Thanks for your explantion, I am a green hand, so maybe I need more time
the understand it.
I clearly know Mono.cecil can do everything to a C# program, because it can
read the original program and create new instructions to it.
There is another question is: can it combines two programs into one or
introduces some part of a program to another one?For example:
There is a program like:
Assembly A contains:
class program 1
{
public main(){}
}
Assembly B contains:
class program 2
{
variable a;
public fun(){ a...}
}
I wonder how to introduce the fun() in program 2 to program 1. if this can
be done, I can surely use
Mono.cecil to let main() call the fun(). Now my initial idea is to create
the variable and fun() in program 1, just
the same to program 2
but it feels a bit strange, is there a way to introduce them to program 1?
