我为对象添加了一些扩展数据，想通过护展数据的组码来过滤选择集，不知道能不能实现
程序代表码大概是这样：
Sub SelExtendData() Dim spt(2) As Double, ept(2) As Double
Dim aLine As AcadLine
spt(0) = 0: spt(1) = 0
ept(0) = 10: ept(1) = 10
Set aLine = ThisDrawing.ModelSpace.AddLine(spt, ept)
Dim xDataType(1) As Integer
Dim xDataValue(1) As Variant
xDataType(0) = 1001: xDataValue(0) = "Jika"
xDataType(1) = 1000: xDataValue(1) = "DGX"
aLine.SetXData xDataType, xDataValue
Dim sSet As AcadSelectionSet
Dim FilterType(0) As Integer
Dim FilterData(0) As Variant
FilterType(0) = 1001: FilterData(0) = "jika" ’这一句组码可以生成选择集
Set sSet = CreateSelection("aa") 'CreateSelection(''aa")是一个自定义的创建选择集函数
sSet.Select acSelectionSetAll, , , FilterType, FilterData
MsgBox sSet.Count
sSet.Delete
End Sub
我的问题是想通过 FilterType(0) = 1000: FilterData(0) = "DGX" 这一句或其他方式定义选择集
有没有高手遇到过这样的问题，麻烦给个合理的定义选择集过滤条的方法，谢谢！
