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)

static member MakeBinary : 
        binaryType:ExpressionType *
        left:Expression *
        right:Expression -> BinaryExpression


Type: System.Linq.Expressions.ExpressionType

The ExpressionType that specifies the type of binary operation.

Type: System.Linq.Expressions.Expression

An Expression that represents the left operand.

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.

Exception Condition

binaryType does not correspond to a binary expression node.


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.
