ArrayList, can't add ?

[vertigo]

Hello
When i try:

MyClass myClassObject = new MyClass();
ArrayList myArrayList;
myArrayList.Add (myClassObject) ;

where MyClass is my own class What's wrong ?
Thanx
Michal

[gmiley]

ArrayList myArrayList = new ArrayList();

or

You could go a step further and create a myClassObjectCo llection class:

public class MyClassCollecti on : System.Collecti ons.CollectionB ase
{
// implement the methods you need here, such as: Add, Remove, etc...
}

MyClass myClassObject = new MyClass();
MyClassCollecti on myClassObjects = new MyClassCollecti on();

myClassObjects. Add(myClassObje ct);

Michal,

The reason this doesn't work is because you haven't created an array
list to place your class in. The line that reads:

ArrayList myArrayList;

Should read:

ArrayList myArrayList = new ArrayList();

Hope this helps.

you have to create new arraylist

Try this code
MyClass myClassObject = new MyClass();
ArrayList myArrayList = new ArrayList()
myArrayList.Add (myClassObject) ;
