我在后台动态添加n个textbox,现在我想用for循环获取它们的值...
生成控件的代码:
For i = 1 To Int(TextMany.Text)
                Dim textbox As New TextBox
                Dim label As New Label
                Dim text As New TextBox
                Dim tex As New TextBox
                tex.ID = "tex" & i
                tex.Enabled = False
                tex.Text = "http://" & Request.QueryString("address")
                text.ID = "text" & i
                text.Width = 60
                Panel1.Controls.Add(label)
                Panel1.Controls.Add(tex)
                Panel1.Controls.Add(textbox)
                Panel1.Controls.Add(text)
我用button单击事件获取textbox的代码:
            Dim txt As TextBox
            txt = CType(Me.FindControl("textbox" & i), TextBox)
            txt.Text = CType(Me.FindControl("textbox" & i), TextBox).Text

但是报错:未把控件引至对象事例..........

foreach(System.Windows.Forms.Control   ctl   in   this.Controls)

For i = 1 To Int(TextMany.Text)
            moviescat = "第" & i & "集"
            For Each elem In Request.Form.AllKeys
                If elem.Contains("textbox" & i) Then
                    txtboxValue = Request(elem)
                    moviesaddress = "http://" & Request.QueryString("address") & txtboxValue
                     = "insert into movies_cont(Movies_Name,Movies_Cat,Movies_Address) values('" & TextName.Text & "','" & moviescat & "',' " & moviesaddress & "   ')"
                    comm1.ExecuteNonQuery()
                End If
            Next
        Next
这样可以获取动态生成的textbox的值..........但是又发现个问题 当Int(TextMany.Text)小于10时正常把数据存到数据库.....但是Int(TextMany.Text)大于10时问题来了......
假如Int(TextMany.Text)=12时
