我是silverlight / ria的新手,我有一个我不明白的问题。
我的域服务类
中有以下代码[EnableClientAccess()]
[KnownType(typeof(ModeleEmailEa))]
[KnownType(typeof(ModeleSmsEa))]
public class EAEMailDomainService : DomainService
{
#region ModeleEnvoiEa CRUD
[Query()]
public IQueryable<ModeleEnvoiEa> SelectAllModeleEnvoiEa()
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
return modeleService.GetList<ModeleEnvoiEa>();
}
[Update]
public void UpdateModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Update(modele);
}
[Insert]
public void InsertModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Insert(modele);
}
[Delete]
public void DeleteModeleEnvoiEa(ModeleEnvoiEa modele)
{
ModeleEnvoiEaSrv modeleService = new ModeleEnvoiEaSrv();
modeleService.Delete(modele);
}
[Invoke]
public void Test(int valeur)
{
//Do something
}
#endregion
我的Silverlight应用程序中的代码
Context.Test(2, action =>
{
// Do something
}, null);
函数SelectAll,Update,Delete,Insert工作正常,但'Test'函数生成了以下错误:
尝试加载程序 格式不正确
任何想法?
答案 0 :(得分:1)
我发现如果我像这样编写函数调用它可以正常工作
Context.Test(2,new System.Action<InvokeOperation<Int>>(ModeleEnvoiEa_Completed),null);
}
void ModeleEnvoiEa_Completed(InvokeOperation invoke)
{
// Do something
}
但如果我使用像这样的lambda表达式,我有一个错误,为什么?
Context.Test(2, action =>
{
// This code generate an error
// an attempt was made to load a program with an incorrect format
}, null);
