我很新MVC。我正在使用interface
作为我的模型的属性。MVC3模型绑定与城堡
我注意到我的Data Annotation Attributes
被忽略。我也在提交表单时出错:
无法创建接口的实例。
很快我就想通了,我将不得不使用定制ModelBinder
我有很难搞清楚需要的ModelBinder
的CreateModel
方法,我有以下RegistrationModel
里面做什么:
public class RegistrationModel
{
#region Properties (8)
public string Email { get; set; }
public string FirstName { get; set; }
public Gender Gender { get; set; }
public string LastName { get; set; }
public string Password { get; set; }
public string PasswordConfirmation { get; set; }
public IPlace Place { get; set; }
public string Username { get; set; }
#endregion Properties
}
这里是IPlace
接口和实现:
public interface IPlace
{
#region Data Members (7)
string City { get; set; }
string Country { get; set; }
string ExternalId { get; set; }
Guid Id { get; set; }
string Name { get; set; }
string Neighborhood { get; set; }
string State { get; set; }
#endregion Data Members
}
public class Place : IPlace
{
#region Implementation of IPlace
public Guid Id { get; set; }
[StringLength(100, ErrorMessage = "City is too long.")]
public string City { get; set; }
[StringLength(100, ErrorMessage = "Country is too long.")]
public string Country { get; set; }
[StringLength(255, ErrorMessage = "External ID is too long.")]
public string ExternalId { get; set; }
[Required(ErrorMessage = "A name is required.")]
[StringLength(450, ErrorMessage = "Name is too long.")]
[DisplayName("Location")]
public string Name { get; set; }
[StringLength(100, ErrorMessage = "Neighborhood is too long.")]
public string Neighborhood { get; set; }
[StringLength(100, ErrorMessage = "State is too long.")]
public string State { get; set; }
#endregion
}
在这里使用界面有什么意义?摆脱它,并使用类“地方” – 2012-04-04 11:18:56
