Silverlight WCF RIA包括

Question

In my Silverlight Applcication using RIA Services I have to use [Include] in the metadata file and ObjectContext.Include("WhatEver") in the DomainServiceClass file.

Can someone please explain to me why either one of them by itself is not enough?

Thanks in advance!

Answer 1

Apparently the Association Attribute is missing. With [Include] use [Association] (in the two related Entities, with the same name for the first parameter).

here an example

class Toto
{


public int? Id
{
get;
set;
}

[Include]
[Association("Titi_Toto", "Id", "TotoId")]
public IList<Titi> TitiList
{
get;
set;
}

}

....

class Titi
{


public int? Id
{
get;
set;
}

public int? TotoId
{
get;
set;
}

[Include]
[Association("Titi_Toto", "TotoId", "Id", IsForeighKey=True)]
public Toto TotoRef
{
get;
set;
}

}
