Returns the number of times garbage collection has occurred for the specified generation of objects.

public:
 static int CollectionCount(int generation);
public static int CollectionCount(int generation);
static member CollectionCount : int -> int
Public Shared Function CollectionCount (generation As Integer) As Integer

Parameters

generation
Int32

The generation of objects for which the garbage collection count is to be determined.

Returns

The number of times garbage collection has occurred for the specified generation since the process was started.

Exceptions

generation is less than 0.

Remarks

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 CollectionCount immediately after calling Collect. The next time you need to call Collect, compare the current value returned by CollectionCount 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.
