No Lamba syntax shown if .ToList() is used

sgmoore · November 2012

A query like

(from r in Customers where r.City == "London" select r).Dump();

show the lamba syntax of

Customers
   .Where (r => (r.City == "London"))

but nothing is shown for the following query

(from r in Customers where r.City == "London" select r).ToList().Dump();

It's not causing me a problem, but was just wondering why?

In order to display the lambda syntax, LINQPad's Dump method needs to introspect the expression tree. This is not possible after you call ToList because that information is lost at that point - all you have is a list of objects.
