How to handle multithread on singleton pattern ?

 

[Skydiver]

Inside each public method, getter/setter, and event raise method of your singleton object you would wrap the code with a critical section (aka lock). Critical sections will lock out other threads but allow the same thread to continue to use the singleton. Other threads trying to access the object will wait until the critical section is released.

lock statement - synchronize thread access to a shared resource - C#

Use the C# lock statement to ensure that only a single thread exclusively reads or writes a shared resource, blocking all other threads until it completes.
