详解GH自身的数据结构

panhao1

也许大家就要问了 为什么是structure而不是datatree
在我用C#时有提示说在运算器用datatree 在VS里用structure
估计与gh的装箱和拆箱的限制有关
再看这段代码
    Dim strip As Boolean
    ' Dim struct As New GH_Structure(Of Grasshopper.Kernel.Types.GH_Goo)
    '  For i As int32= 0 To x.count - 1
    '  Dim db As New Grasshopper.Kernel.Types.GH_number(x(i))
    '    struct.Append(db)
    '  Next
    '  Dim struct2 As New GH_Structure(Of Grasshopper.Kernel.Types.GH_Goo)
    '  struct2.MergeStructure(struct)
    '  Dim VB As IEnumerator(Of GH_Path)
    '  VB = struct.Paths.GetEnumerator
    '  Do While VB.MoveNext
    '    Dim path As GH_Path = VB.Current
    ' struct2.ExtrudePath(path, strip)
    '  Loop
    '  If (Not VB Is Nothing) Then VB.Dispose
    'A = struct.Paths

是根据源代码的改写 只不过structure是无法输出的类型

里面的代码和这个极其类似
