExpression, with an DbExpressionKind of FullOuterJoin, that represents the full outer join operation applied to the left and right input sets under the given join condition.
Exceptions
left, right or joinCondition is null.
-or-
The expression produced by joinCondition is null.
left or right does not have a collection result type.
-or-
The expression produced by joinCondition does not have a Boolean result type.
