    Example
    Create a RouteEventSource via dynamic segmentation process for line events
    {
      static void CreateLineEventSource(Geodatabase geodatabase, string routeFeatureClassName = "Roads", string eventTableName = "Accidents", string routeIdFieldName = "RID", string toMeasureFieldName = "toMeasure", string fromMeasureFieldName = "fromMeasure", string offsetFieldName = "Offset")
      {
        using (FeatureClass routesFeatureClass = geodatabase.OpenDataset<FeatureClass>(routeFeatureClassName))
        using (Table eventsTable = geodatabase.OpenDataset<Table>(eventTableName))
        {
          RouteInfo routeInfo = new RouteInfo(routesFeatureClass, routeIdFieldName);
          EventInfo eventInfo = new LineEventInfo(eventsTable, routeIdFieldName, fromMeasureFieldName, toMeasureFieldName, offsetFieldName);
          RouteEventSourceOptions routeEventSourceOptions = new LineEventSourceOptions() { IsPositiveOffsetOnRight = true };
    
          using (RouteEventSource routeEventSource = new RouteEventSource(routeInfo, eventInfo, routeEventSourceOptions))
          using (RouteEventSourceDefinition routeEventSourceDefinition = routeEventSource.GetDefinition())
          {
            // Locating errors 
            IReadOnlyList<RouteEventSourceError> errors = routeEventSource.GetErrors();
    
            // Route event source fields 
            IReadOnlyList<Field> routeEventSourceFields = routeEventSourceDefinition.GetFields();
    
            // Add RouteEventSource to the ArcGIS Pro map
            FeatureLayerCreationParams layerParams = new FeatureLayerCreationParams(routeEventSource)
            {
              Name = "HighCrashAreas"
