Using a GPServer in .NET application

I have a GPServer that exports a PDF using an MXD as an input.

http://myserver/arcgis/rest/services...ToPDF/GPServer

I would like to call it from a .NET ArcGIS Server 10.2.2 SOE but can't find any code examples.

I can use an HTTP WebRequest to execute the GPServer but I wanted to see if there were any ArcObjects Geoprocessor ways to do it.

Please let me know if anyone has some exmaples to share.


Thanks,

Mele
