Question

I’m working on my very first project outside the college.
I have two classes. In first one I have a method which adds strings to an arraylist.
In the second class I would like to access the arrayList from the method in previous class, and get elements of it.

How could I do that ?
Thank you for helping.

Unless you’re using .NET 1.1 i would avoid ArrayLists and use their strongly typed counterparts List<T>.

You need to make the method public in class 1. Then you can access it from class 2 if it is static or if you have an instance of class 1.

For example:

public class Class1{
    public List<String> getList()
    {
        // create the list and return it
    }
}

public class Class2{
    Class1 firstClass{ get;set; }
    void foo()
    {
        // now you can access the List<String> of class1 via it's instance
        List<String> list = firstClass.getList();
        foreach(String s in list)
        {
            // do something
        }
    }
}
