BinaryExpression Class

Represents an expression that has a binary operator.

System.Object
  System.Linq.Expressions.Expression
    System.Linq.Expressions.BinaryExpression

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

public class BinaryExpression : Expression

The BinaryExpression type exposes the following members.

  NameDescription
Public propertySupported by Portable Class LibraryCanReduceGets a value that indicates whether the expression tree node can be reduced. (Overrides Expression.CanReduce.)
Public propertySupported by Portable Class LibraryConversionGets the type conversion function that is used by a coalescing or compound assignment operation.
Public propertySupported by Portable Class LibraryIsLiftedGets a value that indicates whether the expression tree node represents a lifted call to an operator.
Public propertySupported by Portable Class LibraryIsLiftedToNullGets a value that indicates whether the expression tree node represents a lifted call to an operator whose return type is lifted to a nullable type.
Public propertySupported by Portable Class LibraryLeftGets the left operand of the binary operation.
Public propertySupported by Portable Class LibraryMethodGets the implementing method for the binary operation.
Public propertySupported by Portable Class LibraryNodeTypeGets the node type of this Expression. (Inherited from Expression.)
Public propertySupported by Portable Class LibraryRightGets the right operand of the binary operation.
Public propertySupported by Portable Class LibraryTypeGets the static type of the expression that this Expression represents. (Inherited from Expression.)

  NameDescription
Protected methodSupported by Portable Class LibraryAcceptDispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall. (Overrides Expression.Accept(ExpressionVisitor).)
Public methodSupported by Portable Class LibraryEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodSupported by Portable Class LibraryFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Portable Class LibraryGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodSupported by Portable Class LibraryGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by Portable Class LibraryMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Portable Class LibraryReduceReduces the binary expression node to a simpler expression. (Overrides Expression.Reduce().)
Public methodSupported by Portable Class LibraryReduceAndCheckReduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced. (Inherited from Expression.)
Public methodSupported by Portable Class LibraryReduceExtensionsReduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type. (Inherited from Expression.)
Public methodSupported by Portable Class LibraryToStringReturns a textual representation of the Expression. (Inherited from Expression.)
Public methodSupported by Portable Class LibraryUpdateCreates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Protected methodSupported by Portable Class LibraryVisitChildrenReduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible. (Inherited from Expression.)

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.

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.

The following example creates a BinaryExpression object 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));

Console.WriteLine(binaryExpression.ToString());

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