How to prevent string being interned
c#, memory
Solution
If you need to remove the strings from memory for security reasons, use `SecureString`.
Otherwise, if there are no references to the string anywhere, the GC will clean it up anyway (it will no longer be interned) so you don't need to worry about interning.
And of course, only string literals are interned in the first place (or if you call String.Intern() as noted above by Petr and others).
Problem
My understanding (which may be wrong) is that in c# when you create a string it gets interned into "intern pool". That keeps a reference to strings so that multiple same strings can share the operating memory. However I am processing a lot of strings which are very likely unique, and I need to completely remove them from operating memory once I am done with each of them and I am not sure how the cached reference is going to be removed so that garbage collector can just remove all the string data from memory. How can I prevent the string from being interned in this cache, or how can I clear it / or remove a string from it so that it surely get removed from operating memory?
