EPLAN API 入门系列 提高篇(How to Add/Remove GraphicalLayer?)

Add GraphicalLayer:

 GraphicalLayer oGpl = null;
 GraphicalLayerTable layerTable = oPage.Project.LayerTable;

 if (oGpl == null)
  {
    oGpl = new GraphicalLayer();
    MultiLangString description = new MultiLangString();
    description.AddString(ISOCode.Language.L___, "Graphic.General");
    oGpl.Pen.ColorId = 1;
    oGpl.Create(layerTable, "Epl" + cnt.ToString(), description);
   }
 
   foreach (GraphicalLayer layer2 in layerTable.Layers)
   {
     if (layer2.Name == "Epl0" || layer2.Name == "Epl1")
     {
       oGpl = layer2;
       if (!oGpl.isVisible)
       {
         oGpl.isVisible = true;
       }
       oGpl.Pen.ColorId = 1;
       oGpl.Store();
     }
    }

Remove GraphicalLayer:

  GraphicalLayer layer = null;
  GraphicalLayerTable layerTable = currentProject.LayerTable;
  GraphicalLayer[] layers = layerTable.Layers;
  for (int num = 0; num < layers.Length; num++)
  {
    GraphicalLayer layer2 = layers[num];
    if (layer2.Name == "Epl0" || layer2.Name == "Epl1")
    {
       layerTable.RemoveLayer(layers[num]);
    }
  }
