, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more veri than is actually needed, and we waste cycles doing the filtering in the client.
are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object birli a runtime-traversable abstract syntax tree that kişi be understood by the given query provider (for the most part, you can't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

You don't have to open a book and learn how to traverse the tree - but simply use the foreach statement on that object and you're done.)
The major difference between IQueryable and C# IEnumerable Nedir IEnumerable is that IQueryable executes query with filters whereas IEnumerable executes the query first and then it filters the veri based on conditions.
There are pros and cons to both. If you call ToList, you may remove some mystery as to when the query gets executed. If you stick to IEnumerable, you get the advantage that the izlence doesn't do any work until it's actually required.
