How to read from memory I / O port in .Net?

Question

Can standard pointers in .Net do this? Or need to resort to P / invoke?

Note that I'm not talking about object references; I am talking about actual C # pointers in unsafe code.

Answer 1

C #, as a managed and protected run-time mechanism, does not allow access to low-level hardware and memory locations associated with the actual hardware are not available.

You will need to use a port driver or write your own in C ++ or C using the appropriate Windows API to access memory mapped I / O areas. This will work in a lower ring than C # programs can use.
