Question

你能提供一个代码示例，其中包含用于创建服务层类的基本架构指南（应该由Web前端，web api等使用）吗？

您认为这是一个很好的教程吗？ http://www.asp.net/mvc/tutorials/older-versions/models-(data)/validating-with-a-service-layer-cs

我个人不喜欢那篇文章描述如何将错误从服务层传递回控制器（使用IValidationDictionary），我会让它更像是这样：

[Authorize]
public class AccountController : Controller
{
    private readonly IMembershipService membershipService;

    // service initialization is handled by IoC container
    public AccountController(IMembershipService membershipService)
    {
        this.membershipService = membershipService;
    }

    // .. some other stuff ..

    [AllowAnonymous, HttpPost]
    public ActionResult Register(RegisterModel model)
    {
        if (this.ModelSteate.IsValid)
        {
            var result = this.membershipService.CreateUser(
                model.UserName, model.Password, model.Email, isApproved: true
            );

            if (result.Success)
            {
                FormsAuthentication.SetAuthCookie(
                    model.UserName, createPersistentCookie: false
                );

                return this.RedirectToAction("Index", "Home");
            }

            result.Errors.CopyTo(this.ModelState);
        }

        return this.View();
    }
}

或者......正如mikalai所提到的，使服务抛出验证异常，在全局过滤器中捕获它们并插入模型状态。
