How to fill class with data c#

Question

Hi everyone. I am trying to fill class with data and use these data anywhere else on the program, where i Will need it.

 

I created this class

public class id
{
private string name; // field
public string Name // property
{
get { return name; } // get method
set { name = value; } // set method
}
}

And in form_name i tried to fill the class on this way:

private void Button_Click(object sender, RoutedEventArgs e)
{
id IDOBJE = new id();
{
IDOBJE.Name = txtshenimi.Text;
}
this.Close();
}
}

And in another form i tried to retrieve data like this:

private void Button_Click_1(object sender, RoutedEventArgs e)
{
id idobje = new id();
txtrez.Text = idobje.Name;
}

But I don't get any result. Could someone help me to clarify this, cause i am new to OOP, and don't know so much about classes, and objects.
