Add Features through Enterprise REST API - Example C# .NET

I was looking through the documentation and I was having trouble finding a good example of how to add features through the API to my Workforce assignments. I figured I would put up a post up on how I was able to do get it to work.

Note: I use googles API to return Lat/Long from Addresses. This comes back in WKID 4326 and the hosted service is in Spatial Reference: 102100 or WKID 3857 so I had to convert these coordinates to import.

I found an error in the documentation when I was looking through this doc @ https://doc.arcgis.com/en/workforce/android-phone/help/workforce-schema.htm

SHAPE

The point location of the assignment.

An x,y coordinate pair.

This is incorrect, you need to have a geometry field instead of SHAPE.

Libraries used

Esri.ArcGISRuntime v200.3.0

Newtonsoft.Json v13.0.3

RestSharp v110.2.0

Code to Convert 4326 to 3857

//Convert EPSG:4326 WGS 84 to EPSG:3857 WGS 84 / Pseudo-Mercator private double[] ConvertTo3857(double[] coords) { double smRadius = 6378136.98; double smRange = smRadius * Math.PI * 2.0; double smLonToX = smRange / 360.0; double smRadiansOverDegrees = Math.PI / 180.0; double[] newCoords = new double[2]; newCoords[0] = coords[0]; newCoords[1] = coords[1]; newCoords[0] *= smLonToX; double y = newCoords[1]; if (y > 86.0) { newCoords[1] = smRange; } else if (y < -86.0) { newCoords[1] = -smRange; } else { y *= smRadiansOverDegrees; y = Math.Log(Math.Tan(y) + (1.0 / Math.Cos(y)), Math.E); newCoords[1] = y * smRadius; } return newCoords; }

This is the class to great the object that is then converted to JSON with Newtonsoft.Json. This will have to be bracketed with [ ] once converted to string to import.

public class Assignments { public Attributes attributes { get; set; } public AttributeGeometry geometry { get; set; } } public class Attributes { public string description { get; set; } public int priority { get; set; } public string assignmenttype { get; set; } public string workorderid { get; set; } public long duedate { get; set; } public string location { get; set; } public string dispatcherid { get; set; } public int status { get; set; } } public class AttributeGeometry { public double x { get; set; } public double y { get; set; } }

This class holds the result from importing and will give you the objectID if you need it for further in your code.

public class AddFeaturesResult { public Addresult[] addResults { get; set; } } public class Addresult { public bool success { get; set; } public string globalId { get; set; } public int objectId { get; set; } }

This is calls the portal. I pass in the Service name and the completed JSON String that will be inserted. responseObject has the response.

public async Task UpdateCSUAssignments(string service, string assignment) { string ServiceUrl = @"https://enterpriseUrl/server/rest/services/Hosted/" + service + @"/FeatureServer/0/addFeatures"; //Layer 0 // generate an ArcGISTokenCredential using input from the user (username and password) var cred = await Esri.ArcGISRuntime.Security.AuthenticationManager.Current.GenerateCredentialAsync( new Uri("https://enterpriseUrl/portal/sharing/rest/generateToken"), "name", "password") as ArcGISTokenCredential; //Build POST request var client = new RestClient(ServiceUrl); var request = new RestRequest(ServiceUrl, Method.Post); //Add Parameters request.AddParameter("token",cred.Token); request.AddParameter("f", "json"); request.AddParameter("features", assignment); request.AddParameter("rollbackOnFailure", "false"); //Execute Request var response = client.Execute(request); var responseObject = JsonConvert.DeserializeObject<AddFeaturesResult>(response.Content); return; }

//Create Assignment object to hold everything Assignments assignments = new Assignments(); //Create Attributes object Attributes attributes = new Attributes(); attributes.status = 0; attributes.assignmenttype = "{34AA8F52-B5A7-4DF9-9F77-169283027D14}"; attributes.location = "Full Address to import"; attributes.dispatcherid = "{AD2B0E54-FA3A-47AE-B639-95A766752E1D}"; attributes.description = "This is a test"; attributes.priority = 1; attributes.workorderid = "ID that you want tied to Assignment"; attributes.duedate = 1711980000000; //Date that has to be in UTC format //Create Geometry object in WKID 3857 AttributeGeometry geometry = new AttributeGeometry(); geometry.x = -10072068.9623985; geometry.y = 4640672.87246465; //assign attribute object to the assignment object assignments.attributes = attributes; //assign geometry to assignment object assignments.geometry = geometry; //convert object to JSON string var json = JsonConvert.SerializeObject(assignments); //add brackets for importation json = "[" + json + "]"; //PortalCode is the class that contains all my API calls. PortalCode portal = new PortalCode(); //call update assignments method var t = System.Threading.Tasks.Task.Run(async () => { await portal.UpdateCSUAssignments("This is your hosted service ID.", json); }); t.Wait();

I hope this helps, I am sure if you change your class objects for other feature services you can use the same code to add features to your services!

I wanted to thank you for posting this particular sample. It saved me a bunch of time!
