I have a list called
private List <BasePopulation> Population=new List <BasePopulation>();
The problem may be that
Clear is not doing what you think it is.
Clear simply marks the
List as being empty without resizing the internal array that it uses behind the scenes. It will, however, remove all references to the individual
BasePopulation instances. So if no other data structure has a reference to them they will be eligible for garbage collection. But, it will not reduce the size of the
List directly. I just verified this using ILSpy.
You have two options.
Population = null. This will unroot the entire object instance making it eligible for garbage collection.
TrimExcess on this
List. This will resize the internal array.
