DbBinaryExpression.Left Property

Gets or sets the DbExpression that defines the left argument.

Namespace:  System.Data.Common.CommandTrees
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public DbExpression Left { get; }

Property Value

Type: System.Data.Common.CommandTrees.DbExpression
The DbExpression that defines the left argument.

ExceptionCondition
ArgumentNullException

The expression is null.

ArgumentException

The expression is not associated with the command tree of the DbBinaryExpression,

or its result type is not equal or promotable to the required type for the left argument.

Derived expression types might perform stricter type checks when the Left property is set. For example, DbUnionAllExpression requires that its left expression has a collection result type, while DbAndExpression requires a Boolean result type. Typically, derived expression types will not allow Left to be set to an expression with a result type that is not equal or promotable to the result type of the current value.
