Recreate Relationship Class using C# / .NET for ArcGIS Pro 2.9.6

DusanOstojic — Fri, 30 Jun 2023 13:35:39 GMT

I have been struggling with writing code for recreation of Relationship class in C# but I cannot swim out 😞

I need to recreate Relationship Class in FGDB using .NET in order to change following properties of the Relationship Class:

Name of the relationship class
Origin Primary Key
Origin Foreign Key

I imagine some kind or process would be:

Pickup existing relationship class definition using source and target table names (I tried with RelationshipClassDefinition)
Change above mentioned properties (this is where I couldn’t move forward with RelationshipClassDefinition)
Drop existing Relationship Class
Create new relationship class with new parameters

I see that in Pro 3.1 there is RelationshipClassDescription Class with which I could easily solve the probelm, but unfortunately I need to implement this task in Pro 2.9.6.

Thanks in advance for any suggestion.

Hi,

SchemaBuilder object has methods for relationship management but not in 2.9.

Before release 3.0 you have to use the 'Create Relationship Class' Geoprocessing Tool in order to create a relationship class. Since it's somewhat difficult to figure out the parameters to run a GP Tool you can follow the steps outlined in the slides for the 2023 Demo theater session (download) 'How to Run GP Tools from Your Add-in' here: Tech Sessions · ArcGIS/arcgis-pro-sdk Wiki (github.com)

Thanks for the info.

In this case I would rather implement Relationship class change in arcpy and wait for our upgrade to Pro 3.0.
