How to force garbage collector to run?

Question

System.GC.Collect() forces garbage collector to run. This is not recommended but can be used if situations arise.

It is not recommended to call gc explicitly, but if you call

GC.Collect();
GC.WaitForPendingFinalizers();

It will call GC explicitly throughout your code, don't forget to call GC.WaitForPendingFinalizers(); after GC.Collect().

GC.Collect() 

from MDSN,

Use this method to try to reclaim all memory that is inaccessible.

All objects, regardless of how long they have been in memory, are considered for collection; however, objects that are referenced in managed code are not collected. Use this method to force the system to try to reclaim the maximum amount of available memory.

GC.Collect()

GC.Collect();

Keep in mind, though, that the Garbage Collector might not always clean up what you expect...

You do not want to force the garbage collector to run.

However, if you ever did (as a purely academic exercise, of course):

GC.Collect()

I think that .Net Framework does this automatically but just in case. First, make sure to select what you want to erase, and then call the garbage collector:

randomClass object1 = new randomClass
...
...
// Give a null value to the code you want to delete
object1 = null;
// Then call the garbage collector to erase what you gave the null value
GC.Collect();

I think that's it.. Hope I help someone.
