          private void WriteBlock()
          {
              MxDrawSelectionSet ssGet = new MxDrawSelectionSet();
              MxDrawUtility      mxUtility = new MxDrawUtility();
             
              mxUtility.Prompt("\n 选择写块实体:");
              ssGet.Select (MCAD_McSelect.mcSelectionSetUserSelect,null,null,null);
         
         
              MxDrawResbuf aryId = new MxDrawResbuf();
              for(Int32 i = 0; i < ssGet.Count;i++)
              {
                  MxDrawEntity tmpEnt = ssGet.Item(i);
                  aryId.AddObjectId(tmpEnt.ObjectID );
              }
  
              MxDrawPoint basePoint = new MxDrawPoint();
  
              MxDrawDatabase dataBase = (MxDrawDatabase)axMxDrawX1.GetDatabase();
  
              MxDrawIdMapping maping;
  
              MxDrawDatabase newDataBase = dataBase.Wblock(aryId,basePoint,out maping);
  
              if(newDataBase != null)
              {
  
                  SaveFileDialog sfd = new SaveFileDialog();
                  sfd.Filter = "dwg 文件(*.dwg)|*.dwg";
  
                  if (sfd.ShowDialog() == DialogResult.OK)
                  {
                      newDataBase.SaveAs(sfd.FileName,0,null);
  
                      MessageBox.Show("写块文件成功");
                  }
  
              }
          }
