Question

在MVC中我的控制器（HomeController.cs）我有一个使用模型（ModelVariables）的httpPost actionResult方法（Battle），一切都很好，除非我尝试从不同的类（Intermediary.cs）中包含一个void方法，

我想做什么：在我的httpPost actionresult（Battle）中正确添加任何void方法并正确运行，这是我的代码：

Controller（HomeController.cs）：

[HttpGet]
    public ActionResult Index()
    {
        ModelVariables model = new ModelVariables()
        {

            CheckBoxItems = Repository.CBFetchItems(),
            CheckBoxItemsMasteries = Repository.CBMasteriesFetchItems(),
            CheckBoxItemsLevel = Repository.CBLevelFetchItems(),
            CheckBoxItemsItems = Repository.CBItemsFetchItems(),
            CheckBoxItemsFioraSLevel = Repository.CBFioraSLevelFetchItems(),
            CheckBoxItemsRunes = Repository.CBRunesFetchItems(),
            Inter = new Intermediary() //Here I instantiate other class
    };



        return View("Index", model);
    }

[HttpPost]
  public ActionResult Battle(ModelVariables model)
    {
        Inter.InstantiateRunes(model); //hmm doesent seem to work

        return View("Battle", model);
    }

其他课程（Intermediary.cs）：

public void InstantiateRunes(ModelVariables model)
    {
        var LifeStealQuintCount = model.CheckBoxItemsRunes.Where(x => x.CBIsSelectedRunes).Select(x => x.CBRunesID = "LS").ToList().Count;
        var LifeStealQuintValue = model.CheckBoxItemsRunes.Where(x => x.CBIsSelectedRunes && x.CBRunesID == "LS").Select(x => x.CBRunesValue).FirstOrDefault();
        if (model.CheckBoxItemsRunes != null && LifeStealQuintCount != 0 && LifeStealQuintValue != 0)
        {


            ViewBag.runeTest = LifeStealQuintValue * LifeStealQuintCount; //I set the values here, what's wrong?
        }
    }

查看（Battle.cshtml）：

@ViewBag.runeTest //unable to display due to void method not working

总结：我的代码在这里没有显示任何错误，但是当我运行这些值时似乎没有错误......

ViewBag是Controller类的属性，在ViewBag类中设置Intermediary值（与Controller无关）将无效

您尚未指出LifeStealQuintValue的类型，但假设其int（LifeStealQuintCount为）且乘法结果将始终为int，然后将您的方法更改为

public int? InstantiateRunes(ModelVariables model)
{
    var LifeStealQuintCount = model.CheckBoxItemsRunes.Where(x => x.CBIsSelectedRunes).Select(x => x.CBRunesID = "LS").ToList().Count;
    var LifeStealQuintValue = model.CheckBoxItemsRunes.Where(x => x.CBIsSelectedRunes && x.CBRunesID == "LS").Select(x => x.CBRunesValue).FirstOrDefault();
    if (model.CheckBoxItemsRunes != null && LifeStealQuintCount != 0 && LifeStealQuintValue != 0)
    {
        return LifeStealQuintValue * LifeStealQuintCount; //I set the values here, what's wrong?
    }
    return null;
}

然后将POST方法更改为

[HttpPost]
public ActionResult Battle(ModelVariables model)
{
    ViewBag.runeTest = Inter.InstantiateRunes(model);
    return View("Battle", model);
}

如何在httpPost方法中使用另一个类
