Expression.MakeBinary Method (ExpressionType, Expression, Expression)

Creates a BinaryExpression, given the left and right operands, by calling an appropriate factory method.

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

Public Shared Function MakeBinary ( _
	binaryType As ExpressionType, _
	left As Expression, _
	right As Expression _
) As BinaryExpression


Type: System.Linq.Expressions.ExpressionType
The ExpressionType that specifies the type of binary operation.
Type: System.Linq.Expressions.Expression
An Expression that represents the left operand.
Type: System.Linq.Expressions.Expression
An Expression that represents the right operand.

Return Value

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


binaryType does not correspond to a binary expression node.


left or right is Nothing.

The binaryType parameter determines which BinaryExpression factory method this method calls. For example, if binaryType is Subtract, this method invokes Subtract.

The following example demonstrates how to use the MakeBinary(ExpressionType, Expression, Expression) method to create a BinaryExpression that represents the subtraction of one number from another.

' Create a BinaryExpression that represents subtracting 14 from 53.
Dim binaryExpression As System.Linq.Expressions.BinaryExpression = _
    System.Linq.Expressions.Expression.MakeBinary( _
        System.Linq.Expressions.ExpressionType.Subtract, _
        System.Linq.Expressions.Expression.Constant(53), _

outputBlock.Text &= binaryExpression.ToString() & vbCrLf

' This code produces the following output:
' (53 - 14)
