AE，按照属性值关系选择要素

if(axMapControl2.LayerCount<=0)
{
MessageBox.Show("请加载图层后使用该功能","系统提示",MessageBoxButtons.OK,MessageBoxIcon.Warning);
}
else
{
ILayer pLayer = axMapControl2.get_Layer(0);
IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;
IFeatureSelection pFeatureSelection = (IFeatureSelection)pFeatureLayer;//要素层转为要素选择
IQueryFilter pQueryFilter = new QueryFilter();//（新建查询过滤器）
pQueryFilter.WhereClause = "TBMJ <1500";
pFeatureSelection.SelectFeatures(pQueryFilter, esriSelectionResultEnum.esriSelectionResultNew, false);
this.axMapControl2.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);
