Description

The GC.Collect method forces a garbage collector to run to free their memory. Using this method is usually not necessary and can impact your applications performance greatly as it may need to block all threads while it examines every object in memory to potential cleanup.

Non-Compliant Code Examples

static void Main(string[] args)
{
  GC.Collect();
  GC.Collect(42, GCCollectionMode.Optimized);
}
