Definition

Namespace:
System.Data.Common.CommandTrees.ExpressionBuilder
Assembly:
System.Data.Entity.dll

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

Overloads

InnerJoin(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 InnerJoin as the DbExpressionKind.
InnerJoin(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 InnerJoin as the DbExpressionKind.

InnerJoin(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 InnerJoin as the DbExpressionKind.

<Extension()>
Public Function InnerJoin (left As DbExpression, right As DbExpression, joinCondition As Func(Of DbExpression, DbExpression, DbExpression)) As DbJoinExpression

Parameters

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

DbJoinExpression

A new DbJoinExpression, with an DbExpressionKind of InnerJoin, that represents the inner join operation applied to the left and right input sets under the given join condition.

Exceptions

ArgumentNullException

left, right or joinCondition is null.

-or-

The expression produced by joinCondition is null.

ArgumentException

left or right does not have a collection result type.

-or-

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

Applies to

InnerJoin(DbExpressionBinding, DbExpressionBinding, DbExpression)
