How to access a form element from a class?

Question

C++ / C#

Good day.
I am using WinForms C#. There is label1 on the form, there is a separate class, suppose it is called Test.cs. How can I access Form1's label1.Text from this class (Test)?

Answer 1

have label1 set the access modifier public (for example) .... and contact.

Answer 2

It is best to make a public method (or property) in the form that returns a reference to textBox1.

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
.....................
        public TextBox getTextBox()
        {
            return textBox1;
        }
    }
}
