遍历页面上所有TextBox控件并给它的Enabled赋值为false

private void FindSelecedControl(Control control) { if (control is TextBox) {             TextBox txt = (TextBox)control;             txt.Enabled = false;         } else { for (int i = 0; i < control.Controls.Count; i++) {                 FindSelecedControl(control.Controls[i]);             }         }     }

页面调用方法：

   foreach (Control control1 in this.Form.Controls)             {                 FindSelecedControl(control1);             }
