There are a piece of code

 
Int i1=2; 
The object o1=i1; 
The object o2=o1; 

Object. ReferenceEquals (o1, o2). Dump ();//true 

O1=5; 

O1. Dump (" o1 ");//return 5 
O2. Dump (" o2 ");//return 2 

The above code, i1 for int value types, then assigned to the object o1 for packing process and become a reference type, then o1 assigned to o2 (according to the characteristics of a reference type, the actual values should be stored in a Heap Heap, Stack and the Stack to store reference address, the result should be consistent), would you please tell me why why to o1 to assign a value does not affect the value of o2?

O1=5;//this is your new packing
