When i do
int k=3;
where in the reflector can i find the pseudo statement?
Object k = new Int32();
where can i find the value assign?
Even though primitive types inherit from Object, the .net Framework treats them in a special way. An int is an int and treated using functions like ldc.i4 (loads a 32-bit constant onto the stack).
In situations where an object is needed, an int is indeed cast to Object through a process called boxing.
