[Solved] How does string works in c#? [closed]

Question

review String Interning or .Net String Intern table or CLR Intern Pool.
Basically, the Common Language Runtime (CLR) maintains a table of [unique] string values, and whenever you manipulate a string in your code, the CLR examines this intern table to see if the new value you are trying to create is already in there or not. If it is, it just reassigns the variable you are modifying to point to that entry in the intern pool. If not, it adds the value to the pool and returns that new reference. Old values in the pool, no longer referenced by variables, get garbage collected.
