Exporting a layer as a shapefile programatically in C#.net

Hi ,

I'm trying to export a layer to a shape file programmatically in C#.
I found a VB code and translated and modified a bit as per my requirements. It fails at the last line.
pExportOp.ExportFeatureClass(pInDsName, null, pSelSet, null, pOutDatasetName, 1);

The compilation error is that it says cannot convert from IDatasetName to IfeatureClassName. Tried explicit casting but that also failed. Any help would be greatly appreciated.

Here is the code;

            IActiveView activeView = clsFunctions.pMxDocument.ActiveView;
            IMap map = activeView.FocusMap;
            ILayer pLayer;
            int intI = 0;
            for (intI = 0; intI <= map.LayerCount - 1; intI++)
            {
                pLayer = map.get_Layer(intI);
                if (pLayer.Name == cmbStreets.Text)
                {
                    pFeatLayer_Compare = (IFeatureLayer)pLayer;
                }
            }


            IFeatureClass pFc;
            IFeatureClassName pINFeatureClassName;
            IDataset pDataset;
            IDatasetName pInDsName;
            IFeatureSelection pFSel;
            ISelectionSet pSelSet;
            IFeatureClassName pFeatureClassName;
            IDatasetName pOutDatasetName;
            IWorkspaceName pWorkspaceName;
            IExportOperation pExportOp;

            pFc = pFeatLayer_Compare.FeatureClass;

            pDataset = (IDataset)pFc;

            pINFeatureClassName = (IFeatureClassName)pDataset.FullName;

            pInDsName = (IDatasetName)pINFeatureClassName;

            pFSel = (IFeatureSelection)pFeatLayer_Compare;
            pSelSet = pFSel.SelectionSet;

            //Define the output feature class name

            pFeatureClassName = new FeatureClassName();
            pOutDatasetName = (IDatasetName)pFeatureClassName;
            pOutDatasetName.Name = "TestExport";
            pWorkspaceName = new WorkspaceName();
            pWorkspaceName.PathName = "c:\temp";
            pWorkspaceName.WorkspaceFactoryProgID = "esriCore.shapefileworkspacefactory.1";
            pOutDatasetName.WorkspaceName = pWorkspaceName;
            pFeatureClassName.FeatureType = esriFeatureType.esriFTSimple;
            //pFeatureClassName.ShapeType = esriGeometryAny;
            pFeatureClassName.ShapeFieldName = "Shape";

            //Export
            pExportOp = new ExportOperation();
            pExportOp.ExportFeatureClass(pInDsName, null, pSelSet, null, pOutDatasetName, 1);
