I am developing a GP-Service with C#. The output is a feature set containing some attribute values. I want to determine the primary display field, which is contained in the output parameter (6th line, currently the empty string ""):{
"results": [{
"paramName": "result",
"dataType": "GPRecordSet",
"value": {
"displayFieldName": "",
"geometryType": "esriGeometryPoint",
"spatialReference": {
"wkid": 102100,
"latestWkid": 3857
},
"fields": [ ... ],
"features": [],
"exceededTransferLimit": false
}
}],
"messages": [ ... ]
}
This is how I built the ParameterInfo:
IGPParameterEdit3 result = new GPParameterClass();
IFeatureClass outputFeatureClass = DoneInAnotherMethod(); // open template from disk
result.DataType = new GPFeatureRecordSetLayerTypeClass();
IRecordSetInit recordset = new RecordSetClass();
recordset.SetSourceTable((ITable)outputFeatureClass, null);
IGPRecordSet recordSet = new GPRecordSetClass();
recordSet.RecordSet = (IRecordSet)recordset;
IGPRecordSet gpRecordSet = new GPFeatureRecordSetLayerClass();
gpRecordSet.RecordSet = new RecordSetClass();
gpRecordSet.RecordSet = (IRecordSet)recordset;
var featureRecordSetLayer = (IGPFeatureRecordSetLayer)gpRecordSet;
result.Value = (IGPValue)featureRecordSetLayer;
result.Name = Constants.OutputParameterName;
result.DisplayName = Constants.OutputParameterName;
result.Direction = esriGPParameterDirection.esriGPParameterDirectionOutput;
result.ParameterType = esriGPParameterType.esriGPParameterTypeDerived;
result.Enabled = true;
IGPFeatureSchema featureSchema = new GPFeatureSchemaClass();
featureSchema.GeometryType = esriGeometryType.esriGeometryPoint;
IGPFeatureClassDomain geomTypeDomain = new GPFeatureClassDomainClass();
geomTypeDomain.AddType(esriGeometryType.esriGeometryPoint);
result.Domain = (IGPDomain)geomTypeDomain;
result.Schema = (IGPSchema)featureSchema;
myParameterInfo.Add(result);
How can I set this value? I cannot find anything useful in ArcObjects. Any Idea?Best regards, Stefan
