ASP.NET 网站后台管理系统的部分源码解析及功能介绍

在ASP.NET中，网站后台管理系统一般包含以下部份：用户管理、内容管理、系统设置等，这种部份的源码可能如下：

1、用户管理

用户管理部份主要负责用户的增删改查，包括管理员和普通用户。

public class UserController : Controller{    private readonly UserManager _userManager;    public UserController(UserManager userManager)    {        _userManager = userManager;    }    // GET: Admin/Users    public async Task Index()    {        return View(await _userManager.Users.ToListAsync());    }    // GET: Admin/Users/Create    public IActionResult Create()    {        return View();    }    // POST: Admin/Users/Create    [HttpPost]    [ValidateAntiForgeryToken]    public async Task Create([Bind("Id,UserName,NormalizedUserName,Email,EmailConfirmed,PasswordHash,SecurityStamp,ConcurrencyStamp,PhoneNumber,PhoneNumberConfirmed,TwoFactorEnabled,LockoutEnd,LockoutEnabled,AccessFailedCount")] ApplicationUser user)    {        if (ModelState.IsValid)        {            var result = await _userManager.CreateAsync(user, "YourPasswordHere");            if (result.Succeeded)            {                return RedirectToAction(nameof(Index));            }            AddErrors(result);        }        return View(user);    }    // GET: Admin/Users/Edit/5    public async Task Edit(string id)    {        if (id == null)        {            return NotFound();        }        var user = await _userManager.FindByIdAsync(id);        if (user == null)        {            return NotFound();        }        return View(user);    }    // POST: Admin/Users/Edit/5    [HttpPost]    [ValidateAntiForgeryToken]    public async Task Edit(string id, [Bind("Id,UserName,NormalizedUserName,Email,EmailConfirmed,PasswordHash,SecurityStamp,ConcurrencyStamp,PhoneNumber,PhoneNumberConfirmed,TwoFactorEnabled,LockoutEnd,LockoutEnabled,AccessFailedCount")] ApplicationUser user)    {        if (id != user.Id)        {            return NotFound();        }        if (ModelState.IsValid)        {            try            {                var result = await _userManager.UpdateAsync(user);                if (result.Succeeded)                {                    return RedirectToAction(nameof(Index));                }                AddErrors(result);            }            catch (DbUpdateConcurrencyException)            {                if (!await UserExists(user.Id))                {                    return NotFound();                }                else                {                    throw;                }            }            return View(user);        }        return View(user);    }    // GET: Admin/Users/Delete/5    public async Task Delete(string id)    {        if (id == null)        {            return NotFound();        }        var user = await _userManager.FindByIdAsync(id);        if (user == null)        {            return NotFound();        }        return View(user);    }    // POST: Admin/Users/Delete/5    [HttpPost, ActionName("Delete")]    [ValidateAntiForgeryToken]    public async Task DeleteConfirmed(string id)    {        var user = await _userManager.FindByIdAsync(id);        if (user != null)        {            await _userManager.DeleteAsync(user);        }        return RedirectToAction(nameof(Index));    }    private bool UserExists(string id)    {        return _userManager.Users.Any(e => e.Id == id);    }}

2、内容管理

内容管理部份主要负责文章、产品等内容的增删改查。

public class ContentController : Controller{    private readonly ContentManager _contentManager;    public ContentController(ContentManager contentManager)    {        _contentManager = contentManager;    }    // GET: Admin/Contents    public async Task Index()    {        return View(await _contentManager.Contents.ToListAsync());    }    // GET: Admin/Contents/Create    public IActionResult Create()    {        return View();    }    // POST: Admin/Contents/Create    [HttpPost]    [ValidateAntiForgeryToken]    public async Task Create([Bind("Id,Title,Content,Author,PublishDate")] Content content)    {        if (ModelState.IsValid)        {            await _contentManager.CreateAsync(content);            return RedirectToAction(nameof(Index));        }        return View(content);
