AE+C# intersect 分析，老是弹出错误

      public void Overlay_Intersect(string layername1, string layername2)
        {
          
                //分析图层
                ILayer pLayer = Map.get_Layer(GetLayerIndex(layername1));
                IFeatureLayer pInputFeatureLayer = pLayer as IFeatureLayer;
                ITable pInputTable = pLayer as ITable;
                IFeatureClass pInputFeatureClass = pInputFeatureLayer.FeatureClass;

                //叠加图层
                //  pLayer = Map.get_Layer(GetLayerIndex(layername2));
                ITable pOverlayTable = Map.get_Layer(GetLayerIndex(layername2)) as ITable;
                IFeatureClassName pFeatClassName = new FeatureClassNameClass();
                pFeatClassName.FeatureType = esriFeatureType.esriFTSimple;
                pFeatClassName.ShapeFieldName = "shape";
                pFeatClassName.ShapeType = pInputFeatureClass.ShapeType;

                //工作空间
                IWorkspaceName pNewWSName = new WorkspaceNameClass();
                pNewWSName.WorkspaceFactoryProgID = "esriDataSourcesFile.ShapefileWorkspaceFactory";
                pNewWSName.PathName = "E://temp";

                //数据集名称
               // IDatasetName pDatasetName = pFeatClassName.FeatureDatasetName;
                IDatasetName pDatasetName = pFeatClassName as IDatasetName;
                pDatasetName.Name = "Intersect_result";
                pDatasetName.WorkspaceName = pNewWSName;

                double _tol = 0.01;
                IBasicGeoprocessor pGBP;
                pGBP = new BasicGeoprocessorClass();

                IFeatureClass pOutputFeatClass;
                pOutputFeatClass = pGBP.Intersect(pInputTable, false, pOverlayTable, false, _tol, pFeatClassName);

                IFeatureLayer pOutputLayer = new FeatureLayer();
                pOutputLayer.FeatureClass = pOutputFeatClass;

                pOutputLayer.Name = pOutputFeatClass.AliasName;

                Map.AddLayer((ILayer)pOutputLayer, 0);


               
               

 
        }

执行到   pOutputFeatClass = pGBP.Intersect(pInputTable, false, pOverlayTable, false, _tol, pFeatClassName);

这一步时  弹出“对 COM 组件的调用返回了错误 HRESULT E_FAIL”
  求各位大侠帮帮忙 --------------------编程问答-------------------- 我也碰到这个问题，请问楼主这个问题怎么解决的？

补充：.NET技术 ,  C#
