You can easily access a public value once the form is closed that
contains the assignment you make in the form. So let's say you have a
main form:

   public partial class MainForm : Form
   {
       public MainForm()
       {
           InitializeComponent();
       }

       private void button1_Click(object sender, EventArgs e)
       {
           WinForm wf = new WinForm();
           if (wf.ShowDialog().Equals(DialogResult.OK))
               MessageBox.Show(wf.SomePublicString);
       }
   }

You can see the wf.SomePublicString is available to you... Here is the
WinForm:

   public partial class WinForm : Form
   {
       public string SomePublicString
       {
           get { return somePublicString; }
           set { somePublicString = value; }
       }
       private string somePublicString = string.Empty;

       public WinForm()
       {
           InitializeComponent();
       }

       private void button1_Click(object sender, EventArgs e)
       {
           SomePublicString = "Hello World!";
           DialogResult = DialogResult.OK;
       }
   }

Hope that helps...

Viepia,

   Why not expose the value through a property on the instance?  Then,
after the call to ShowDialog is made, the caller can access the value
through the property on the instance that ShowDialog was called on.

Hi,

A simple public property will do:

MyForm f = new MyForm();
if ( f.ShowDialog() == DialogResult ...)
{
  DoSomething( f.MyProperty);
}
