C # Memory Management optimization Imagination (ii)----skillfully use stacks

This optimization method is easy to understand, that is, for objects used only within the method, no longer allocated on the heap, but directly on the stack allocation, the method is completed immediately after the recovery, which will greatly reduce the pressure of GC.

In fact, this optimization method is the escape analysis in Java, I do not know why. NET is not introduced.
