为什么WCF服务引发异常时不会触发Application_Error? [英] Why Application_Error not be fired when a WCF service thrown exception?
问题描述
我有一个biz层，就像这样:
I have a biz layer just like this:
public SchoolInfo GetSchoolInfoByID(int id)
{
return SchoolDAO.GetSchoolInfoByID(id);
}
推荐答案
据我所知，Application_Error事件永远不会触发Web服务，甚至不支持Asmx Web服务.要为WCF Web服务实施错误处理，您可以实施 IErrorHandler 接口.
To my knowledge, the Application_Error event never fires for a web service, not even for asmx web services. To implement error handling for a WCF web service, you can implement the IErrorHandler interface.
以下是一些示例:
