    Select Method (BasicFeatureLayer)
    In This Topic
    Selects features based upon the specified attribute and/or spatial criteria and combination method. For stream layer, you should call ArcGIS.Core.Data.Realtime.RealtimeFeatureClass.StopStreaming for predictable result. This method must be called on the MCT. Use QueuedTask.Run.

    Remarks

    Features are highlighted on the map and on the table view as a result of this method call.
    If there is a definition query set on the feature layer, the Select() method will automatically work on the subset of features in the feature layer that meet the definition criteria. You specify an additional query that will be applied after the feature layer's definition query by passing valid QueryFilter object for the QueryFilter parameter.
    If the feature layer has any joins, this Select() method takes that into account.
    You can use the cursor returned by Search to update features.

    To ensure maximum robustness, callers should explicitly dispose of the returned ArcGIS.Core.Data.Selection in either a using statement or a finally block.

    For stream layers, especially with high velocity real-time updates, features might get expired (removed) from the selection set.
