Help !!서비스 호출을 두 번 호출 할 때 Silverlight에서 여러 개의 비동기 웹 요청이 충돌 함
여러 웹 서비스를 체인화하고 있으며 일단 호출하면 작동합니다. 두 번째로 나는 같은 전화를하려고 애썼다. 서비스 중 하나에 대한 eninvoke가 충돌한다 !! 나는 모든 것을 시도하고 수 많은 연구를 해본 결과 해결책을 찾지 못했고 심각한 마감 기한이 도래했습니다. 여기에 내 코드가있다.
public void RejectViolation(ViolationPage currentPage, Violation currentViolation, RejectionReason rejectionReason)
{
//Copy the properties over
CurrentViolation = currentViolation;
MyViolationPage = currentPage;
_rejectionReason = rejectionReason;
//First call
ServiceAgent.Validate(CurrentViolation,
(s, e) =>
{
//Reject the violation
Reject();
});
}
/// <summary>
/// Rejects the violation
/// </summary>
/// <returns>Nothing</returns>
private void Reject()
{
//Second call
ServiceAgent.RejectViolation(CurrentViolation,
(s, e) =>
{
MyViolationPage.RemoveCurrentViolation();
});
}
I am using the MVVM pattern so this is my view model. My Service Agent looks like this.
/// <summary>
/// Validates the reject
/// </summary>
/// <param name="violation">The violation to reject</param>
/// <param name="callback">The callback function</param>
public void Validate(Violation violation, EventHandler<ValidateRejectCompletedEventArgs> callback)
{
try
{
// Submit violation for Accept to server
_client.ValidateRejectCompleted -= callback;
_client.ValidateRejectCompleted += callback;
_client.ValidateRejectAsync(violation);
}
catch (FaultException)
{
throw;
}
catch (EndpointNotFoundException endpointNotFoundException)
{
throw new Exception(DataSourceMessages.EndpointNotFoundExceptionMessage, endpointNotFoundException);
}
catch (ProtocolException protocolException)
{
throw new Exception(DataSourceMessages.ProtocolExceptionMessage, protocolException);
}
catch (CommunicationException communicationException)
{
throw new Exception(DataSourceMessages.CommunicationExceptionMessage, communicationException);
}
}
/// <summary>
/// Process the reject of a violation by a user
/// </summary>
/// <param name="violation">
/// Violation to be rejected
/// </param>
/// <param name="callback">
/// Function callback to notify requester about result of the execution.
/// </param>
public void RejectViolation(Violation violation, EventHandler<RejectViolationCompletedEventArgs> callback)
{
try
{
// Submit violation for Accept to server
this._client.RejectViolationCompleted -= callback;
this._client.RejectViolationCompleted += callback;
this._client.RejectViolationAsync(violation);
}
catch (FaultException)
{
throw;
}
catch (EndpointNotFoundException endpointNotFoundException)
{
throw new Exception(DataSourceMessages.EndpointNotFoundExceptionMessage, endpointNotFoundException);
}
catch (ProtocolException protocolException)
{
throw new Exception(DataSourceMessages.ProtocolExceptionMessage, protocolException);
}
catch (CommunicationException communicationException)
{
throw new Exception(DataSourceMessages.CommunicationExceptionMessage, communicationException);
}
}
이 모든 작업을 수행 한 후에 정리해야 할 것이 있습니까? 처음으로 다시 호출하고 결과 세트를 반환 할 때 EndInvoke 메서드 에서 종료됩니다.
이것은 두 번째 시간을 충돌 어디 주위
어떤 도움을 크게 감상 할 수 결과를 검색하는 동안 충돌public CoE.VCS.SL.ViolationService.Violation EndRejectViolation(System.IAsyncResult result) {
object[] _args = new object[0];
CoE.VCS.SL.ViolationService.Violation _result = ((CoE.VCS.SL.ViolationService.Violation)(base.EndInvoke("RejectViolation", _args, result)));
return _result;
}
. 감사합니다
