'Declaration Public Shared Function CollectionCount ( _ generation As Integer _ ) As Integer
- Type: System.Int32
The generation of objects for which the garbage collection count is to be determined.
Return ValueType: System.Int32
The number of times garbage collection has occurred for the specified generation since the process was started.
If you implement your own resource management, you might need to force garbage collection periodically by calling the Collect method. Because this is an expensive operation, you can improve performance by skipping the call when a garbage collection has occurred recently. Save the value returned by immediately after calling Collect. The next time you need to call Collect, compare the current value returned by to the saved value. If the two values are equal, no collection has occurred in the interim and it is reasonable to call Collect again.
