C# GC.Collect() Method: Force Garbage Collection in .NET

GC.Collect() is a method in .NET that forces garbage collection. It is used to reclaim memory occupied by objects that are no longer in use.

Garbage collection in .NET is automatic and managed by the runtime. However, there might be situations where it is necessary to explicitly call GC.Collect() to release memory in a timely manner, such as when dealing with large objects or when memory usage needs to be controlled.

Calling GC.Collect() initiates a garbage collection cycle, which involves marking objects that are still in use, compacting memory, and freeing memory occupied by objects that are no longer reachable. Keep in mind that calling GC.Collect() does not guarantee immediate memory release, as the garbage collector runs on its own schedule.

It is generally recommended to let the garbage collector handle memory management automatically, as it is optimized for efficient memory usage. Explicitly calling GC.Collect() should only be done when there is a specific need and after careful consideration of the potential impact on performance.
