这似乎意味着"不".哪个是不幸的.

[AttributeUsage(AttributeTargets.Interface | AttributeTargets.Class,
 AllowMultiple = true, Inherited = true)]
public class CustomDescriptionAttribute : Attribute
{
    public string Description { get; private set; }

    public CustomDescriptionAttribute(string description)
    {
        Description = description;
    }
}

[CustomDescription("IProjectController")]
public interface IProjectController
{
    void Create(string projectName);
}

internal class ProjectController : IProjectController
{
    public void Create(string projectName)
    {
    }
}

[TestFixture]
public class CustomDescriptionAttributeTests
{
    [Test]
    public void ProjectController_ShouldHaveCustomDescriptionAttribute()
    {
        Type type = typeof(ProjectController);
        object[] attributes = type.GetCustomAttributes(
            typeof(CustomDescriptionAttribute),

在我的应用程序中,有几个模型需要Password属性(例如Registration和ChangePassword模型).该Password物业具有DataType和的属性Required.因此,为了确保可重用性的一致性,我创建了:

interface IPasswordContainer{
    [Required(ErrorMessage = "Please specify your password")]
    [DataType(DataType.Password)]
    string Password { get; set; }
} 

和

class RegistrationModel : IPasswordContainer {
    public string Password { get; set; }
}

不幸的是,属性不起作用.

然后我尝试将界面更改为类:

public class PasswordContainer {
    [Required(ErrorMessage = "Please specify your password")]
    [DataType(DataType.Password)]
    public virtual string Password { get; set; }
}

和

public class RegistrationModel : PasswordContainer {
    public override string Password { get; set; } …
