Hi List,
I have a question on collection synchronisation. For example I have an
ArrayList called myList and the code is like this:
lock (myList.SyncRoot)
{
// do update on myList
Monitor.PulseAll(myList.SyncRoot);
}

Thread Safety

Hi,
I am converting an existing native C++ program making heavy use of STL
to C#2.0 with STL usage replaced by the new generic collections. The
conversion has gone well to the point where I am replacing an STL map
instance by a System.Collections.Generic.SortedDictionary instance. In
need the collection to be ordered, and to have o(log(n)) look up - that
is fine so far SortedDictionary.TryGetValue does the job. I also need

Hi,
Does System.Collections.Generic.Queue not have a Synchronized
method because it is already in effect synchronized, or is the
Synchronized functionality missing from
System.Collections.Generic.Queue? Putting it another way can I
safely replace a
System.Collections.Queue.Synchronized(myUnSynchronizedQueue) with a
System.Collections.Generic.Queue while porting a working 2003 project?
Thanks,

What is the recommended pattern for implementing a synchronized
(thread-safe) class that inherits from Collection<T>? For example, I want
to implement a SyncRoot property . I do see where I can override
(protected) the methods InsertItem, RemoveItem, ClearItems, and SetItem.
However, I do not see an override for GetItem.
Kindest regards,
Michael

Hi,
I want to create a collection of objects that will be used as a
property of another object. So for example if I had a Customer object,
I would like to have an AddressCollection property within that object.
That AddressCollection property would contain one to many Addresses for
each Customer and the Address object would have properties such as
Street, City, State, etc.
I am struggling with what interface to use to do this. I've...

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...

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...
