HI...

I'm a beginner in C# and have a question.

This is the from class

namespace WindowsFormsApplication
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
    }
}

This is the working class named Class1...

namespace WindowsFormsApplication
{
    class Class1
    {
    }
}

I want to modifer added text to listbox from Class1? How can I do it?

You need to implement some non-private (internal) method/property in the form; better yet, implement some interface in the form which does that. The interface should be visible to Class1, in all cases, you need your Class1 need to have to form instance reference.

For more detail on my approach, other options and the discussion, see this: How to copy all the items between listboxes in two forms[^].

This discussion is about two different forms, but it covers your case as well: one form and some separate class.
