C# AutoCAD 도면에 선 종류로드

Question

로드하려는 도면에 레이어 선 종류를 설정할 수 있도록 활성 문서에 선 종류를로드하려고합니다. 이제 문제는 내가 그것을로드하려고 할 때, autocad는 나를 예외로 준다 : eWasOpenForRead. 그래서 나는 커맨드 라인을 통해 그것을 보내려고 노력했지만 그것은 효과가 있었지만, 지금 쓰고있는 애플리케이션은 ... 왜 이런 일이 일어 났는지 아무도 모른다.

코드 :

 private void defaultLayerFix() { 

     // Open a transaction for fixing layers that have the correct name 
     // but not the correct color or linetype. 
     using(curTrans = db.TransactionManager.StartOpenCloseTransaction()) { 

      // Open the layerTable and lineType table for read. 
      dwgLyrTbl = curTrans.GetObject(
       db.LayerTableId,OpenMode.ForRead) as LayerTable; 
      acLinTbl = curTrans.GetObject(
       db.LinetypeTableId,OpenMode.ForRead) as LinetypeTable; 

      // Check each layer against the standard layers DataSet. 
      foreach (ObjectId layID in dwgLyrTbl) { 
       LayerTableRecord curLayer = curTrans.GetObject(
        layID,OpenMode.ForRead) as LayerTableRecord; 

       var layerFound = _LayerDataTable.Rows.Find(curLayer.Name.ToUpper()); 
       if(layerFound != null){ 

        // Upgrade the layerTable and LayerRecord for write. 
        dwgLyrTbl.UpgradeOpen(); 
        curLayer.UpgradeOpen(); 


        // modify the color of the layer 
        curLayer.Color = Autodesk.AutoCAD.Colors.Color.FromColorIndex(
         Autodesk.AutoCAD.Colors.ColorMethod.ByAci, (short)layerFound[2]); 

        // I tried to put it in its own transaction in hopes that it would help.. but it didnt 
        using(Transaction tempTrans = db.TransactionManager.StartOpenCloseTransaction()){ 

         // if the layer is not loaded in the current dwg 
         if(!acLinTbl.Has((string)layerFound[3])) 
          try { 
           db.LoadLineTypeFile((string)layerFound[3], "acad.lin");

           Editor ed = acDoc.Editor; 
           ed.WriteMessage(e.Message); 
          } 

        tempTrans.Commit(); 
        } 

        // Change current layer linetype to... 
        curLayer.LinetypeObjectId = acLinTbl[(string)layerFound[3]]; 

        // Downgrade the layerTable, lineTable and the LayerRecord for read. 
        curLayer.DowngradeOpen(); 
        dwgLyrTbl.DowngradeOpen(); 

        // Remove the layer from the standards list 
        // so we do not attempt to have redundant layers. 
        for(int i = _LayerDataTable.Rows.Count-1; i >= 0; i--) { 
         System.Data.DataRow dr = _LayerDataTable.Rows[i]; 
         if (dr["NAME"] == layerFound[0]){ 
          dr.Delete(); 
          break; 
         } 
        } 
       } else { 

        // if the layer is not in within standard add it to a data set 
        // to fix manually. 
        if(curLayer.Name == "0") 
         continue; 
        var newRow = LayersToFix.NewRow(); 
        newRow["NAME"] = curLayer.Name; 
        // TODO get color name.. 
        newRow["COLOR"] = curLayer.Color.ColorName; 
        newRow["COLOR_ID"] = 0; 
        LinetypeTableRecord Ltype = (LinetypeTableRecord)curTrans.GetObject(
         curLayer.LinetypeObjectId,OpenMode.ForRead 
        ); 
        newRow["LINETYPE"] = Ltype.Name; 
        LayersToFix.Rows.Add(newRow); 
       } 
      } 
      // accept the changes made in this transaction 
      curTrans.Commit(); 
     }

귀하의 모든 OpenMode들 ForRead이다.

도면에서 무언가를 변경하려는 경우 도면을 변경하려는 부분에 ForWrite을 사용해야합니다. (정확한 단어가 맞는지는 모르겠지만 아이디어는 그 것이다.) 지금은 API와 familliar 해요 것을
