I am having a problem using the NameValueCollection type.
If I remove one of the items while iterating through an
collection of this type, I end up with an exception.
This exception is:
Collection was modified after the enumerator was
instantiated.
This happens when it attempts to continue through the
enumeration.

I always use NameValueCollection. But I read an article says the only
differece between Hashtable and NameValueCollection is that
NameValueCollection could accept more than one value with same key? I am not
quite understand this. And I think NameValueCollection's Set is a nice
method. If I use HashTable, how can I update a item in it? Do I have to
check if it exists, and remove and add it again?
Thanks.

Problem: often times I deal with querystring-formatted strings w/o the
actual HttpRequest object involved.
Solution: the function accepts such a querystring-type string and outputs a
NameValueCollection object

We are trying to serialize the Request.ServerVariables collection
(NameValueCollection) to an XML formatted string, to insert into a database.
The problem we are running into is that most of the example that we find
discuss writing to a file. Does anyone have a simple function to do this?
We would also like to deserialize the string from the database back into a
NameValueCollection.

For some unknown reason (user error?), I cannot get a NameValueCollection to
persist in the app.config file.
Unlike other settings, I cannot get the String Collection Editor GUI to
allow my to add/edit any values for a setting with type NameValueCollection.
Nor can I get a NameValueCollection to persist to the User Settings via code
using a simple C# Console App...
Is this a user error or ?

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...
