Expression.MakeBinary Method (ExpressionType, Expression, Expression, Boolean, MethodInfo, LambdaExpression)

Creates a BinaryExpression, given the left operand, right operand, implementing method and type conversion function, by calling the appropriate factory method.

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

public static BinaryExpression MakeBinary(
	ExpressionType binaryType,
	Expression left,
	Expression right,
	bool liftToNull,
	MethodInfo method,
	LambdaExpression conversion


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.
Type: System.Boolean
true to set IsLiftedToNull to true; false to set IsLiftedToNull to false.
Type: System.Reflection.MethodInfo
A MethodInfo that specifies the implementing method.
Type: System.Linq.Expressions.LambdaExpression
A LambdaExpression that represents a type conversion function. This parameter is used only if binaryType is Coalesce or compound assignment..

Return Value

Type: System.Linq.Expressions.BinaryExpression
The BinaryExpression that results from calling the appropriate factory method.


binaryType does not correspond to a binary expression node.


left or right is null.

The binaryType parameter determines which BinaryExpression factory method this method will call. For example, if binaryType is Subtract, this method invokes Subtract. The liftToNull, method and conversion parameters are ignored if the appropriate factory method does not have a corresponding parameter.
