How to display .lyr file?

hesapadam — Fri, 15 Apr 2022 08:46:24 GMT

I have a .lyr file which contains many references to raster (.ecw) files. According to the answer here https://community.esri.com/t5/arcgis-runtime-sdk-for-net-questions/loading-layer-files/m-p/622897/highlight/true#M7631 it is possible to display .lyr file by using Local Server Component. However I could not find out how. Any help is appreciated.

What layer type or data format does your .lyr file apply to?

I'm not sure if this is what you meant, but my .lyr file contains the name of a .ecw file.

ArcGIS Runtime doesn't support .lyr/.lyrx files directly but there are several options depending on what you would like to achieve:

Read the .ecw file directly and define the render with the ArcGIS Runtime API e.g. https://developers.arcgis.com/net/wpf/sample-code/stretch-renderer/
Include a layer referencing the .ecw file, and with your desired symbology defined, in your ArcGIS Pro map and share as a mobile map package then open this in ArcGIS Runtime e.g. https://developers.arcgis.com/net/wpf/sample-code/open-mobile-map-package/
Create a geoprocessing model/script in ArcGIS Pro that opens a .lyrx file and creates a layer. You would then share the model/script as a geoprocessing package and use in conjunction with ArcGIS Runtime Local Server to start a local geoprocessing service, run the geoprocessing task, and add the results to your map operational layers collection as a map image layer e.g. https://developers.arcgis.com/net/wpf/sample-code/local-server-geoprocessing/

Actually, my .lyr files contain both file geodatabase raster catalogs and feature classes. I have been using ArcGIS Engine and it is quite simple to use .lyr files. By using ArcMap, I was able to add symbology or set scale range to feature classes in the .lyr file. And it was possible to load .lyr files with ArcGIS Engine.

However, I couldn't do that in ArcGIS Runtime. Are there any ways to add feature classes with these features outside from the code in ArcGIS Runtime (symbology, scale ranges, etc.)?

We were using ArcGIS engine to display .lyr layer files in our application. Now in Runtime/Maps there is no support. IT looks like, with Local server, we have to create a gpkx of each lyr file in order to display it in our application.

Is there a way where we read the .lyr file(we have 100s of .lyr files) and display it our application using the new API? what is the supported mechanism for this feature?
