add and delete query from N3 using dotnet rdf in C#

Question

I had changed my RDF file to N3 and I am using it in C# with dotNetRDF. I can parse and query on this N3 file. My question is how to add and delete an statement to my N3 files. It is a sample N3 statement, I need to add and delete such statement to my N3 files.

###  http://example.org/Sample#A

:A rdf:type owl:Class ;
   rdfs:subClassOF :B.

These statements make my hierarchy, so by adding or deleting a statement, these should be in the right place.

The Working with Graphs documentation covers the basics of doing this just via API calls as opposed to using full blown SPARQL Update.

Specifically you will be interested in the Assert() method of an IGraph implementation which is used to add new triples to a graph, the counterpart Retract() method removes triples from a graph.

If you are new to dotNetRDF I would suggest reading through the basic tutorial in our User Guide which starts with the Library Overview
