[求助]使用vb.net2003引用ActiveX 开发时，为何选择集总是不能产生，详情进入？

wcbao

Dim gpCode(0) As Integer
Dim dataValue(0) As Object
gpCode(0) = 39
dataValue(0) =2200000

Dim groupCode As Object, dataCode As Object
groupCode = gpCode
dataCode = dataValue
Dim ssetobj As AcadSelectionSet
ssetobj = AcadDoc.SelectionSets.Add("test")
ssetobj.Select(AcSelect.acSelectionSetAll, , , groupCode, dataCode)

以上代码总在select 处提示filter无效，可是在vba中是可以的，请高手指教，如何修改vb.net中的代码。
