Question

在我的解决方案中，我有WPF项目，以及与数据库一起使用的WCF项目。我使用AutoMapper来映射对象。

我的问题是：我可以将DataAnnotations与我的viewmodel类一起使用，并将它们映射到从WCF服务项目接收的对象吗？就像我在Asp.net MVC项目中所做的那样

我想使用DataAnnotations进行验证

像那样

 public class MContact
 {
      [Required(ErrorMessage = " Name is required.")]
      [StringLength(50, ErrorMessage = "No more than 50 characters")]
      [Display(Name = "Name")]
      public string Name { get; set; }


      [Required(ErrorMessage = "Email is required.")]
      [StringLength(50, ErrorMessage = "No more than 50 characters")]
      [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Valid email required e.g. abc@xyz.com")]
      public string Email { get; set; }


      [Display(Name = "Phone Number")]
      [Required]
      [RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$",
            ErrorMessage = "Entered phone format is not valid.")]
      public string PhoneNumber { get; set; }

      public string Address { get; set; }
      [RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$",
    ErrorMessage = "Entered phone format is not valid.")]
      public string Mobil { get; set; }

 }

这是我的xaml代码

不，你必须手动实现IDataErrorInfo接口。

来自sharing-validation-code-between-a-wpf-client-a-wcf-service-and-entity-framework-4-1-using-data-annotations：

您必须了解在WPF中，与Silverlight不同，组件（DataGrid）不会自动读取数据注释。您必须实现IDataErrorInfo接口并使用数据注释手动验证。

我可以将DataAnnotations与WPF中的Viewmodel类一起使用，例如MVC
