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)
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.

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.
Properties
CanReduce CanReduce CanReduce CanReduce 
Gets a value that indicates whether the expression tree node can be reduced. 
Conversion Conversion Conversion Conversion 
Gets the type conversion function that is used by a coalescing or compound assignment operation. 
IsLifted IsLifted IsLifted IsLifted 
Gets a value that indicates whether the expression tree node represents a lifted call to an operator. 
IsLiftedToNull IsLiftedToNull IsLiftedToNull 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 Left Left Left 
Gets the left operand of the binary operation. 
Method Method Method Method 
Gets the implementing method for the binary operation. 
NodeType NodeType NodeType NodeType 
Gets the node type of this Expression. (Inherited from Expression) 
Right Right Right Right 
Gets the right operand of the binary operation. 
Type Type Type Type 
Gets the static type of the expression that this Expression represents. (Inherited from Expression) 
Methods
Accept(ExpressionVisitor) Accept(ExpressionVisitor) Accept(ExpressionVisitor) Accept(ExpressionVisitor) 
Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression). 
Equals(Object) Equals(Object) Equals(Object) Equals(Object) 
Determines whether the specified object is equal to the current object. (Inherited from Object) 
GetHashCode() GetHashCode() GetHashCode() GetHashCode() 
Serves as the default hash function. (Inherited from Object) 
GetType() GetType() GetType() GetType() 
Gets the Type of the current instance. (Inherited from Object) 
MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone() 
Creates a shallow copy of the current Object. (Inherited from Object) 
Reduce() Reduce() Reduce() Reduce() 
Reduces the binary expression node to a simpler expression. 
ReduceAndCheck() ReduceAndCheck() ReduceAndCheck() 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() ReduceExtensions() ReduceExtensions() 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() ToString() ToString() ToString() 
Returns a textual representation of the Expression. (Inherited from Expression) 
Update(Expression, LambdaExpression, Expression) Update(Expression, LambdaExpression, Expression) Update(Expression, LambdaExpression, 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) VisitChildren(ExpressionVisitor) VisitChildren(ExpressionVisitor) 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)
