Question

我正在使用MVC 4创建一个游戏。有一个犯罪功能，我无法解决它。我已经尝试了很多东西，但由于我是MVC4的新手，我无法理解它。

我创建了一个单选按钮列表，每个不同的选项应该会给出不同的结果。这是到目前为止的代码：

控制器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using FiveGangs.Models;

namespace FiveGangs.Controllers.Game {
[Authorize]
public class CrimesController : Controller {
    //
    // GET: /Crimes/
    [HttpGet]
    public ActionResult Index() {
        return View();
    }
    //
    // POST: /Crimes/
    [HttpPost]
    public ActionResult Index(LocalCrimeModel.Crime crimeType) {
        //1 is de beste crime, 10 de slechste
        ViewBag.Message = "You commited the crime!";
        var db = new FGEntities();

        var g = db.UserGangster.FirstOrDefault(p => p.UserProfile.UserName == User.Identity.Name);


        g.GansterStatistic.CrimesSuccess++;
          g.Experience += 1000;
        g.Cash += 100;
        db.SaveChanges();

        return View();
    }
}
}

型号：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace FiveGangs.Models
{
public class LocalCrimeModel
{
    public enum Crime
    {
        Crime01 = 1,
        Crime02 = 2,
        Crime03 = 3,
        Crime04 = 4,
        Crime05 = 5,
        Crime06 = 6,
        Crime07 = 7,
        Crime08 = 8,
        Crime09 = 9,
        Crime10 = 10,
    }

    public Crime SelectedCrime { get; set; }
}
}

查看：

@using FiveGangs.Models
@model FiveGangs.Models.LocalCrimeModel

<!DOCTYPE html>

<html>
<head>
<title>Crimes</title>
</head>
<body>
<div>
    <h2>Crimes</h2>
    @if (ViewBag.Message != null) {
        <p class="warning">@ViewBag.Message</p>
    }

    @using (Html.BeginForm("Index")) {
        @Html.RadioButton("crimetype", LocalCrimeModel.Crime.Crime01, false)@: Rob the local bank<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime02, false)@: Rob the local casino<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime03, false)@: Rob a jewelry store<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime04, false)@: Rob the local café<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime05, false)@: Steal casino chips from the local casino<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime06, false)@: Rob the local theatre<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime07, false)@: Rob the local supermarket<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime08, false)@: Rob a laundry service<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime09, false)@: Empty a parking meter<br>
        @Html.RadioButton("crimeType", LocalCrimeModel.Crime.Crime10, false)@: Pickpocket someone<br /><br />

        <input class="btn btn-large btn-primary" type="submit" value="Commit crime!" />
    }
</div>
</body>
</html>

到目前为止，我可以成功执行犯罪，并将经验和资金添加到数据库中。我坚持改变每次犯罪的“赔付”。任何帮助表示赞赏，我一直在谷歌搜索2天没有结果。

您在寻找switch语言构造吗？

你可以写：

switch (crimeType)
{
    case LocalCrimeModel.Crime.Crime01:
        g.Experience += 1000;
        g.Cash += 100;
        break;
    case LocalCrimeModel.Crime.Crime02:
        g.Experience += 2000;
        g.Cash += 200;
        break;
    case LocalCrimeModel.Crime.Crime03:
        g.Experience += 3000;
        g.Cash += 300;
        break;
    case LocalCrimeModel.Crime.Crime04:
        g.Experience += 4000;
        g.Cash += 400;
        break;
...
    default:
        break;        
}

你不能吗？

修改：

另一方面，这种硬编码逻辑实际上不是可扩展的，犯罪不应该是enum，而应该是List<Crime>填充的表单数据库。 Crime应该是：

public class LocalCrimeModel { public class Crime { public int ID { get; set; } public string Name { get; set; } public decimal Cash { get; set; } public int Experience { get; set; } } public string Message { get; set; } public IList<Crime> Crimes { get; set; } public int SelectedCrimeID { get; set; } public Crime SelectedCrime { get { if (this.Crimes != null) { return this.Crimes.FirstOrDefault(o => o.ID == this.SelectedCrimeID); } else { return null; } } } }

CrimesController就像：

public class CrimesController : Controller { public ActionResult Index() { var model = new LocalCrimeModel(); model.Crimes = GetCrimes(); // THIS SHOULD BE A RESULT OF A DATABASE QUERY return View(model); } [HttpPost] public ActionResult Index(LocalCrimeModel model) { if (model != null) { model = new LocalCrimeModel(); // just to be sure } model.Crimes = GetCrimes(); // USE THE SAME QUERY HERE if (model != null && model.SelectedCrime != null) { var db = new FGEntities(); var g = db.UserGangster.FirstOrDefault(p => p.UserProfile.UserName == User.Identity.Name); g.GansterStatistic.CrimesSuccess++; g.Experience += model.SelectedCrime.Experience; g.Cash += model.SelectedCrime.Cash; db.SaveChanges(); model.Message = "You commited the crime!"; } else { model.Message = "Crime does not exist!"; } return View(model); } }

您的观点也可能如下：

@using FiveGangs.Models @model FiveGangs.Models.LocalCrimeModel <!DOCTYPE html> <html> <head> <title>Crimes</title> </head> <body> <div> <h2>Crimes</h2> @if (model.Message != null) { <p class="warning">@model.Message</p> } @using (Html.BeginForm()) { foreach (var crime in Model.Crimes) { <text>@Html.RadioButton("SelectedCrimeID", crime.ID, false): @crime.Name<br /></text> } <br /> <input class="btn btn-large btn-primary" type="submit" value="Commit crime!" /> } </div> </body> </html>

Answer 2

您的数据库中应该有一个Crime表，这样您就可以针对每种犯罪存储付款。

另一方面，将所有这些单选按钮更改为下拉列表是不是更好。
