Question

我的解决方案中包含以下内容（包含4个项目）

基础设施（模型类）
存储库
服务（WCF）
网络（演示）

我使用服务引用向导（添加服务引用）来使用我的Web服务（演示文稿）

我在基础架构中运行以下操作来处理模型类：

基础建设

using System.Runtime.Serialization;
namespace Infrastructure
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;
using DataAnnotationsExtensions;

[Serializable]
[DataContract(IsReference = true)]
public partial class COUNTRIES
{
public COUNTRIES()
{
    this.CITIES = new HashSet<CITIES>();
    this.LGA = new HashSet<LGA>();
    this.STATES = new HashSet<STATES>();
}

[DataMember]
public int COUNTRY_ID { get; set; }

// [DataMember(Name = "Country Code")]
[DataMember]
[Required(ErrorMessage = "Country Code is required")]
[Display(Name = "Country Code")]
[StringLength(2, ErrorMessage = "The {0} must be at least {1} characters long. Plese check again!", MinimumLength = 2)]
//[Index(IsUnique = true)]
[RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]
public string COUNTRY_CODE { get; set; }

[DataMember]
[Required(ErrorMessage = "Country Name is required")]
[Display(Name = "Country Name")]
//[Index(IsUnique = true)]
//[StringLength(50, ErrorMessage = "Too long. Plese check again!")]
[StringLength(50, ErrorMessage = "The {0} must be at least {1} characters long. Plese check again!", MinimumLength = 2)]
[RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]
public string COUNTRY_NAME { get; set; }

[DataMember]
[Display(Name = "Action Status")]
public int ACTION_STATUS { get; set; }

[DataMember]
[Display(Name = "Date Created")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public Nullable<System.DateTime> CREATED_DATE { get; set; }

[DataMember]
[Display(Name = "Created By")]
public Nullable<int> CREATED_BY { get; set; }

[DataMember]
[Display(Name = "Last Update Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public Nullable<System.DateTime> LAST_UPDATE_DATE { get; set; }

[DataMember]
[Display(Name = "Last Update By")]
public Nullable<int> LAST_UPDATE_BY { get; set; }

[DataMember]
[Display(Name = "Date Deleted")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public Nullable<System.DateTime> DELETED_DATE { get; set; }

[DataMember]
[Display(Name = "Deleted By")]
public Nullable<int> DELETED_BY { get; set; }


[DataMember]
public virtual ICollection<CITIES> CITIES { internal get; set; }

[DataMember]
public virtual ICollection<LGA> LGA { internal get; set; }

[DataMember]
public virtual ICollection<STATES> STATES { internal get; set; }
 }
 }

然后，我的服务：WCF

namespace BPP.CCSP.Admin.Services.Services.Concrete
{

[ValidateDataAnnotationsBehavior]

public class CountriesService : ICountriesService
{
//public void DoWork()
//{
//}
 private readonly ICountriesManager _countriesManager;

 public CountriesService(ICountriesManager countriesManager)
 {
    _countriesManager = countriesManager;
 }

 public COUNTRIES GetCountry(Int32 countryID)
 {
    return _countriesManager.Country(countryID);
 }

public IEnumerable<COUNTRIES> GetCountries()
{
    return _countriesManager.Countries();
}

public void AddCountry(COUNTRIES countries)
{
    _countriesManager.AddCountry(countries);
}

public void RemoveCountry(int countryID)
{
    _countriesManager.Country(countryID);
}
}
}

我遇到的问题是数据注释没有实现。

这是流程： 基础设施（型号）=＆gt;存储库=＆gt;服务（WCF）=＆gt;网络（演示文稿）

请问，如何在表示层（视图）中实现数据注释和验证？

Answer 1

如果你想实现数据注释，那么你应该有模型参考你的演示文稿，一旦你将ref添加到你的表示层，那么你可以验证你的控制器内的模型，然后调用你的WCF服务。

将模型作为共享实体，将在所有存储库，服务（WCF），演示文稿中共享。

希望这会对你有所帮助
