    FeatureLayerCreationParams Constructor(Uri)
    In This Topic
    Creates a parameter object with System.Uri.
    Syntax

       Uri uri
    )
    Public Function New( _
       ByVal uri As Uri _
    )

    Parameters

    uri
    A System.Uri represents the path or url to a dataset or .lyrx or .lpkx file.
    Remarks

    Some sample paths to:

    A FeatureClass in a FileGeodatabase C:\Data\MyFileGDB.gdb\Census
    A shape file in a folder \\Machine\SharedFolder\MySpatialData.dbf
    A RasterDataset in a FileGeodatabase C:\Data\MyFileGDB.gdb\DEM
    A FeatureClass from a SDE C:\Connections\MySDEConnection.sde\Roads
    An image file in a folder \\Machine\SharedFolder\Imagery.tif
    A .lyrx or .lpkx file \\Machine\SharedFolder\Fires.lyrx
    A map service layer http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer
    A feature layer off a map or feature service http://sampleserver6.arcgisonline.com/arcgis/rest/services/NapervilleShelters/FeatureServer/0

    Example
    Create layer with create-params
    var flyrCreatnParam = new FeatureLayerCreationParams(new Uri(@"c:\data\world.gdb\cities"))
    {
      Name = "World Cities",
      IsVisible = false,
      MinimumScale = 1000000,
      MaximumScale = 5000,
      // At 2.x - DefinitionFilter = new CIMDefinitionFilter()
      //{
      //  DefinitionExpression = "Population > 100000",
      //  Name = "More than 100k"
      //},
      DefinitionQuery = new DefinitionQuery(whereClause: "Population > 100000", name: "More than 100k"),
      RendererDefinition = new SimpleRendererDefinition()
      {
        SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
          CIMColor.CreateRGBColor(255, 0, 0), 8, SimpleMarkerStyle.Hexagon).MakeSymbolReference()
      }
    };
    
    var featureLayer = LayerFactory.Instance.CreateLayer<FeatureLayer>(
      flyrCreatnParam, map);
    Create Stream Layer with URI
    //Must be on the QueuedTask
    var url = "https://geoeventsample1.esri.com:6443/arcgis/rest/services/AirportTraffics/StreamServer";
    var createParam = new FeatureLayerCreationParams(new Uri(url))
    {
      IsVisible = false //turned off by default
    };
    var streamLayer = LayerFactory.Instance.CreateLayer<StreamLayer>(createParam, map);
    
    //or use "original" create layer (will be visible by default)
    Uri uri = new Uri(url);
    streamLayer = LayerFactory.Instance.CreateLayer(uri, map) as StreamLayer;
    streamLayer.SetVisibility(false);//turn off
