ESRI.ArcGIS.Geometry.IEnvelope envelope = point.Envelope;
envelope.Expand(searchTolerance, searchTolerance, false);

ESRI.ArcGIS.Geodatabase.IFeatureClass featureClass = geoFeatureLayer.FeatureClass;
System.String shapeFieldName = featureClass.ShapeFieldName;

// Create a new spatial filter and use the new envelope as the geometry
ESRI.ArcGIS.Geodatabase.ISpatialFilter spatialFilter = new ESRI.ArcGIS.Geodatabase.SpatialFilterClass();
spatialFilter.Geometry = envelope;
spatialFilter.SpatialRel = ESRI.ArcGIS.Geodatabase.esriSpatialRelEnum.esriSpatialRelEnvelopeIntersects;
spatialFilter.set_OutputSpatialReference(shapeFieldName, map.SpatialReference);
spatialFilter.GeometryField = shapeFieldName;

// Do the search
ESRI.ArcGIS.Geodatabase.IFeatureCursor featureCursor = featureClass.Search(spatialFilter, false);

这是AE帮助上的，还可以设置whereclause属性进行空间和属性综合查询
