    Hello. I use CPLEX Auto-Benders In Visual Studio(C#), my question is that how can I get the number of optimality  and feasibility cuts? 
    Thanks in advance.

    There is a GetNcuts method that takes as an argument an (integer) element of Cplex.CutType and returns the number of cuts. One of the elements is "Benders", which presumably returns the number of Benders cuts. I don't think there is a way to separate the number of optimality cuts from the number of feasibility cuts.
