Timer and object?

hi i tried searching some timer tutorials but i cannot find what i am looking for.
coming from a C++ background, this assignment is my homework.
i am perfectly fluent in C++, but i dont know much about C#.
How do i go about passing the Pet object object into the static timer function?
Does anyone have tips on my code? please hlep me on this one.

here is my code:

Code:

using System;
using System.Text;
using System.Timers;

Here's a hint, since this is homework. The timer event method doesn't need to be static : it can be an instance member of a class.

Darwen.

Code:

---

Console.WriteLine("Name: " + Name + ".");

---

Can also be written as:

Code:

---

Console.WriteLine("Name: {0}.", Name);

---

Similarly for the rest. It's slightly more readable like that, especially when the number of parameters goes up:

Code:

---

Console.WriteLine ("{0} year old {1} is feeling {2}", Age, Name, Mood);
versus
Console.WriteLine (Age.ToString () + " year old " + Name + " is feeling " + Mood.ToString ());

---

i know it can be written that way. i prefer this method.
if there is any reason why your method is better. i would be glad to know. like performance? even tho thats not important in homework really, i just wanna get my homework done and be done with it so i can do my own projects

how do you mean it can be a member of the class? in C++ that would mean that the function is no good, sorry dont know how to explain it. do you mean i can just make it non-static and it will just magicly work?

okay thanks for your both replies;.

Yes, quite true. Function pointers in C++ are usually static.

This is not the case in C# (.NET). Delegates can (and most often are) created for instance methods - the delegate itself holds a pointer to the instance as well as the function.

I'd have thought it would have been quicker to try it than to reply to the post - but yes, it will work if you make your method non-static.

Then since you have an instance method it can gain access to all instance member variables of the class.

Darwen.

Thanks for your reply.

"I'd have thought it would have been quicker to try it than to reply to the post"

that might be true, but than i would leave this forum and never knowing what C# is really actually doing, and not learning anything usefull

And now you have explained it to me perfectly. Thanks alot!
