BizTalk业务流程错误

Question

我使用BizTalk业务流程调用.NET类（方法），我收到以下错误：

xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'g2.interop.abbyy.poc.POC_Orchestration(44aa4941-bbfb-1b34-dfad-19ca74cac233)'. 
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.

貌似你试图打开或读取文件，这两者都可以没有找到或者你没有权限。
