How to interrupt a Gurobi model optimization in c#?

Question

I've seen one can set a time limit, node limit, etc. to stop a Gurobi model optmimization but those are parameters you can only set before running the optimization.

I want to know how to interrupt programatically a optimization without stopping the program calling the model (I'm programming in c#) because I want to try using the suboptimal variable values.

If it's of any use I'm running the model in separate threads than the program GUI.

You can call Abort from a callback. See examples/c#/callback_cs.cs for an example.
