How to access a variable from a class from another in C#?
I am new in C# so I know it's a rookie question. I've been searching on this site similar questions but didn't find any.
I have two forms: MainForm and EditForm . MainForm has a class instance like in this code:
public partial class Form1 : Form
{
...
RSSSourcesLibrary NewsSourcesCollection = new RSSSourcesLibrary();
...
}
(the RSSSourcesLibrary class is defined somewhere else, in a third file)
How can I access NewsSourcesCollection from EditForm?

@Magnus yes. An instance of EditForm is created in a MainForm event handler. I want to be able to acces NewsSourcesCollection from an event handler in EditForm

Since you are creating the EditForm from the MainForm, you need to mark it as owner (enabling you to access the owner property from EditForm), while creating it in MainForm
Creating EditForm in MainForm
EditForm editForm = new EditForm();
editForm.ShowDialog(this);
Accessing from Edit Form
var value = ((MainForm)this.Owner).NewsSourcesCollection;
Where NewsSourcesCollection is declared as Public Property in MainForm
