我使用asp.net mvc和服务层创建了一个表单，用于验证业务逻辑，而无需使用数据注释进行模型验证

这是我在服务类中进行验证的代码

public class TutorService : ITutorService       
{
    private ModelStateDictionary modelstate;
    private ITutorRepository repository;

    public TutorService(ModelStateDictionary modelstate, ITutorRepository repository)
    {
        this.modelstate = modelstate;
        this.repository = repository;

    }

    //Validation Logic
    protected bool Validate(Tutor tutor)
    {

        if (tutor.FirstName==null)
            modelstate.AddModelError("FirstName", "First Name is required.");

        if (tutor.LastName == null)
            modelstate.AddModelError("LastName", "Last Name is required.");

        return modelstate.IsValid;
    }

    public bool CreateTutor(Tutor tutor)
    {
        if (Validate(tutor))
        {
            try
            {
                repository.CreateTutor(tutor);
                return true;
            }
            catch
            {
                return false;
            }

        }
        else
        {
            return false;
        }
    }

    public IEnumerable<Tutor> ListTutors()
    {
        return repository.ListTutors();
    }
}

public interface ITutorService
{
    bool CreateTutor(Tutor productToCreate);
    IEnumerable<Tutor> ListTutors();
}

也许有帮助

安装程序包jQuery.Validation.Unobtrusive

我认为可以使用
MetadataType
data注释为Tutor生成第二个类

基本上，EF将生成
Tutor
作为一个分部类，您可以使用数据注释在同一名称空间中创建另一个类

下面是它的样子

namespace MVCApplication
{
    [MetadataType(typeof(TutorMetaData))]//<- Just adding this class level attribute does the job for us.
    public partial class Tutor
    {
        public Tutor()
        {
            this.Examinations = new HashSet<Examination>();
        }

        public decimal TutorID { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string Address3 { get; set; }
        public string Tel1 { get; set; }
        public string Tel2 { get; set; }
        public string EMail { get; set; }
        public string Password { get; set; }
        public Nullable<bool> IsConfirmed { get; set; }

        public virtual ICollection<Examination> Examinations { get; set; }
    }

    public class TutorMetaData
    {
        public Tutor()
        {
            this.Examinations = new HashSet<Examination>();
        }

        public decimal TutorID { get; set; }
        [Required] //<-- use as many annotations as you like
        public string FirstName { get; set; }
        [Required] //<-- use as many annotations as you like
        public string LastName { get; set; }
        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string Address3 { get; set; }
        public string Tel1 { get; set; }
        public string Tel2 { get; set; }
        public string EMail { get; set; }
        public string Password { get; set; }
        public Nullable<bool> IsConfirmed { get; set; }

        public virtual ICollection<Examination> Examinations { get; set; }
    }
}

“~/Scripts/jquery.validate*”）；

您的属性数据注释在哪里，您正在使用服务进行验证。请显示
Tutor
classI不使用任何数据注释属性在模型内部进行验证。Tutor类是EF生成的普通类，它只包含FirstName、LastName和一些没有数据注释的其他属性。您可以发布视图吗？发布tutor类代码添加了Attribute tutor.FirstName[Remote（“Action”、“Controller”）]？就在问题答案的下方在某些情况下，一个属性使用多个视图并向同一注释显示多条错误消息（例如：创建视图显示一条错误消息，编辑视图向同一注释显示另一条错误消息）。我认为这种方法不是最好的。而且[MetadataType（typeof（TutorMetaData））]代码在edmx更改时也会刷新。
