通过C＃Com互操作性访问AutoCad动态块'块属性表'

Question

我正在使用AutoCAD 2017 Professional与ObjectARX_2017_Win_64。我试图查询&使用COM Interoperability修改动态块的“块属性表”属性，但没有成功。该表包含名称为Columns和包含数据的多行。数据的类型是String和Integer。 任何帮助将受到欢迎在“做东西”部分。

using Autodesk.AutoCAD.Interop; 
    using Autodesk.AutoCAD.Interop.Common; 
    using System.Runtime.InteropServices; 
    . 
    . 
    . 
    public void DrawLayout(boards board, FormAutocad frmAutoCad) 
    { 
     double[] insertpoint = new double[] { 0, IP_CONNECTOR_Y, 0 }; 
     if (AcadLinkStart(frmAutoCad)) 
     { 
      destdwg = acadApp.ActiveDocument; 
      // Get all the standard blocks from BLOCK_REF and place in destination drawing 
      CopyStandardBlocksToDrawing(); 
      AcadBlockReference o = destdwg.ModelSpace.InsertBlock(insertpoint, "041_CHASSIS", 1.0, 1.0, 1.0, 0.0); // Ensure blocks are loaded in CopyStandardBlocksToDrawing 

      Object[] attribs = o.GetAttributes() as object[]; 
      Object[] props = o.GetDynamicBlockProperties() as object[]; 
      foreach (var prop in props.OfType<AcadDynamicBlockReferenceProperty>()) 
      { 
      if (prop.PropertyName == "My_Table") 
      { 
       // Do Stuff 
      } 
     } 
    }

据我所知，你只能得到或设置属性Value，它对应于表中的行索引。

Object[] props = o.GetDynamicBlockProperties(); 
    foreach (var prop in props.OfType<AcadDynamicBlockReferenceProperty>()) 
    { 
     if (prop.PropertyName == "My_Table") 
     { 
      if (prop.Value != 0) 
       prop.Value = (short)0; // <- reset to the first row 
     } 
    }
