IQueryFilter pQf = new QueryFilterClass();

string squery = string.Format("RowID_={0} AND ColumnID={1}", i, j);

pQf.WhereClause = squery;

IFeatureCursor pFtCursor = fengeFtCls.Search(pQf, false);

IFeature pFeature = pFtCursor.NextFeature();

int emtID = (int)pFeature.get_Value(pFeature.Fields.FindField("element_id"));
