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

Syntax

'Declaration
Protected Friend Overridable Function VisitExtension ( _
    node As Expression _

protected internal virtual Expression VisitExtension(
    Expression node
)

Parameters

Return Value

Type: System.Linq.Expressions.Expression
The modified expression, if it or any subexpression was modified; otherwise, returns the original expression.

Remarks

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.
