C# Access Method of Form1 on Form2

Question

I have 2 Forms in my project. Form1 is the main Form. There I have a button to open Form2, a ListView and a method to call a url and feed the ListView with data it gets from

Answer 1

Define a property on Form2 to allow the access of the result

// In Form2
public string Url { get { return urlTextBox.Text; } }

In Form1

var form2 = new Form2();
form2.ShowDialog(this);
string url = form2.Url;

Note: unless Show() the ShowDialog() method waits until form2 is closed.

The ShowDialog argument this is the owner of the form to be opened. It binds form2 to form1 and makes it always appear on top of form1.
