C#实现DXF文件读取写入

• 废话不多说直接上效果图、源码
• 
•  使用netDXF读取

• OpenFileDialog of = new OpenFileDialog();
                      of.Filter = "(*.dxf)|*.dxf|(*.*)|*.*";
                      if (of.ShowDialog() == true)
                      {
                          string FileName = of.FileName;
                          string SafeFileName = of.SafeFileName;
                          DxfDocument dxfDocument = DxfDocument.Load(FileName);
                          var Polylines2D_List = dxfDocument.Entities.Polylines2D;
                          List<PolylinesModel> list = new List<PolylinesModel>();
                          foreach (var item in Polylines2D_List)
                          {
                              for (int i = 0; i < item.Vertexes.Count; i++)
                              {
                                  PolylinesModel PolylinItem = new PolylinesModel();
                                  double PositionX = Math.Round(item.Vertexes[i].Position.X, 4);
                                  double PositionY = Math.Round(item.Vertexes[i].Position.Y, 4);
                                  PolylinItem.SafeFileName = SafeFileName;
                                  PolylinItem.Index = i.ToString();
                                  PolylinItem.PositionX = PositionX.ToString();
                                  PolylinItem.PositionY = PositionY.ToString();
                                  PolylinItem.PositionZ = "0.0000";
                                  list.Add(PolylinItem);
                              }
                          }
                          Polylines2DList = list;
  
                      }

• 使用netDXF写入

• List<Polyline2DVertex> polyline2DVertices = new List<Polyline2DVertex>();
                      foreach (var item in Polylines2DList)
                      {
                          Polyline2DVertex polyline2DVertex = new Polyline2DVertex(Convert.ToDouble(item.PositionX), Convert.ToDouble(item.PositionY));
                          polyline2DVertices.Add(polyline2DVertex);
                      }
                      Polyline2D line = new Polyline2D(polyline2DVertices);
                      DxfDocument dxf = new DxfDocument();
                      dxf.Entities.Add(line);
                      dxf.Save("test.dxf");
