用COM(VB.NET)与CAD连结的选择集过滤间题

liaoost

请问如何在VB.NET下以COM方法跟CAD连结.取得选择集
目前程序如下
Dim Cad As Autodesk.AutoCAD.Interop.AcadApplication
Cad = New Autodesk.AutoCAD.Interop.AcadApplication
Dim Open_Cad_File As AcadDocument = Cad.Documents.Open("C:\0\0.dwg")
Dim ssRev As Autodesk.AutoCAD.Interop.AcadSelectionSet
Dim ssRevs As Autodesk.AutoCAD.Interop.AcadSelectionSets
Dim FilterType(0 To 3) As Object
Dim FilterData(0 To 3) As Object
FilterType(0) = -4
FilterData(0) = "<AND"
FilterType(1) = 1
FilterData(1) = "REV"
FilterType(2) = 0
FilterData(2) = "TEXT"
FilterType(3) = -4
FilterData(3) = "AND>"
ssRevs = Cad.ActiveDocument.SelectionSets
ssRev = Cad.ActiveDocument.SelectionSets.Add(“REV”)
ssRev.Select(AcSelect.acSelectionSetAll, , , FilterType, FilterData) ← Error:无效的自变量 FilterType (于 Select 中)
请问FilterType, FilterData 要如何处理?
谢谢.
