GC.Collect Method

Forces an immediate garbage collection of all generations.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

static member Collect : unit -> unit 

Use this method to try to reclaim all memory that is inaccessible.

All objects, regardless of how long they have been in memory, are considered for collection; however, objects that are referenced in managed code are not collected. Use this method to force the system to try to reclaim the maximum amount of available memory.

The following example demonstrates how to use the Collect method to perform a collection on all generations of memory. The code generates a number of unused objects, and then calls the Collect method to clean them from memory.
