Polyline Calculate Length 2D

[ViniciusMachuca]

Hi,

In ArcGIS Runtime for Android exist a method called calculateLength2D in Polyline. In WPF API does not exist, what can I do?

I want to do something like this in C#:

(Android code)

Polyline polyline = new Polyline();
polyline.startPath(from.getX(), from.getY());
polyline.lineTo((float) to.getX(), (float) to.getY());        
return polyline.calculateLength2D();

Hi,

You have a couple of options.

## Option 1 ##

Client-side API methods:

ESRI.ArcGIS.Client.Geometry Namespace > Euclidian Class > Length Method : Length(Polyline) Method

ESRI.ArcGIS.Client.Geometry Namespace > Geodesic Class > Length Method : Length(Polyline) Method

## Option 2 ##

Use the GeometryService task operation LengthsAsync: http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client~ESRI.ArcGIS.Cli....

This task works with:
#1. An ArcGIS Server / ArcGIS Online Geometry server e.g. http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/Geometry/GeometryServer
#2. A LocalGeomertyService - see http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client.Local~ESRI.ArcG... for more information.


Cheers
