Constructors
Polyline() Constructor
Parameterless constructor for use as a Razor Component.
public Polyline();
Polyline(IReadOnlyList, SpatialReference, Nullable, Nullable) Constructor
Constructor for use in C# code. Use named parameters (e.g., item1: value1, item2: value2) to set properties in any order.
public Polyline(System.Collections.Generic.IReadOnlyList<dymaptic.GeoBlazor.Core.Model.MapPath> paths, dymaptic.GeoBlazor.Core.Components.SpatialReference? spatialReference=null, System.Nullable<bool> hasM=null, System.Nullable<bool> hasZ=null);
Parameters
paths System.Collections.Generic.IReadOnlyList<MapPath>
An array of paths, or line segments, that make up the polyline.
ArcGIS Maps SDK for JavaScript
spatialReference SpatialReference
The spatial reference of the geometry.
default SpatialReference.WGS84 // wkid: 4326
ArcGIS Maps SDK for JavaScript
hasM System.Nullable<System.Boolean>
Indicates if the geometry has M values.
ArcGIS Maps SDK for JavaScript
hasZ System.Nullable<System.Boolean>
Indicates if the geometry has z-values (elevation).

Methods
Polyline.AddPath(IReadOnlyCollection) Method
Adds a path, or line segment, to the polyline.
ArcGIS Maps SDK for JavaScript

Returns
Polyline.GetPoint(int, int) Method
Returns a point specified by a path and point in the path.
param pointIndex The index of a point in a path.
ArcGIS Maps SDK for JavaScript
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Core.Components.Geometries.Point?> GetPoint(int pathIndex, int pointIndex);
Parameters
pathIndex System.Int32
The index of a path in the polyline.
pointIndex System.Int32

Polyline.InsertPoint(int, int, Point) Method
Inserts a new point into a polyline.
param pointIndex The index of the inserted point in the path.
ArcGIS Maps SDK for JavaScript
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Core.Components.Geometries.Polyline?> InsertPoint(int pathIndex, int pointIndex, dymaptic.GeoBlazor.Core.Components.Geometries.Point point);
Parameters
pathIndex System.Int32
The index of the path in which to insert a point.
pointIndex System.Int32

Polyline.RemovePath(int) Method
Removes a path from the Polyline.
ArcGIS Maps SDK for JavaScript
public System.Threading.Tasks.Task<dymaptic.GeoBlazor.Core.Components.Geometries.Point[]?> RemovePath(int index);
Parameters
index System.Int32
The index of the path to remove from the polyline.
Returns
System.Threading.Tasks.Task<Point[]>
