Dim dt As DataTable = DataTables("在籍学生信息")
Dim Filter As String = "[班级] = \'" & e.Node.name & "\' And 学期 = \'" & e.Node.ParentNode.name & "\'"
Dim drs As List(of DataRow) = dt.Select(Filter,"")
For i As Integer = 0 To drs.Count - 1
    If e.Form.Controls.Contains("Lable" & i+1) Then
        e.Form.Controls("Lable" & i+1).text = drs(i)("姓名")
        e.Form.Controls("PictureBox" & i + 1).Image =  GetImage(drs(i)("照片"))
    End If
Next
For i As Integer = drs.Count To 7
    If e.Form.Controls.Contains("Lable" & i+1) Then
        e.Form.Controls("Lable" & i + 1).text = ""
        e.Form.Controls("PictureBox" & i + 1).Image = Nothing
    End If
Next

e.Form.Controls("Label1").text = drs.count
e.Form.Controls("Label2").text = dt.Compute("count(性别)",Filter & " And 性别 = \'男\'")
e.Form.Controls("Label3").text = dt.Compute("count(性别)",Filter & " And 性别 = \'女\'")


出现：

翻译错误："Contains"不是"ControlCollection"的成员。

错误代码： If e.Form.Controls.Contains("Lable" & i+1) Then

请师傅指点

Contains 不对，应该：

 
If e.Form.ExistControl("Lable" & i+1) Then
