You'll have to add a property to your child form, and then instead of closing the child form, hide it, then the object will still be available from the parent form, and you'll be able to access the property, disposing of the child form after.

In C# it will look something like this (I'm using a string as example, but you'd obviously modify it to fit in with your requirements:
In your child form

private string returningValue = string.empty;
 
public string SelectedValue
{
    get { return returningValue.Trim(); }
}
 

In your exit code it should look similar to this:

.
.
.
returningValue = <the value you want to access from the parent form>;
this.Hide();
 

Then in your calling form it should look like such:

.
.
.
frmMyChildForm form = new frmMyChildForm();
 
//using ShowDialog() because you want the child form to retain focus, 
//instead of this code just running through
form.ShowDialog();
 
//Access the SelectedValue property of our form object
MessageBox.Show("The selected value is " + form.SelectedValue);
 
//Close (dispose) our form object
form.Close();
