Parameters
Type Name Description
System.Collections.ObjectModel.ReadOnlyCollection<ParameterExpressionSlim> variables

The Variables property of the result.
System.Collections.ObjectModel.ReadOnlyCollection<ExpressionSlim> expressions

The Expressions property of the result.
Returns
Type Description
BlockExpressionSlim

This expression if no children changed, or an expression with the updated children.
