If e.DataCol.name = "aaa" Then
    Dim ary() As String = {"1", "2", "3", "4", "5", "6"}
    If array.IndexOf(ary, e.DataRow("一")) >= 0 AndAlso array.IndexOf(ary, e.DataRow("二")) >= 0 AndAlso array.IndexOf(ary, e.DataRow("三")) >= 0 Then
        e.DataRow("aaa") = "√"
    Else
        e.DataRow("aaa") = Nothing
    End If
    
End If

在执行时提示:编译错误: "e"是"private",因此它在此上下文中不可访问

错误代码 If e.DataCol.name = "aaa" Then

这是怎么回事呢,求指教?
