winfrom 遍历文本框

//winform中Control是所有组件的基类

//循环文本框 缺点 文本框的名字要有规律 
for (int i = ; i <= ; i++)
            {
                Control[] coltxtSpeed = this.Controls.Find("txtbox" + i.ToString(), false);
                TextBox txtbox = coltxtSpeed[0] as TextBox;
                //Telerik.WinControls.UI.RadTextBox txtbox = coltxtSpeed[0] as Telerik.WinControls.UI.RadTextBox;
            }

//循环文本框 匿名内部类
public class txtBox
{
public Telerik.WinControls.UI.RadTextBox txtSpeed;
public Telerik.WinControls.UI.RadTextBox txtDisplacement;
public txtBox(Telerik.WinControls.UI.RadTextBox _txtSpeed, Telerik.WinControls.UI.RadTextBox _txtDisplacement)
