arcobjects - Export a join table to ArcMap

I have a shapefile (Point) and a table which I join using the following code.

public ITable JoinLayer_Table(IFeatureLayer pFeatLayer, IStandaloneTable pStTable)
        {

            IDisplayTable pDispTable;
            IFeatureClass pFCLayer;
            ITable pTLayer;
            pDispTable = (IDisplayTable)pFeatLayer;
            pFCLayer = (IFeatureClass)pDispTable.DisplayTable;

            pTLayer = (ITable)pFCLayer;

            IDisplayTable pDispTable2;
            ITable pTTable;
            pDispTable2 = (IDisplayTable)pStTable;
            pTTable = pDispTable2.DisplayTable; 

            IRelationshipClass pRelClass;
            IMemoryRelationshipClassFactory pMemRelFact = new MemoryRelationshipClassFactory();
            pRelClass = pMemRelFact.Open("TabletoLayer", (IObjectClass)pTLayer, "HouseNo", (IObjectClass)pTTable, "UNIT_ID", "forward", "backward", esriRelCardinality.esriRelCardinalityOneToMany);



            IRelQueryTableFactory pRelQueryTableFact = new RelQueryTableFactory();
            ITable pRelQueryTab = (ITable)pRelQueryTableFact.Open(pRelClass, true, null, null, "", true, true);
            return pRelQueryTab;
        }

The join results is an ITable.

Now I need to make a shapefile from the Join results and add it to the TOC in ArcMap. How can I do this?

Any code example would be greatly appreciated.

Actually I wanted to join two shapefiles (a point shapefile and a polygon shapefile) and get a point shapefile for the JOIN results, but could not do that. So that's why I have a point shapefile and the corresponding dbf of the polygon shapefile to create the Join.

Any help on this also would be greatly appreciated.
