C# AVEVA MARINE DRAWING TREE VIEW 快速读取方法，速度真的很快

一般来讲我们使用MARAPI里面的

ElementChildFirstGet 和 ElementSiblingNextGet 函数去遍历而获得图元

  ''' <summary>
    '''  获取当前视图的全部的子视图的句柄
    ''' </summary>
    ''' <param name="draftApp">MarDrafting对象</param>
    ''' <param name="viewHandle">视图的句柄</param>
    ''' <returns>子视图句柄的list集合</returns>
    Public Shared Function ViewSubViews(draftApp As MarDrafting, viewHandle As MarElementHandle) As List(Of MarElementHandle)
        If Not draftApp.ElementIsView(viewHandle) Then
            Return Nothing
        End If
        Dim rtns As New List(Of MarElementHandle)
        Try
            Dim subvh As MarElementHandle
            Try
                subvh = draftApp.ElementChildFirstGet(viewHandle)
                rtns.Add(subvh)
            Catch ex As Exception
                Return Nothing
            End Try
 
            '读取第2个view
            Dim nextsubVh As MarElementHandle
            Try
                nextsubVh = draftApp.ElementSiblingNextGet(subvh)
                rtns.Add(nextsubVh)
            Catch ex As Exception
            End Try
            Dim errFlag As Boolean = True
            Do
                Try
                    nextsubVh = draftApp.ElementSiblingNextGet(nextsubVh)
                    rtns.Add(nextsubVh)
                Catch ex As Exception
                    errFlag = False
                End Try
            Loop While errFlag
        Catch ex As Exception
            MsgBox(ex.StackTrace)
        End Try
        Return rtns
    End Function

今天看一个不一样的

 MarDrafting mDrafting = new MarDrafting();
 if (!mDrafting.DwgCurrent()) return;
 var marW = new MarWrapper();
 try
 {
     var xmlFn = marW.PicGetData(4, -1, -1);
     if (File.Exists(xmlFn))
     {
         Interaction.MsgBox(xmlFn, MsgBoxStyle.OkOnly | MsgBoxStyle.Information);
     }
 }
 catch (Exception ex)
 {
     Interaction.MsgBox(ex.StackTrace, MsgBoxStyle.OkOnly | MsgBoxStyle.Exclamation);
 }

有没有很熟悉就是XML的树形数据结构
