主题：[求助]权限代码 可否优化!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

我觉得后面两个，这样才合理：
 
'shouquan导航分组
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 Is Null And 流程 Is Null")
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
 
'shouquan功能模块
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 Is Null")
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
