TOCControl中圖層名稱不顯示的問題

今天使用AO的TOCControl來顯示圖層名字，但是無論怎麼樣，TOCControl就是無法顯示加入的shapefile的名稱。後來才知道，原來加入shapefile時，沒有規定圖層的名字。代碼如下，希望以後遇到這個問題的朋友能夠少走彎路。

                            pMap = pHookHelper.FocusMap;

                            pWorkspaceFactory = new ShapefileWorkspaceFactoryClass();

                            pFeatureLayer = new FeatureLayerClass();

                            pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(Path.GetDirectoryName(openFileDialog.FileName), 0);

                            pFeatureLayer.FeatureClass = pFeatureWorkspace.OpenFeatureClass(Path.GetFileName(openFileDialog.FileName));

                            //這句話必須加上，否則該Layer名字将為“”，TOCContronl内的名稱也不顯示！

                            pFeatureLayer.Name = pFeatureLayer.FeatureClass.AliasName;

                            pMap.AddLayer(pFeatureLayer);

                            pMap.MapUnits = ESRI.ArcGIS.esriSystem.esriUnits.esriMeters;//必須設定機關，否則比例尺無法計算

                            ((IActiveView)pMap).Refresh();
