This code is buggy.See the line:if (Monitor.TryEnter(po1) && Monitor.TryEnter(po2)) return;Imagine that the lock to po1 is true, but for po2 is false (or vice-versa).It will not return, and later will lock po1 again.So, when unlocking, it will unlock the wrong number of...

I think the start is wrong... we can pass types as parameters.A method like this:void ShowName(Type type){ Console.WriteLine(type.FullName);}can be called as:ShowName(typeof(object));or as this:ShowName(someObject.GetType());If you are trying to say that we can't...

Avoid generating strings as templates. Avoid the complicated FrameworkElementFactory. Create templates that use a delegate to create new instances, so you can use normal code to do the job.

The easiest singleton pattern is the one you used to the lock object itself.Creating any variable as static readonly and initializing it directly (or via a static constructor) will already make it singleton.Also, considering that "lock" clears all the caches, you don't need to declare the...

The problem with alternative 3 and 4 is that it is not multi-threaded.Two threads may check for null, then the two will create the new instance. The race condition only happens at the first accesses. If a single thread accesses the object, then later many threads do the access, there is no...

All classes are naturally Lazy loaded.So a better implementation will be:public class Singletonwhere T: new(){ public static readonly T Instance = new T();}You will notice that before calling the singleton class, the object will not be loaded.Surely there are...

Software Developer (Senior) Microsoft
United States United States
I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
