ESRI.ArcGIS.Carto.IFeatureLayer pFeatureLayer = axMapControl1.get_Layer(cbxLayerName.SelectedIndex) as ESRI.ArcGIS.Carto.IFeatureLayer;
if (pFeatureLayer == null)
{
MessageBox.Show("选择图层不是Feature图层！");
return;
}
ESRI.ArcGIS.Geodatabase.IQueryFilter queryFilter = new ESRI.ArcGIS.Geodatabase.QueryFilterClass();
queryFilter.WhereClause = queryFiltertextBox.Text;

try
{
ESRI.ArcGIS.Geodatabase.IFeatureCursor featureCursor = pFeatureLayer.Search(queryFilter, false);

ESRI.ArcGIS.Geodatabase.IFeature pFeature;
while ((pFeature = featureCursor.NextFeature()) != null)
{
axMapControl1.FlashShape(pFeature.Shape);
}
}
catch (Exception pException)
{
MessageBox.Show(pException.Message);
}
cbxLayerName.SelectAll();
