public static long GetTotalMemory(
    bool forceFullCollection


  • forceFullCollection
    Type: System.Boolean
    true to indicate that this method can wait for garbage collection to occur before returning; otherwise, false.

Return Value

Type: System.Int64
A number that is the best available approximation of the number of bytes currently allocated in managed memory.


If the forceFullCollection parameter is true, this method waits a short interval before returning while the system collects garbage and finalizes objects. The duration of the interval is an internally specified limit determined by the number of garbage collection cycles completed and the change in the amount of memory recovered between cycles. The garbage collector does not guarantee that all inaccessible memory is collected.
