ArcEngine开发—使用ITable批量修改属性字段内容

	仅作自己记事本~~（草稿本）~~ 使用，若有不懂，纯属正常。

		private void Button1_Click(object sender, EventArgs e)
        { 
            IFeatureLayer riv_layer = pAxMap.get_Layer(cbo_Riv.SelectedIndex) as IFeatureLayer;
            IFeatureClass riv_class = riv_layer.FeatureClass;
            int rivN_index = riv_class.FindField("river_N");

            ITable pTable = riv_class as Table;
            ICursor pCursor = pTable.Update(null, true);
            IRow pRow;
            while((pRow = pCursor.NextRow()) != null)
            { 
                pRow.set_Value(rivN_index, 0);
                pCursor.UpdateRow(pRow);
            }
        }
