我有以下服务合同：
[ServiceContract(Namespace = "http://WebAdmin.Services.AdministrativeService", Name = "AdministrativeService")]
public interface IAdministrativeService
{
/// <summary>
/// Add the group based on the provided criteria
/// </summary>
/// <example>
/// <code>
/// service.AddWebGroup
/// (new User {
/// SequenceNumber = 1,
/// },
/// new Group
/// {
/// GroupName = "Example Group"
/// },
/// new Application
/// {
/// ApplicationCode = "DS"
/// }
/// );
/// </code>
/// </example>
/// <param name="webUser"><see cref="WebUser"/>The user a</param>
/// <param name="group"><see cref="Group"/></param>
/// <param name="application"><see cref="Application"/></param>
/// <returns><see cref="Group"/></returns>
[OperationContract]
[TransactionFlow(TransactionFlowOption.Mandatory)]
[FaultContract(typeof(ErrorFault))]
[PrincipalPermission(SecurityAction.Demand, Role = "WEB_ADMIN_SVC")]
Group AddWebGroup(WebUser webUser, Group group, Application application);
}
使用以下数据合同：
[DataContract]
public class WebUser
{
[DataMember]
public long? SequenceNumber { get; set; }
[DataMember]
public List<UserRole> Roles { get; set; }
}
[DataContract]
public class UserRole
{
[DataMember]
public long? RoleID { get; set; }
[DataMember]
public string Name { get; set; }
[DataMember]
public Application Application { get; set; }
[DataMember]
public Group Group { get; set; }
}
{
[DataContract]
public class Application
{
[DataMember]
public string ApplicationCode { get; set; }
[DataMember]
public string ApplicationName { get; set; }
[DataMember]
public string ContactEmailAddress { get; set; }
[DataMember]
public string DivisionCode { get; set; }
}
[DataContract]
public class Group
{
[DataMember]
public long? GroupID { get; set; }
[DataMember]
public string GroupName { get; set; }
}
通过以下实现：
[ServiceBehavior(
ConcurrencyMode = ConcurrencyMode.Single,
InstanceContextMode = InstanceContextMode.PerSession,
ReleaseServiceInstanceOnTransactionComplete = false,
TransactionIsolationLevel = System.Transactions.IsolationLevel.Serializable
)]
public class AdministrativeService : ServiceBase, IAdministrativeService
{
#region Implementation of IAdministrativeService

[OperationBehavior(TransactionAutoComplete = true, TransactionScopeRequired = true)]
public Group AddWebGroup(WebUser webUser, Group group, Application application)
{
if (webUser == null)
throw new ArgumentException("user");
if (webUser.SequenceNumber == long.MinValue)
throw new ArgumentException("user sequence number");
if (group == null || string.IsNullOrWhiteSpace(group.GroupName))
throw new ArgumentNullException("group");
if (application == null || string.IsNullOrWhiteSpace(application.ApplicationCode))
throw new ArgumentException("application");
var service = Resolve<IWebGroupService>();
var criteria = new GroupCriteriaEntity
{
ApplicationCode = application.ApplicationCode,
Group = new GroupEntity{GroupName = group.GroupName,},
User = new UserEntity{SequenceNumber = webUser.SequenceNumber,}
};
GroupEntity result = null;
try
{
result = service.InsertWebGroup(criteria);
}
catch (Exception ex)
{
ex.Data.Add("result",criteria);
ExceptionPolicy.HandleException(ex, "Service Policy");
}
var groupResult = new Group
{
GroupID = result.SequenceNumber
};
return groupResult;
}
服务模型绑定正在使用带有 TransportMessageCredential 的 wsHttpBinding ...
所有这些优秀的东西都可以在开发环境中使用。事务按预期提交和回滚。用户凭证允许和阻止用户执行代码，总而言之，每个人都很高兴。
测试环境应该是与开发环境相同的设置。但是，当代理客户端调用服务时，出现以下异常：
处理实例ID：44a7c5ae-17fc-4d14-b55e-1aa53bb156e0
发生并捕获了“System.ArgumentException”类型的异常。
2012 年 6 月 13 日 15:39:11 类型：System.ArgumentException，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089 消息：传入的参数不可序列化。参数名称：值源：mscorlib 帮助链接：ParamName：值数据：System.Collections.ListDictionaryInternal TargetSite：Void Add(System.Object, System.Object) 堆栈跟踪：在 System.Collections.ListDictionaryInternal.Add(Object key, Object value ) 在Administrative.Service.AdministrativeService.AddWebGroup(WebUser webUser, Group group, Application application) 在 SyncInvokeAddWebGroup(Object , Object[] , Object[] ) 在 System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] 输入, Object[]& 输出) 在 System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) 在 System.ServiceModel。
关于为什么这会发生在一台机器上而不是另一台机器上的任何想法？当传递的所有对象都是代理客户端中生成的对象并带有 DataContract 标记时，为什么我会收到一个错误，即我正在传递一个不可序列化的对象？
