Geoprocessing from ArcObjects. Help, what's wrong?

BrianBorg

I have a geoprocessing model that accept 3 parameters [layer as layerfile, clipfeatures as shape file and outputF as string]. This model clips the layer by the clipfeatures shape file and then exports the result. WHen running the model from arcInfo the model works fine but I need to call it from an Arcobjects webservices. The problem is that I am receiving a com exception error. Attached you will find the code, please help me, what is wrong with the code? The model is attached too

public string GeoprocessingLayerClipAndExport()
    {
        try
        {
         
            //Call Geoprocessing model
            ESRI.ArcGIS.Geoprocessor.Geoprocessor GP = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            GP.AddToolbox(@C:\Users\xyz\Desktop\LEMIS\Geoprocessing\Export.tbx);

            // Generate the array of parameters.
            IVariantArray parameters = new VarArrayClass();
            parameters.Add(@C:\temp\test.lyr);   //input layer
            parameters.Add(@C:\temp\clipexport\ClipF.shp); //shape file
            parameters.Add("SHAPE, C:\\temp\\exportshape\\"); //export
            GP.OverwriteOutput = true;
            GP.Execute("ClipandExport", parameters, null);
            return "ok";
        }
        catch (Exception ex)
        {
            return "error";
        }
    }
