Yes - just use the slightly weirdly named "pattern matching" from C#7 upwards to match on class or structure:

IObject concrete1 = new ObjectImplementation1();
IObject concrete2 = new ObjectImplementation2();

switch (concrete1)

    case ObjectImplementation1 c1: return "type 1";         
    case ObjectImplementation2 c2: return "type 2";         
}
