c# - WinForms Close() sets DialogResult to Cancel

If I call Close() in my WinForm, it seems that even though DialogResult is None at the time, right after I call Close() I see that it is set to Cancel.

Does this sound normal?

Or even easier, you can set DialogResult just after Close. For example, assuming ValidateSettings will show the user any problems with the form or return true otherwise:

    private void btnOK_Click(object sender, EventArgs e)
    {
        if (ValidateSettings())
        {
            SaveSettings();
            Close();
            DialogResult = DialogResult.OK;
        }
    }
