I recently switched over from C++ to C# and I am wondering how I would do the equivalent in c#. In C++ I could have done this:

Enemy *enemy; 

enemy = new Enemy("Goblin", 20, 20);

In c#, I tried the pointer methond and using a delegate and both failed. The thing is I have multiple enemys in my Text RPG and I need to assign a specific enemy to my enemy pointer class so I then can preform the battle processes.

C# has references instead of C++ style pointers. So for your example, you would just do:

Enemy enemy; //enemy is a reference to an Enemy
enemy = new Enemy("Goblin", 20, 20); //the reference points to a Enemy instance in the heap

Another interesting difference is that almost everything is a reference, apart from some primitive value types (int, float, double, decimal, bool, structs, enumerations) which can be stored on the stack.

As a side note you CAN use pointers, however they are considered unsafe and you have to mark your code as such - msdn.microsoft.com/en-us/library/t2yzs44b(v=vs.80).aspx
Value types are only stored on the stack when they are local variables, otherwise they are part of an object which is stored on the heap.
@user2097371 ipavlic's sample works because in C# classes are passed by reference, not by value. An excelent article to understand this relationship is this one about the difference between Class and Struct in C# geekswithblogs.net/BlackRabbitCoder/archive/2010/07/29/…
@EtherDragon: No, references are not passed by reference unless you use the ref keyword. Passing a reference and passing by reference is two different things.
Thanks, I didn't think it would be that simple.
