要给出部分答案，可以检查ClientInfoView是否具有属性。一些对我有用的小演示。仍在尝试查找为什么我无法在ClientInfoViewMetaData单个属性中访问那些属性的原因
static void Main(string[] args)
{
TypeDescriptor.AddProviderTransparent(
new AssociatedMetadataTypeTypeDescriptionProvider(typeof(ClientInfoView), typeof(ClientInfoViewMetaData)), typeof(ClientInfoView));
ClientInfoView cv1 = new ClientInfoView() { ID = 1 };
var df = cv1.GetType().GetCustomAttributes(true);
var dfd = cv1.ID.GetType().GetCustomAttributes(typeof(DisplayNameAttribute), true);
var context = new ValidationContext(cv1, null, null);
var results = new List<ValidationResult>();
var isValid = Validator.TryValidateObject( cv1,context, results, true);
}
}
[MetadataType(typeof(ClientInfoViewMetaData))]
public partial class ClientInfoView
{
public int ID { get; set; }
public string Login { get; set; }
}
public class ClientInfoViewMetaData
{
[required]
[Category("Main Data"), DisplayName("Client ID")]
public int ID { get; set; }
[required]
[Category("Main Data"), DisplayName("Login")]
public string Login { get; set; }
}
