Question

I read many things about garbage collection like it's generation, scope etc but want to know when does the garbage collection gets triggered ? an example will be really helpful if possible.

Answer 1

Garbage collection occurs when one of the following conditions is true:

• The system has low physical memory.
• The memory that is used by allocated objects on the managed heap surpasses an acceptable threshold. This threshold is continuously adjusted as the process runs.
• The GC.Collect method is called. In almost all cases, you do not have to call this method, because the garbage collector runs continuously. This method is primarily used for unique situations and testing.
