Assembly:  EntityFramework (in EntityFramework.dll)

NameDescription
System_CAPS_pubmethodSystem_CAPS_staticFullOuterJoin(DbExpression, DbExpression, Func<DbExpression, DbExpression, DbExpression>)

Creates a new DbJoinExpression that joins the sets specified by the left and right expressions, on the specified join condition, using FullOuterJoin as the DbExpressionKind.

System_CAPS_pubmethodSystem_CAPS_staticFullOuterJoin(DbExpressionBinding, DbExpressionBinding, DbExpression)

Creates a new DbJoinExpression that joins the sets specified by the left and right expression bindings, on the specified join condition, using FullOuterJoin as the DbExpressionKind.


DbExpressionBuilder.FullOuterJoin Method (DbExpression, DbExpression, Func<DbExpression, DbExpression, DbExpression>)

Creates a new DbJoinExpression that joins the sets specified by the left and right expressions, on the specified join condition, using FullOuterJoin as the DbExpressionKind.

public static DbJoinExpression FullOuterJoin(
	this DbExpression left,
	DbExpression right,
	Func<DbExpression, DbExpression, DbExpression> joinCondition
)

Parameters

left
Type: System.Data.Entity.Core.Common.CommandTrees.DbExpression

A DbExpression that specifies the left set argument.

right
Type: System.Data.Entity.Core.Common.CommandTrees.DbExpression

A DbExpression that specifies the right set argument.

joinCondition
Type: System.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.

Return Value

Type: System.Data.Entity.Core.Common.CommandTrees.DbJoinExpression

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.

Exception Condition
ArgumentNullException

left, right or joinCondition is null.

ArgumentException

left or right does not have a collection result type.

ArgumentNullException

The expression produced by joinCondition is null.

ArgumentException

The expression produced by joinCondition does not have a Boolean result type.
