with these unmanaged resources? How does. Net manage and release managed resources?
Automatic Memory Management and GC heap memory allocation in the original program are as follows: Find the first memory address with sufficient space (not occupied), and then allocate the memory. When the program no longer needs information in the memory, the programmer needs to manually release the memory. The heap memory is public. That is to say, all processes
GC. setxormode is invalid when GC advanced mode is enabled.
In addition, some methods such as GC. setalpha and GC. setantialias (SWT. On) automatically enable the advanced plotting mode.

Purpose: The variable is visible in multiple threads. When the variable value is changed (note that the value of the main memory
Garbage collection GC and garbage collection gcObjects recycled by the garbage collector: The Garbage Collector only recycles the memory in the managed heap. What kind of objects will be recycled? No variable reference object. Objects without variable reference can be recycled (null. When can it be recycled? Not sure. When the program needs new memory, it starts to recycle it. GC. Collect (); // manually ca
some memory-limited devices that are very sensitive to memory usage, and want the GC to be able to accurately reclaim memory, which does not care about the speed of the program. In addition to some real-time online games, it is not possible to allow a program to be interrupted for a long time. The Incremental GC is a way to reduce the impact of
, that's great. Let's try again later ." This is one of the ways the policy engine strives to ensure efficient operation.
CHARLES: A few years ago, there was a big debate about "deterministic termination". I once talked to a programmer in the C ++ development team about "deterministic termination ", hosting C ++ also now has a certain "deterministic termination ". Right? After all, C ++ has destructor.
PATRICK: C ++ is basically in a hybrid world. If objects are explicitly created and destroyed,

For example, some desktop games and some telecommunications exchange systems. We recommend that you use the concurrent collector.

The process by which objects disappear from this area is what we call "min
