Question

I have a class Node,then I created my tree node in my main
like this:

static void Main(string[] args)
{
  Node IProot = new Node("ANY-IP");           
}

I want to have access to this Node all the times even when I will go through another function(setting IProot global) for example I want to have

public static alarm generalize(alarm one,alarm two)
{       
   //some code
}

instead of

public static alarm generalize(alarm one,alarm two,Node IProot)
{       
  //some code
}

if this is totally wrong what should I do?

Because I don’t have access to IProot, I have to get it as an input to my function so that I can code with IProot,but it is much better for me to not get it as an input.
I tried static Node where I defined IProot in the main, but that resulted in an error. I also tried static class Node for my class, again no result.

Try this:

static Node IProot;

static void Main(string[] args)
{
    IProot = new Node("ANY-IP");
}

This instantiates the IProot object in your application’s Main method, and will allow that instance of the object to be accessible in the methods in your class.
