public protected:
virtual Expression^ VisitExtension(
	Expression^ node
)

Parameters

node
Type: System.Linq.Expressions::Expression^

The expression to visit.

Return Value

Type: System.Linq.Expressions::Expression^

The modified expression, if it or any subexpression was modified; otherwise, returns the original expression.

This can be overridden to visit or rewrite specific extension nodes.

If it is not overridden, this method will call VisitChildren, which gives the node a chance to walk its children. By default, VisitChildren will try to reduce the node.
