Examples

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)

' 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)

Properties

CanReduce	Gets a value that indicates whether the expression tree node can be reduced.
CanReduce	Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form. (Inherited from Expression)
Conversion	Gets the type conversion function that is used by a coalescing or compound assignment operation.
IsLifted	Gets a value that indicates whether the expression tree node represents a lifted call to an operator.
IsLiftedToNull	Gets 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.
Left	Gets the left operand of the binary operation.
Method	Gets the implementing method for the binary operation.
NodeType	Gets the node type of this Expression. (Inherited from Expression)
Right	Gets the right operand of the binary operation.
Type	Gets the static type of the expression that this Expression represents. (Inherited from Expression)

Methods

Accept(ExpressionVisitor)	Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression).
Accept(ExpressionVisitor)	Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression). (Inherited from Expression)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Reduce()	Reduces the binary expression node to a simpler expression.
Reduce()	Reduces 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)
ReduceAndCheck()	Reduces 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)
ReduceExtensions()	Reduces 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)
ToString()	Returns a textual representation of the Expression. (Inherited from Expression)
Update(Expression, LambdaExpression, Expression)	Creates 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.
VisitChildren(ExpressionVisitor)	Reduces 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)
