Im using FeatureExtrusionThin2 but i failed how can I use it

this is my code.

boolstatus = swDoc.Extension.SelectByID2("SketchCLine", "SKETCH", 0.873628215001, -0.02298894905307, -3.195293269994, true, 4, null, 0);

swSelMgr = (SelectionMgr)swDoc.SelectionManager;

swSelMgr.EnableContourSelection = true;
           
            boolstatus = swDoc.Extension.SelectByID2("SketchCLine", "SKETCHREGION", 0.873628215001, -0.02298894905307, -3.195293269994, true, 4, null, 0);

           swDoc.FeatureManager.FeatureExtrusionThin2(true, false, false, 0, 0, 0.5, 0, false, false, false, false, 0, 0, false, false, false, false, false, 0.5, 0, 0, 0, 0, false, 0.0, true, true, (int)swStartConditions_e.swStartSketchPlane, 0.0, false);

    swSelMgr.EnableContourSelection = false;

Thanks in advance!
