Question

求Arcengine 多个要素高亮显示C#代码

将多次属性查询的 QueryFilter所获得的要素 同时高亮显示
for (int i = 0; i < count; i++)
{
pQueryFilter.WhereClause += "cellID" + "='" + path[i].GridID + "'";
}
IFeatureSelection pFeatSelection= mFeatureLayer as IFeatureSelection;
pFeatSelection.SelectFeatures(pQueryFilter, esriSelectionResultEnum.esriSelectionResultNew, false);
我是这样写的，，最后一行有问题

Answer 1

IFeatureSelection ipFeatureSelection = ipFeatureLayer as IFeatureSelection;
ipFeatureSelection.SelectFeatures(ipQueryFilter1, esriSelectionResultNew,false);
ipFeatureSelection.SelectFeatures(ipQueryFilter2, esriSelectionResultAdd,false);
ipFeatureSelection.SelectFeatures(ipQueryFilter3, esriSelectionResultAdd,false);
……
ipMapControl.Refresh(esriViewGeoSelection);
