问题描述

I am trying to find out a way to handle unhandled exceptions at server side. I want control over exception handling at Domain Service level so that when any operation is called then I can log the exception and wrap it in some beautiful words to send it to the client. I found many ways for WCF and classic web services but nothing for RIA services. Please provide your suggestions.

推荐答案

您需要重写 DomainService.OnError 方法，在此<一个描述href="http://weblogs.asp.net/fredriknormen/archive/2009/12/08/wcf-ria-services-exception-handling.aspx">WCF RIA服务异常处理博客条目。我在一个基地的DomainService类在我的应用做到了这一点，而不是在每一个人的DomainService类，如下图所示。在 errorInfo.Error 属性没有二传手，所以我不认为你可以用自己的替换异常对象，但＆LT;的System.Web＆GT;＆LT;的customErrors模式=开/＆GT; 配置元素可以prevent异常的细节暴露给客户端

You need to override the DomainService.OnError method as described in this WCF RIA Services Exception Handling blog entry. I've done this in a base DomainService class rather than in each individual DomainService class in my application as shown below. The errorInfo.Error property does not have a setter so I don't think you can replace the exception object with your own, but the <system.web><customErrors mode="On" /> config element can prevent the details of the exception being exposed to the client.

[EnableClientAccess()]
public class DomainServiceBase : DomainService
{
    protected override void OnError(DomainServiceErrorInfo errorInfo)
    {
        Logger.WriteException(errorInfo.Error);
        base.OnError(errorInfo);
    }
}
