代码贴全了吗
我试了试 可以 不知道是不是我理解错了 测试代码如下：
public partial class Form3 : Form
{
Form form = null;
public Form3()
{
InitializeComponent();
}

private void OK_Click(object sender, EventArgs e)
{
form.Dispose();
form.Close();
}

private void button1_Click(object sender, EventArgs e)
{
form = new Form();
TextBox textbox1 = new TextBox();
Button button1 = new Button();
Button button2 = new Button();
form.AcceptButton = button1;
button1.Click += new EventHandler(OK_Click);
form.CancelButton = button2;

button1.Location = new Point(0, 100);
button1.Text = "关闭";
button2.Location = new Point(100, 100);
textbox1.Location = new Point(0, 0);

form.Controls.Add(textbox1);
form.Controls.Add(button1);
form.Controls.Add(button2);

form.ShowDialog();
}
}

一旦调用了ShowDialog()
就必须要先把这个ShowDialog()出来的窗口 事情做完
才能对其他的窗体进行操作
