首先，请不要使用转到 - 实际上忘记它存在了几年，到那时你应该更好地了解何时适合使用它。

相反，尝试这样的事情：

First off, don't use Goto - in fact forget it exists for a couple of years, by which time you should have a better idea of when it is appropriate to use it.
Instead, try something like this:

private void button1_Click(object sender, EventArgs e)
    {
    if (MessageBox.Show("Enter more data?", "Data Saved", MessageBoxButtons.YesNo) == DialogResult.No)
        {
        Close();
        }
    }

如果用户不想输入更多数据，那将关闭您的表单。

Which closes your form if the user doesn't want to enter more data.
