GC.Collect Method (Int32, GCCollectionMode)
Forces a garbage collection from generation zero through a specified generation, at a time specified by a GCCollectionMode value.
Assembly: mscorlib (in mscorlib.dll)
Use the mode parameter to specify whether garbage collection should occur immediately or only if the time is optimal to reclaim objects. Using this method does not guarantee that all inaccessible memory in the specified generation is reclaimed.
To adjust the intrusiveness of garbage collection during critical periods in your application, set the LatencyMode property.
The garbage collector does not collect objects with a generation number higher than specified by the generation parameter. Use the MaxGeneration property to determine the maximum valid value of generation.
To have the garbage collector consider all objects regardless of their generation, use the version of this method that takes no parameters.
To have the garbage collector reclaim objects up to a specified generation of objects, use the GC.Collect(Int32) method overload. When you specify the maximum generation, all objects are collected.
