I'm using VS2008 SP1, WCF Ria Service July 2009 CTP. I found out that MetadataType does not work in partial class mode, really don't know what I have missed out:
Work:-
public partial class Person
{
private string _Name;
[Required(AllowEmptyStrings=false, ErrorMessage="Name required entry")]
[StringLength(3)]
public string Name
{
set{_Name = value;}
get{return _Name;}
}
}
class Program
{
static void Main(string[] args)
{
Person p = new Person { Name="123432" };
List res = new List();
Validator.TryValidateObject(p,new ValidationContext(p,null,null),
res,true);
if (res.Count > 0)
{
Console.WriteLine(res[0].ErrorMessage);
Console.ReadLine();
}
}
}
Not Work
public partial class Person
{
private string _Name;
public string Name
{
set{_Name = value;}
get{return _Name;}
}
}
[MetadataType(typeof(PersonMetadata))]
public partial class Person
{
}
public partial class PersonMetadata
{
[Required(AllowEmptyStrings=false, ErrorMessage="Name required entry")]
[StringLength(3)]
public string Name;
}
class Program
{
static void Main(string[] args)
{
Person p = new Person { Name="123432" };
List res = new List();
Validator.TryValidateObject(p,new ValidationContext(p,null,null),
res,true);
if (res.Count > 0)
{
Console.WriteLine(res[0].ErrorMessage);
Console.ReadLine();
}
}
}
