Expression.MakeBinary Method (ExpressionType, Expression, Expression, Boolean, MethodInfo)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Creates a BinaryExpression, given the left operand, right operand and implementing method, by calling the appropriate factory method.

Namespace: System.Linq.Expressions
Assembly: System.Core (in System.Core.dll)

Syntax

'Declaration
Public Shared Function MakeBinary ( _
    binaryType As ExpressionType, _
    left As Expression, _
    right As Expression, _
    liftToNull As Boolean, _
    method As MethodInfo _
) As BinaryExpression

public static BinaryExpression MakeBinary(
    ExpressionType binaryType,
    Expression left,
    Expression right,
    bool liftToNull,
    MethodInfo method
)

Parameters

binaryType
Type: System.Linq.Expressions.ExpressionType
The ExpressionType that specifies the type of binary operation.

left
Type: System.Linq.Expressions.Expression
An Expression that represents the left operand.

right
Type: System.Linq.Expressions.Expression
An Expression that represents the right operand.

liftToNull
Type: System.Boolean
true to set IsLiftedToNull to true; false to set IsLiftedToNull to false.

method
Type: System.Reflection.MethodInfo
A MethodInfo that specifies the implementing method.

Return Value

Type: System.Linq.Expressions.BinaryExpression
The BinaryExpression that results from calling the appropriate factory method.

Exceptions

Exception	Condition
ArgumentException	binaryType does not correspond to a binary expression node.
ArgumentNullException	left or right is nulla null reference (Nothing in Visual Basic).

Remarks

The binaryType parameter determines which BinaryExpression factory method this method will call. For example, if binaryType is Subtract, this method invokes Subtract. The liftToNull and method parameters are ignored if the appropriate factory method does not have a corresponding parameter.
