arcgis pro sdk 创建要素类图层

接口一：

public Layer CreateLayer( 
   Uri dataUri,
   ILayerContainerEdit mapOrGroupLayer,
   int index,
   string layerName
)

URI参数说明：

示例：

var flyrCreatnParam = new FeatureLayerCreationParams(new Uri(@"c:dataworld.gdbcities"))
{
  Name = "World Cities",
  IsVisible = false,
  MinimumScale = 1000000,
  MaximumScale = 5000,
  DefinitionFilter = new CIMDefinitionFilter()
  {
    DefinitionExpression = "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, LayerPosition.AutoArrange);

接口二：

public FeatureLayer CreateFeatureLayer( 
   FeatureClass featureClass,
   ILayerContainerEdit mapOrGroupLayer,
   int index,
   string layerName,
   RendererDefinition rendererDefinition
)

public FeatureLayer CreateFeatureLayer( 
   Uri dataUri,
   ILayerContainerEdit mapOrGroupLayer,
   int index,
   string layerName,
   RendererDefinition rendererDefinition
)

URI说明：
