Downloading Feature Layer Attachments via the ArcGIS webservices JSON and dotNet

[#1]

Hi everyone

I use this .Net code to extract the photos and attributes of a collector dataset with location tracking on. The attributes of the feature dataset and photos can be download to your box. The web services of the features should be shared.

To use this, one will need to change the Url and hardcoded attributes.

The video is here Dropbox - AGOLdownloadData.mp4 

One will have to configure the Url correctly. Below are assumed values

Srl#	Caption	Details
1	Assumed Url for feature service	http://somesampleserver.com/FeatureservicePath/ArcGIS/rest/services/LabOfflineGdbT3/FeatureServer/0/ query?where=1%3D1&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&resultType=none& distance=0.0&units=esriSRUnit_Meter&returnGeodetic=false&outFields=*&returnGeometry=true&multipatchOption=xyFootprint&maxAllowableOffset=&geometryPrecision=& outSR=&returnIdsOnly=false&returnCountOnly=false&returnExtentOnly=false&returnDistinctValues=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=& resultOffset=&resultRecordCount=&returnZ=false&returnM=false&quantizationParameters=&sqlFormat=none&f=pjson&token=
2	Assumed Url for download attachment	http://somesampleserver.com/FeatureservicePath/ArcGIS/rest/services/LabOfflineGdbT3/FeatureServer/0/ queryAttachments?objectIds={0}&f=pjson&token=
3	Assumed Url for location service url	http://somesampleserver.com/FeatureservicePath/ArcGIS/rest/services/LabOfflineGdbT3/FeatureServer/0/ query?where=1%3D1&objectIds=&time=&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelIntersects&resultType=none& distance=0.0&units=esriSRUnit_Meter&returnGeodetic=false&outFields=&returnGeometry=true&multipatchOption=xyFootprint&maxAllowableOffset=& geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&returnExtentOnly=false&returnDistinctValues=false&orderByFields=& groupByFieldsForStatistics=&outStatistics=&resultOffset=&resultRecordCount=&returnZ=false&returnM=false&quantizationParameters=& sqlFormat=none&f=pjson&token=

How to use the executable

1. Fill the main tab
2.

(1)	Enter your feature service url http://somesampleserver.com/FeatureservicePath/ArcGIS/rest/services/LabOfflineGdbT3/FeatureServer/0/	JSON location
(2)	Hardcoded but need to change if esri changes it	search url for the webservice
(3)	Hardcoded but need to change if esri changes it	download JSON url

Combination of  a. Json web service b. Search all attribute of webserice which can be hardcoded

3. Processing (Check video of processing)
4. Click the “extract” button.
5. Wait for the values to get populated
