The relevant part to run a macro is this (where oApp is the application instance in your code):

private void RunMacro(object oApp, object[] oRunArgs)
{
    oApp.GetType().InvokeMember("Run",
        System.Reflection.BindingFlags.Default |
        System.Reflection.BindingFlags.InvokeMethod,
        null, oApp, oRunArgs);
}

In addition to amarsuperstar's answer,

I'd like to state that you program needs to be a trusted source in order to call these macros. And the Excel-File itself needs to be trusted as well.
