Some collections are such that efficient search algorithms work on them
such as binary search if the collection is a type which is sorted.
I'm wondering how LINQ searches these collections and if it takes
advantage of the fact that some collections are sorted?
We were speculating that the standard .net 2.0 collections might
implement the IQueryable interface for those collections where there
are more efficient search algorithms.

In Linq, you can apparently get a meaningful body from and
expression's .ToString(); random question - does anybody know if linq
also includes a parser? It just seemed it might be a handy way to
write a safe but easy implementation (i.e. no codedom) for an
IBindingListView.Filter (by compiling to a Predicate<T>).
Anybody know if this is possible at all?

In my (Windows Forms) project I am using strongly typed datatables. Now I am
trying to convert my 'rowfilter/group by' query logic to Linq. Most queries I
can easily convert, but some I am having difficulties with: the ones dynamic
in nature. I solved it (temporary) by copy-pasting static queries. This is
not an ideal solution because now my code contains some duplicate code.
Some of the problems I have are:

Hi all
I would like to learn LINQ in great depth, not just "usual" use but how to
do just about everything :-) So far I have found the following two books,
the first looks most interesting:

I need to create an "ad-hoc" filtering page in a web app we are
building. The page would display a number of drop down lists, text
boxes, and radio lists and allow the user to select (enter) some data
that would be used to filter the dataset we return. STANDARD STUFF.
Below is simplified version (not compete) of how we solved this with
ADO using javascript on the client to build a where clause that we
would use on our SQL SELECT...

I am trying to set up a dynamic search using linq. I believe the syntax is
correct, but cannot confirm it because when I try to cast my
Session from a List<to IQueryable<>, I get a cast error
“Unable to cast object of type System.Collections.Generic.List to type
System.Linq.IQueryable”. Is there a way to cast List<to IQueryable<>, or is
there a different way I need to be doing this?

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
