increment unreachable in for loop in c# method

Question

I've got this unreachable code in this for loop

public IActionResult List(int id) {
    for (id = 0; id <= 1000; id++) {
        var fil = _repoFil.GetById(id).Result;
        var listafiliali = new List<FilialeVM>();

        foreach (var filiale in fil) {
            var filialeVM = _mapper.Map<FilialeVM>(fil);
            listafiliali.Add(filialeVM);
        }

        return View(listafiliali);
    }

    return View();
}

the increment id++ is unreachable

Answer 1

return your View AFTER your loop finished

public IActionResult List(int id) {
    var listafiliali = new List<FilialeVM>();

    for (id = 0; id <= 1000; id++) {
        var fil = _repoFil.GetById(id).Result;            
        foreach (var filiale in fil) {
            var filialeVM = _mapper.Map<FilialeVM>(fil);
            listafiliali.Add(filialeVM);
        }            
    }

    if(listafiliali.Count > 0)
       return View(listafiliali);

    return View();
}
