wcf:同一个faultcontract在许多方法上

不,你需要在每一个方法上都这样做-WCF相当挑剔,并且需要对每一个方法都进行明确的设置(我相信这最终是件好事)。

可以通过创建自定义属性来完成。

实现IContractBehavior并将错误添加到validate方法的每个操作中。

void IContractBehavior.Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
{
   foreach (OperationDescription od in contractDescription.Operations)
      od.Add(yourFault);
}

这里是 a link 这详细说明了如何实现这一目标。在要使用的实际代码下面:

[AttributeUsage(AttributeTargets.Interface, AllowMultiple = false, Inherited = true)]
public class StandardFaultsAttribute : Attribute, IContractBehavior
{
    // this is a list of our standard fault detail classes.
    static Type[] Faults = new Type[]
    {
        typeof(AuthFailure),
        typeof(UnexpectedException),
        typeof(UserFriendlyError)
    };

    public void AddBindingParameters(ContractDescription contractDescription, ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
    }

    public void ApplyDispatchBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, DispatchRuntime dispatchRuntime)
    {
    }

    public void Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
    {
        foreach (OperationDescription op in contractDescription.Operations)
        {
            foreach (Type fault in Faults)
            {
                op.Faults.Add(MakeFault(fault));
            }
        }
    }

    private FaultDescription MakeFault(Type detailType)
    {
        string action = detailType.Name;
        DescriptionAttribute description = (DescriptionAttribute)                Attribute.GetCustomAttribute(detailType, typeof(DescriptionAttribute));

        if (description != null)
            action = description.Description;
        FaultDescription fd = new FaultDescription(action);
        fd.DetailType = detailType;
        fd.Name = detailType.Name;
        return fd;
    }
}
