随机函数在模型属性中的存储价值

Question

尝试使用C＃和MVC创建一个简单的Rock，Paper，Scissors游戏。目前，用户可以成功地将值输入textbox。我使用以下代码行返回文本框中的结果：<h3>Your Guess:</h3> @Html.DisplayFor(m => m.UsersGuess)

我的问题是将随机值存储在ComputerGuess模型属性中。我在Business类中创建了一个ComputerGuess()方法，但不知道如何分配这个随机数。任何帮助，将不胜感激！

@using RockPaperScissors.Business
@model RockPaperScissors.Models.Game

@{
    ViewBag.Title = "Games";
}

<h2>Rock, Paper, Scissors</h2>

@using (Html.BeginForm("Index", "Game"))
{
    <div class="form-group">
        <label>Enter your decision:</label>
        @Html.TextBoxFor(m => m.UsersGuess, new { @class = "form-control", required = "required" })


    </div>

    <div>
        <input class="btn btn-primary" type="submit" value="Guess" />
    </div>
}

<h3>Your Guess:</h3> @Html.DisplayFor(m => m.UsersGuess)
<h3>Computers Guess: </h3> @Html.DisplayFor(m => m.ComputersGuess)

namespace RockPaperScissors.Controllers
{
    public class GameController : Controller
    {
        // GET: Game
        public ActionResult Index(Game userInput)
        {
            return View(userInput);
        }

namespace RockPaperScissors.Models

        public string UsersGuess { get; set; }
        public int ComputersGuess { get; set; }
    }

业务层

using System;
using System.Collections.Generic;
using RockPaperScissors.Models;

namespace RockPaperScissors.Business
{
    public class ComputerLogic
    {
        public int ComputersGuess()
        {
            List<string> options = new List<string> { "Rock", "Paper", "Scissors" };

            var randomizer = new Random();
            var random = randomizer.Next(options.Count);

            var getRandomValue = new Game
            {
                ComputersGuess = random
            };

            return getRandomValue;
        }
    }
