請編程遍歷頁面上所有TextBox控件並給它賦值爲string.Empty？(webform&winform)

webform:

 

 

 foreach (Control control in this.Form.Controls)

        {

            if (control is System.Web.UI.WebControls.TextBox)

            {

                TextBox txt = (TextBox)control;

                txt.Text = "fdsafds";// string.Empty;

            }

        }

 

 

winform:

foreach (System.Windows.Forms.Control control in this.Controls)
{
if (control is System.Windows.Forms.TextBox)
{
System.Windows.Forms.TextBox tb = (System.Windows.Forms.TextBox)control ; 
tb.Text = String.Empty ;
}
} 

惡寒！剛剛就看了哈首頁的要求，可能是無意點了哈那四行字 怎麼就發到首頁去了，尷尬！
