标题：[求助]FOXTABLE的内部函数不能处理堆栈问题吗?

如下代码执行时,FOXTABLE关闭了,

内部函数名为:addChildsfromDT

Dim ND As WinForm.TreeNode
nd=args(0)
Dim Pkey As Integer
Pkey= Cint(ND.Name)
Dim Dt As DataTable
dt=args(1)
Dim drs As  List(of DataRow)
If ND IsNot Nothing Then
    drs =DT.Select("PareKey = " & Pkey,"SortID")
    For Each dr As DataRow In drs
        nd.Nodes.Add(cstr(dr("_identify")),cstr(dr("nodetext")))
       Functions.Execute("addChildsfromDT",nd,dt)
    Next
End If
