请编程遍历页面上所有TextBox控件并给它赋值为string.Empty？(webform&winform)

webform:

 

 

Code

   
      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:

Code

    
      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 ;
}
} 

恶寒！刚刚就看了哈首页的要求，可能是无意点了哈那四行字 怎么就发到首页去了，尴尬！
