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 ;
 }
 }
