设置IncludeExceptionDetailInFaults为true在WCF代码 [英] Set IncludeExceptionDetailInFaults to true in code for WCF

问题描述

如何在代码中设置IncludeExceptionDetailInFaults不使用App.Config中

How do I set IncludeExceptionDetailInFaults in code without using App.Config?

推荐答案

是的，当然 - 在服务器端，您打开服务主机之前。然而这将需要您自托管的WCF服务 - 不会在IIS托管方案工作：

Yes, sure - on the server side, before you open the service host. This would however require that you self-host the WCF service - won't work in IIS hosting scenarios:

ServiceHost host = new ServiceHost(typeof(MyWCFService));

ServiceDebugBehavior debug = host.Description.Behaviors.Find<ServiceDebugBehavior>();

// if not found - add behavior with setting turned on 
if (debug == null)
{
    host.Description.Behaviors.Add(
         new ServiceDebugBehavior() { IncludeExceptionDetailInFaults = true });
}
else
{  
    // make sure setting is turned ON
    if (!debug.IncludeExceptionDetailInFaults)
    {
        debug.IncludeExceptionDetailInFaults = true;
    }
}

host.Open();

如果你需要做的在IIS托管同样的事情，你必须创建自己的定制 MyServiceHost 后裔和合适的 MyServiceHostFactory ，将实例化这样的定制服务宿主，并参考此自定义服务主机工厂在* .svc文件。

If you need to do the same thing in IIS hosting, you'll have to create your own custom MyServiceHost descendant and a suitable MyServiceHostFactory that would instantiate such a custom service host, and reference this custom service host factory in your *.svc file.
