求助：C#中 win窗体里 多个textbox值的存取

Liststring list = new Liststring(); void GetAllTxt() { foreach (Control Control in Controls.OfTypeControl()) { if (Control.GetType().Equals(typeof(TextBox))) list.Add(Control.Text.Trim()); else GetTxt(Control, list); } //list里面装载了所以窗体的控件类型为TextBox的值 } void GetTxt(Control Control, Liststring list) { foreach (Control MyControl in Control.Controls.OfTypeControl()) { if (MyControl.GetType().Equals(typeof(TextBox))) list.Add(MyControl.Text.Trim()); else GetTxt(MyControl, list); } }
