WCF FaultException
WCF FaultException
提问于 2014-02-27 15:08:06
在构建WCF服务时，如果我没有在服务中包含WCF --我的FaultException契约，我可以在客户机上创建一个WCF服务引用，其中包含在Reference.cs文件中的所有成员。
如果我包括，我的FaultException合同，有两件事会发生。
- 在WCF测试客户端中，在合同名称(CreateFaultMessage)旁边有一个红色的"X"
- 当我创建WCF服务引用时，并不是所有成员都包含在Reference.cs文件中。
我希望有人能告诉我我做的不对，因为我不是FaultException的专家。
下面是接口中我的合同的代码声明。
[OperationContract]
[FaultContractAttribute(typeof(LogEventArgs), ProtectionLevel = ProtectionLevel.None)]
Exception CreateFaultMessage(Exception ex, string method);下面是实现接口的类中的方法。注意到对PostTransmissionRecord方法.的catch块中的CreateFaultMessage方法的调用。
public bool PostTransmissionRecord(TransmissionRecord transmissionRecord)
{
bool blnUpdated = false;
try
{
blnUpdated = TransmissionRecordGateway.InsertData(transmissionRecord);
LogMessage.WriteEventLog("Transmission records updated successfully", "Ryder.ShopProcessService.SOA", 3, null);
return blnUpdated;
}
catch (Exception ex)
{
LogMessage.WriteEventLog("Class: ShopProcessService" + CrLf + "Method: PostTransmissionRecord" + CrLf + "Error: " + ex.Message + CrLf + "InnerException: " + ex.InnerException + CrLf + "Source: " + ex.Source + CrLf + "StackTrace: " + ex.StackTrace, "Ryder.ShopProcessService.SOA", 1, null);
IssueRemedyTicket("Class: ShopProcessService" + CrLf + "Method: PostTransmissionRecord" + CrLf + "Error: " + ex.Message + CrLf + "InnerException: " + ex.InnerException + CrLf + "Source: " + ex.Source + CrLf + "StackTrace: " + ex.StackTrace);
CreateFaultMessage(ex, "UpdateSearchInventory");
return blnUpdated;
}
}
public Exception CreateFaultMessage(Exception ex, string method)
{
LogEventArgs detail = new LogEventArgs();
detail.ApplicationID = "ShopProcessService";
detail.ExceptionMessage = ex.Message;
detail.LogEventType = LogEventTypeEnum.Error;
detail.Method = method;
detail.Source = ex.Source;
detail.StackTrace = ex.StackTrace;
if (ex.InnerException != null)
detail.InnerExceptionMessage = ex.InnerException.ToString();
else
detail.InnerExceptionMessage = null;
throw new FaultException<LogEventArgs>(detail);
}更新代码
DataContract类
namespace Ryder.Enterprise.DataTransferObjects
{
[Serializable, DataContract(Name = "LogEventArgs", Namespace = "http://www.Ryder.com/SOA/DataContracts/2014/02/17")]
public class LogEventArgs
{
private string applicationID;
private string method;
private LogEventTypeEnum logEventType;
private string exceptionMessage;
private string innerExceptionMessage;
private string stackTrace;
private string source;
[DataMember(Name = "ApplicationID")]
public string ApplicationID
{
get
{
return applicationID;
}
set
{
applicationID = value;
}
}

.服务方法投掷故障
public bool UpdateSpotCheckInventory(SpotCheck transferObject)
{
bool blnUpdated = false;
try
{
blnUpdated = SpotCheckCollectionGateway.UpdateData(transferObject);
LogMessage.WriteEventLog("SpotCheck records updated successfully", "Ryder.ShopProcessService.SOA", 3, null);
return blnUpdated;
}
catch (Exception ex)
{
//throw fault exception here on service
return blnUpdated;
}
}客户端代码捕获FAULTEXCEPTION
catch (FaultException<LogEventArgs> ex)
{ ex.Detail.ApplicationID = "ShopProcessService";
ex.Detail.LogEventType = LogEventTypeEnum.Error;
serviceClient.Abort();

为了简化从服务中抛出FaultException并在客户端捕获和处理它的方法，请遵循以下代码：
服务：
public bool UpdateSpotCheckInventory(SpotCheck transferObject)
{
bool blnUpdated = false;
try
{
blnUpdated = SpotCheckCollectionGateway.UpdateData(transferObject);
LogMessage.WriteEventLog("SpotCheck records updated successfully", "Ryder.ShopProcessService.SOA", 3, null);
return blnUpdated;
}
catch (Exception ex)
{
//throw fault exception here on service
throw new FaultException("A fatal exception occurred while processing your request", new FaultCode("1000"))
}
}客户端：
catch (FaultException ex)
{
ex.Detail.ApplicationID = "ShopProcessService";
ex.Detail.LogEventType = LogEventTypeEnum.Error;
serviceClient.Abort();
// You can also access the custom message and error code sent from the service...
String customErrorCode = ex.Code.Name;
String customErrorMessage = ex.Reason;
}我相信这会解决你的问题。:-)

请尝试将CustomFault(本例中的MathFault)定义为数据契约而不是操作契约，如下所示：
[DataContract]
public class MathFault
{
//...
}在客户端：
static void Main(string[] args)
{
ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
try
{
int value1 = 22;
int value2 = 0;
int result = client.Divide(value1, value2);
Console.WriteLine("Divide({0},{1}) = {2}", value1, value2, result);
client.Close();
}
catch (FaultException<MathFault> e)
{
Console.WriteLine("FaultException<MathFault>: Math fault while doing " + e.Detail.Operation + ". Problem: " + e.Detail.ProblemType);
client.Abort();
Console.ReadLine();
}
