How can I pass values from one form to another?

Question

Consider the situation where I have two windows forms, say F1 and F2. After using F1, I have now called F2.ShowDialog().

Answer 1

Has anyone considered simply passing the value to the form in the tag attribute.

Form newForm = new form();
newForm.Tag = passValue;
newform.showmodal();

when newform is shown the load (or any other) routine can use the data in tag

public void load()
{
  if (this.Tag.length > 0)
  {
     // do something with the data
  }
}
