What is the counterpart of this C pointer programme in C#?

[wolle]

Please clarify.

One of the main goals of both Java and its follow-up C# is to be resilient to programmer errors. For this reason, you cannot do things like &i and *p. Explicit references and pointers were deemed dangerous and are not part of those languages. C++ takes another approach. You can still do it the C way, but you can also opt for a higher abstraction level to write safer code. In C++, you make this choice, not the language.

Learn about classes and objects in C#, and you will understand how to rewrite your example program.
