Self Initializing Class (Beginner needs Help)

Ok i am trying to create a class i can use in each of my programs since its reusable code.

For learning purposes i'm working on a networking managemeng type program

So to start off with i have created a class that looks like this

namespace MyCompany
{

public class Network
{

public static List<Segment> holder = new List<Segment>();

public static void Main()
{

// XML Processing in here to populate holder List, it dynamically retrieves teh XML from a SOAP/Web server
}

public List<Segment> getSegments() {
return(holder);
}
public class Segment
{
// Class structure to hold network segment name and an ArrayList of IPs for that segment
}

}


}



in my program i have or want to do something like this

MyCompany.Network network = new MyCompany.Network();

and when i do the above the hope is that the class intiailizes, runs through the Main() and popuplates the holder array so i can then do

List<Segment> segments = network.getSegments(); and my segments list has all my network segment objects already prepopulated.


The problem i am running into is the Main() for MyCompany.Network isn't running and the holder list isn't being populated.. In a simplier example i can't get Main() to run at all (even for something like just counting an int)..

I apologize i am fairly new to C#, i've looked through tutorials and none of them go through anything like this for Classes.

OK i think i figured it out

any self executing code seems to have to go into a same named method not Main()

Code:

---

namespace MyCompany {
  public class Network {
        public Network() {
                    //executes code on new MyCompany.Network();
        }
  }
}

What you did is define a Constructor.
Each class can have any number of constructors that receive different initialization variables. When you create a new instance of the class, the constructor gets called and initialices your instance. You could for example have:
public classConstructor()
public classConstructor(int ID)
public classConstructor(int ID, string Name)
...etc
