环境准备

在开始之前，确保你的开发环境已经安装了.NET Framework和Visual Studio，你还需要一个数据库来存储用户信息和交易记录，这里以SQLite为例。

数据库设计

我们需要设计数据库来存储用户信息、交易记录等数据，以下是一些基本的表结构：

Users 表

- UserId (主键)

- Username

- PasswordHash

- Email

Transactions 表

- TransactionId (主键)

- UserId (外键)

- Amount

- Timestamp

- Status

数据访问层

使用Entity Framework来创建数据模型和数据库上下文。

using System;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
namespace BitcoinTradingPlatform.Models
{
    public class User
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int UserId { get; set; }
        public string Username { get; set; }
        public string PasswordHash { get; set; }
        public string Email { get; set; }
    }
    public class Transaction
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int TransactionId { get; set; }
        public int UserId { get; set; }
        public decimal Amount { get; set; }
        public DateTime Timestamp { get; set; }
        public string Status { get; set; }
    }
    public class TradingContext : DbContext
    {
        public DbSet<User> Users { get; set; }
        public DbSet<Transaction> Transactions { get; set; }
        public TradingContext() : base("name=TradingContext")
        {
        }
    }
}

业务逻辑层

我们将实现用户注册、登录、交易等业务逻辑。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using BitcoinTradingPlatform.Models;
namespace BitcoinTradingPlatform.Services
{
    public class UserService
    {
        private readonly TradingContext _context;
        public UserService(TradingContext context)
        {
            _context = context;
        }
        public User Register(string username, string password, string email)
        {
            var user = new User
            {
                Username = username,
                Email = email,
                PasswordHash = HashPassword(password)
            };
            _context.Users.Add(user);
            _context.SaveChanges();
            return user;
        }
        public User Login(string username, string password)
        {
            var user = _context.Users.FirstOrDefault(u => u.Username == username);
            if (user != null && VerifyPassword(password, user.PasswordHash))
            {
                return user;
            }
            return null;
        }
        private string HashPassword(string password)
        {
            using (SHA256 sha256 = SHA256.Create())
            {
                byte[] bytes = Encoding.UTF8.GetBytes(password);
                byte[] hash = sha256.ComputeHash(bytes);
                return Convert.ToBase64String(hash);
            }
        }
        private bool VerifyPassword(string password, string storedHash)
        {
            using (SHA256 sha256 = SHA256.Create())
            {
                byte[] bytes = Encoding.UTF8.GetBytes(password);
                byte[] hash = sha256.ComputeHash(bytes);
                return Convert.ToBase64String(hash) == storedHash;
            }
        }
    }
    public class TransactionService
    {
        private readonly TradingContext _context;
        public TransactionService(TradingContext context)
        {
            _context = context;
        }
        public void CreateTransaction(int userId, decimal amount)
        {
            var transaction = new Transaction
            {
                UserId = userId,
                Amount = amount,
                Timestamp = DateTime.UtcNow,
                Status = "Pending"
            };
            _context.Transactions.Add(transaction);
            _context.SaveChanges();
        }
    }
}

控制器层

在MVC架构中，控制器负责处理用户的请求。

using System.Web.Mvc;
using BitcoinTradingPlatform.Models;
using BitcoinTradingPlatform.Services;
namespace BitcoinTradingPlatform.Controllers
{
    public class AccountController : Controller
    {
        private readonly UserService _userService;
        private readonly TransactionService _transactionService;
        public AccountController(UserService userService, TransactionService transactionService)
        {
            _userService = userService;
            _transactionService = transactionService;
        }
        [HttpGet]
        public ActionResult Register()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Register(string username, string password, string email)
        {
            var user = _userService.Register(username, password, email);
            if (user != null)
            {
                return RedirectToAction("Login");
            }
            return View();
        }
        [HttpGet]
        public ActionResult Login()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Login(string username, string password)
        {
            var user = _userService.Login(username, password);
            if (user != null)
            {
                // 这里可以添加登录成功的逻辑，比如设置Session
                return RedirectToAction("Index");
            }
            return View();
        }
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult CreateTransaction(decimal amount)
        {
            var user = _userService.Login("username", "password"); // 这里需要从Session或其他地方获取用户信息
            if (user != null)
            {
                _transactionService.CreateTransaction(user.UserId, amount);
                return RedirectToAction("Index");
            }
            return RedirectToAction("Login");
        }
    }
}
