How to make a Class object global??

[suguimoto]

Hi! I would like to know if it´s possible to make a class object global. Just like if I declared once, and a lot of classes can work with it, keeping the same values. Because if I instantiate an object for every class... the values go blank =/ (Class obj = new Class()) Thnx

Hi, make function and property as static so that you can call from anywhere without creating instance -- modified at 6:39 Friday 7th July, 2006

Yeah something like: public static decimal ComputeInterest() { // Code here }

If you actually need an object instead of just static methods in a class, you can make a singleton:

public class Singleton {

private Singleton instance;

private Singleton() {}

public Singletton GetInstance() {
if (this.instance == null) {
this.instance = new Singleton();
}
return this.instance;
}

}

--- b { font-weight: normal; }>

private static Singleton instance; public static Singletton GetInstance(); might though. Also, I read once, that private static Singleton instance = new Singleton(); would be gauranteed to be accessed in order and is not subject to threading issues. Whereas this.instance == null can cause threading problems. A man said to the universe: "Sir I exist!" "However," replied the Universe, "The fact has not created in me A sense of obligation." -- Stephen Crane

Yes, correct.

Yes, to make it thread safe you need locking. --- b { font-weight: normal; }
