权限表如图：

此主题相关图片如下：1.jpg

我现在建了3个内部函数

①shouquan

Dim dt As DataTable = DataTables("授权")
Dim dr As DataRow
dr = dt.Find("导航分组 = \'" & args(0) & "\' And 功能模块 = \'" & args(1) & "\' And 流程 = \'" & args(2) & "\'")
If dr.IsNull("用户") = False Then
    Dim nms() As String = dr("用户").Split(",")
    For Each nm As String In nms
        If nm = _UserGroup Then \'如果授权用户包括登录用户所属的分组或其用户名
            Return True \'返回True
        End If
    Next
End If
Return False

②shouquan导航分组

Dim dt As DataTable = DataTables("授权")
Dim drs As List(of DataRow)
drs = dt.Select("导航分组 = \'" & args(0) & "\'")
For Each mr As DataRow In drs
    If mr.IsNull("用户") = False Then
        Dim nms() As String = mr("用户").Split(",")
        For Each nm As String In nms
            If nm = _UserGroup Then \'如果授权用户包括登录用户所属的分组或其用户名
                Return True \'返回True
            End If
        Next
    End If
Next
Return False

③shouquan功能模块

Dim dt As DataTable = DataTables("授权")
Dim drs As List(of DataRow)
drs = dt.Select("功能模块 = \'" & args(0) & "\'")
For Each mr As DataRow In drs
    If mr.IsNull("用户") = False Then
        Dim nms() As String = mr("用户").Split(",")
        For Each nm As String In nms
            If nm = _UserGroup Then \'如果授权用户包括登录用户所属的分组或其用户名
                Return True \'返回True
            End If
        Next
    End If
Next
Return False

shouquan是为了判断 3列的权限

shouquan导航分组 是为了判断是否有【导航分组】权限 不需要再判断后面2列

shouquan功能模块 类似

请问这样是否合理？？

哦 这样

还是分 3个内部函数是把
