各位大侠，小弟遇到一个问题，在C#、 2011环境下，读取到AxDbDocument下的Blocks，但是如何取得块的引用属性呢（TagString、TextString）
代码如下：
AxDbDocument dbxFile

AxDbDocument dbxFile;
                  AcadBlockReference cadRef;
                  object[] atts;
                  AcadAttributeReference att;

                  if(dbxFile != null)
                  {
                     dbxFile.Open(openDialog.FileName, null);
                     foreach(AcadBlock elem in dbxFile.Blocks)
                     {
                           {
                              //cadRef = (AcadBlockReference)elem;
                              MessageBox.Show(elem.Name + "__" + elem.Name + "__" + elem.Count.ToString());
                              for(int i = 0; i < elem.Count; i++)
                              {
                                 if (elem.Item(i).EntityName == "AcDbBlockReference")
                                 {
                                    cadRef = (AcadBlockReference)elem.Item(i);

                                    atts = (object[])cadRef.GetAttributes();
                                    foreach (AcadObject o in atts)
                                    {
                                          att = (AcadAttributeReference)o;
                                          if (att.TagString == "名称")
                                          {
                                             clsObjBlock theBlock = new clsObjBlock();
                                             theBlock.Value = att.TextString;             //显示块参照属性的tag和text的值
                                             theList.add(theBlock);                         //添加到theList
                                             break;
                                          }
                                    }
                                 }
                              }
                        }
