用vb.net如何 编程遍历页面上所有TextBox控件并给它赋值为string.Empty？

例如:asp.net遍历的这种方式 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 ; } }

For Each ctl As Control In Me.Controls If TryCast(ctl, TextBox) <> Nothing Then Dim txt As TextBox = TryCast(ctl, TextBox) txt.Text = "" End If
