Expression.VisitChildren Method (ExpressionVisitor)

.NET Framework (current version)
 

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.

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

protected internal virtual Expression VisitChildren(
	ExpressionVisitor visitor
)

Parameters

visitor
Type: System.Linq.Expressions.ExpressionVisitor

An instance of Func<T, TResult>.

Return Value

Type: System.Linq.Expressions.Expression

The expression being visited, or an expression which should replace it in the tree.

Override this method to provide logic to walk the node's children. A typical implementation will call visitor.Visit on each of its children, and if any of them change, should return a new copy of itself with the modified children.
