C# arcengine 由FeatureClass生成TIN

 IFields pFields = m_FeatureClass.Fields;
            int index = pFields.FindField(m_strHeight);
            if (index == -1) return;
            IField pField = pFields.get_Field(index);

            IGeoDataset pGeoDataset = m_FeatureClass as IGeoDataset;
            IEnvelope pEnvelope = pGeoDataset.Extent;
            pEnvelope.SpatialReference = pGeoDataset.SpatialReference;

            ITinEdit pTinEdit = new TinClass();
            pTinEdit.InitNew(pEnvelope);
            object obj =Type.Missing;
            pTinEdit.AddFromFeatureClass(m_FeatureClass, null, pField, null, esriTinSurfaceType.esriTinMassPoint, ref obj);
            pTinEdit.SaveAs(@"C:/TIN", ref obj);
            pTinEdit.StopEditing(false);
