收集表单上的所有文本框，为每个文本框生成GUID

Question

我在webform上有10个文本框，我想使用C＃为每个文本分配单独的guid。

Answer 1

像...一样的东西。

protected void Button1_Click(object sender, EventArgs e)
{
    foreach (Control MyControl in Form1.Controls)
    {
        TextBox MyTextBox = MyControl as TextBox;

        if (MyTextBox != null)
        {
            MyTextBox.ID = Guid.NewGuid().ToString();
        }
    }

Answer 2

你可以拥有

static class ControlExtension
    {
        public static IEnumerable<Control> GetAllControls(this Control parent)
        {
            foreach (Control control in parent.Controls)
            {
                yield return control;
                foreach (Control descendant in control.GetAllControls())
                {
                    yield return descendant;
                }
            }
        }
    }

并致电

this.GetAllControls().OfType<TextBox>().ToList().ForEach(t => t.ID = Guid.NewGuid().ToString());
