我正在尝试将异常处理放入我的工作编排中，并且无法捕获异常。它一直挂起消息而不是执行我的异常块来更优雅地处理它。
有什么建议么？
以下是我收到的事件日志消息：
A message sent to adapter "WCF-Custom" on send port "InsertOracleMasterPort" with URI "oracledb://svd0odbd01:1529/ebsdev/Dedicated" is suspended.

第二条消息：
xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Orchestrations.OracleInvoice(868ee765-7874-ec30-0cc7-f81ae5ebfb2b)'.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Exception type: XlangSoapException
Source: Microsoft.XLANGs.BizTalk.Engine
Target Site: Void VerifyTransport(Microsoft.XLANGs.Core.Envelope, Int32, Microsoft.XLANGs.Core.Context)
The following is a stack trace that identifies the location where the exception occured
at Microsoft.BizTalk.XLANGs.BTXEngine.BTXPortBase.VerifyTransport(Envelope env, Int32 operationId, Context ctx)
at Microsoft.XLANGs.Core.Subscription.Receive(Segment s, Context ctx, Envelope& env, Boolean topOnly)

at Orchestrations.OracleInvoice.segment2(StopConditions stopOn)
at Microsoft.XLANGs.Core.SegmentScheduler.RunASegment(Segment s, StopConditions stopCond, Exception& exp)
这是编排：
catch 块使用这些类型的错误对象：
- System.Web.Services.Protocols.SoapException
- Microsoft.XLANGs.Core.XlangSoapException
- Microsoft.XLANGs.BaseTypes.XLANGsException
- 一般例外
- 系统异常
我认为异常处理会冒泡并被 system.exception 或一般处理程序捕获，但这并没有发生。
