I'm starting to learn C# (by my own, so far, with a teacher soon).
I'd like to create a linked list able to store 2 variables.

I'm working with TCP connections, and one of these variables is obviously the client socket, which is the only one I'm storing right now:

C# code:

---

private LinkedList<Socket> list = new LinkedList<Socket>();

---

C# code:

---

foreach(Socket s in list) //cmd

---

C# code:

---

while (list.Count != 0) list.RemoveFirst(); // this is using LinkedList

---

You can't do a RemoveFirst on a Dictionary.

Why would you need pointers?

Anyway, http://msdn.microsoft.com/en-us/library/5tbh8a42.aspx would suffice (just create a List<KVP<String, Socket>>, or swap String & Socket if you want the latter to be the key.).

Very interesting. I'll try that later.
Thanks.

There is no reason why you can't use LinkedList with your own class that holds the Socket and whatever additional item(s) you want.

I think you are misinterpreting that there are "no pointers" in C# to also mean there are no references, which isn't the case.  What that means, in essence, is you can't easily do funky pointer math and you shouldn't count on being able to know how your data types are laid out on the low level.  You may wish to read this.

Interesting. Actually, since it's the first time I'm using an object-oriented language (I've "used" Python once, but I don't think that counts), this things of classes, methods, events, they are still a bit messed in my head.
I'm not really worried about it now, because soon I'll have some classes and (hopefully) this mess will be cleared. I just wanted to start coding a little bit using what I know from C and some extra new stuff.

In C, I could do this:

C code:

---

struct client {
    int socket_descriptor;
    char[10] name;
    struct client *next;
    struct client *prev;
}
