主窗体:
按钮事件:
Form2 frm = new Form2();
if (frm.ShowDialog() == DialogResult.OK)
{
textBox1.Text = frm.TextValue;
}
子窗体:
属性: public string TextValue
{
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
点击按钮事件:
TextValue = textBox1.Text;
this.DialogResult = DialogResult.OK;

在子画面里

public string value = "";
        //点击时把子画面TEXTBOX里的值付给变量value
        private void button1_Click(object sender, EventArgs e)
        {
            value = this.textBox1.Text;
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            this.textBox1.Text = "123"; 
 
        }

        //子画面关闭时把变量value的值给予主画面的textBox1
        private void Form2_FormClosed(object sender, FormClosedEventArgs e)
        {
            ((Form1)this.Owner).textBox1.Text = value;
        }

Form2 frm = new Form2();
            frm.Owner = this;

public partial class Form1 : Form
    {
        TextBox txtBox;
        public Form1()
        {
            InitializeComponent();
            this.Controls.Add(txtBox = new TextBox());
            Form2 f2 = new Form2();
            f2.ShowDialog(this);
            txtBox.Text = f2.txtBox.Text;
        }
    }

    class Form2 : Form
    {
        public TextBox txtBox;
        private Button btn;
        public Form2()
        {
            Control[] controls = 
            { 
                txtBox = new TextBox() { Location = new Point(0, 0) },
                btn = new Button() { Location = new Point(0, 20),Text="点击关闭窗口" } 
            };
            this.Controls.AddRange(controls);
            btn.Click += delegate(object sender, EventArgs e) { this.Close(); }; 
 
        }
    }
