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?

I recently stumbled across a pretty interesting LINQ to SQL question and
wonder, whether anybody might have an answer. (I'm doing quite some
increasing LINQ evangelism down here in Germany.).
Assume I want to select rows from a database and check whether a specific
column contains keywords from a list of keywords. The following works just
fine:
List<stringsearchTerms = new List<string>() { "Maria",
"Pedro" };

Hi
I am currently building an application on .NetCF 3.5 in C#. The
application needs to process xml files. I am thinking about using LINQ
to process XML. I wrote a piece of code to modify the specified
element's value.
XmlReaderSettings settings = new
XmlReaderSettings();

Hello,
I'm using LINQ to access a SQL Server database. The user needs to be able to
duplicate a record. Is there an easy way to do this? I rather not have to set
each property from one to the other. I need to copy all the relationships
too.
Thanks for any help, I really appreciate it.
Thanks,

Hi all:
after reading different places/sites about linq... I ran into these questions:
1. What framework do we need to run linq ?
(does it depend on what version of visual studio we have?)
how about vs2008?
is it different name space or framework for linq xml or linq sql? (
2. do we need to have references to what linq's dlls. or namespaces?
system core?
3. what name spaces are needed?

Hi, all,
If I write follow code in c# method. The IDE will compile it to a complex construct method of System.Linq.Expression.
Expression<Func<int>ex = () =10;
will be compile to:
Expression<Func<int>ex = Expression.Lambda<Func<int>(Expression.Literal(10))
It is so smart. I can travel in this expression tree. I can do some smart abilities on this design.
Now, I want write a console application. If user input follow string from console,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
