  public partial class Form1:form  //parent Form    {public        string name= "";        Public Form1 ()        {            InitializeComponent ();        }        private void Newbtn_click (object sender, EventArgs e)        {            Form2 Form2 =new Form2 ();            Form2. ShowDialog (); NOTE this! Must is ShowDialog () not  Show ()!            if (Form2. DialogResult = = DialogResult.OK)            {                TextBox1.Text = form2.name;                Form2. Close ();}}    }

public partial class Form2:form//son Form    {public        string name       {            set {TextBox1.Text = value;}            get {return textbox1.text;}        }        Public Form2 ()        {            InitializeComponent ();        }        private void OK_Click (object sender, EventArgs e)        {            if (TextBox1.Text = = "")            {                MessageBox.Show (" Input!
