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 static BinaryExpression MakeBinary(
	ExpressionType binaryType,
	Expression left,
	Expression right
)

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.

Return Value

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

ExceptionCondition
ArgumentException

binaryType does not correspond to a binary expression node.

ArgumentNullException

left or right is null.

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.
System.Linq.Expressions.BinaryExpression binaryExpression =
    System.Linq.Expressions.Expression.MakeBinary(
        System.Linq.Expressions.ExpressionType.Subtract,
        System.Linq.Expressions.Expression.Constant(53),
        System.Linq.Expressions.Expression.Constant(14));

outputBlock.Text += binaryExpression.ToString() + "\n";

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