BinaryExpression Class

Updated: November 2007

Represents an expression that has a binary operator.

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

Syntax

Visual Basic (Declaration)

Public NotInheritable Class BinaryExpression _
    Inherits Expression

Visual Basic (Usage)

Dim instance As BinaryExpression

public sealed class BinaryExpression : Expression

Visual C++

public ref class BinaryExpression sealed : public Expression

public final class BinaryExpression extends Expression

JScript

public final class BinaryExpression extends Expression

Remarks

The following tables summarize the factory methods that can be used to create a BinaryExpression that has a specific node type, represented by the NodeType property. Each table contains information for a specific class of operations such as arithmetic or bitwise.

Binary Arithmetic Operations

Node Type	Factory Method
Add	Add
AddChecked	AddChecked
Divide	Divide
Modulo	Modulo
Multiply	Multiply
MultiplyChecked	MultiplyChecked
Power	Power
Subtract	Subtract
SubtractChecked	SubtractChecked

Bitwise Operations

Node Type	Factory Method
And	And
Or	Or
ExclusiveOr	ExclusiveOr

Shift Operations

Node Type	Factory Method
LeftShift	LeftShift
RightShift	RightShift

Conditional Boolean Operations

Node Type	Factory Method
AndAlso	AndAlso
OrElse	OrElse

Comparison Operations

Node Type	Factory Method
Equal	Equal
NotEqual	NotEqual
GreaterThanOrEqual	GreaterThanOrEqual
GreaterThan	GreaterThan
LessThan	LessThan
LessThanOrEqual	LessThanOrEqual

Coalescing Operations

Node Type	Factory Method
Coalesce	Coalesce

Array Indexing Operations

Node Type	Factory Method
ArrayIndex	ArrayIndex

In addition, the MakeBinary methods can also be used to create a BinaryExpression. These factory methods can be used to create a BinaryExpression of any node type that represents a binary operation. The parameter of these methods that is of type NodeType specifies the desired node type.

Examples

The following example creates a BinaryExpression object that represents the subtraction of one number from another.

Visual Basic

' 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), _
        System.Linq.Expressions.Expression.Constant(14))

Console.WriteLine(binaryExpression.ToString())

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

// 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));

Console.WriteLine(binaryExpression.ToString());

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