在 iis 上运行时如何以编程方式添加 IOperationBehavior ？
不在自定义 wcf 主机上。

谢谢

您可以将其附加为属性:

public class CustomInspectorAttribute : Attribute, IOperationBehavior, IParameterInspector
{
    #region IOperationBehavior Members

    public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation)
    {
        // Attribute could be used on client side
        clientOperation.ParameterInspectors.Add(this);
    }

    public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
    {
        // Attribute could be used on server side
        dispatchOperation.ParameterInspectors.Add(this);
    }

    public void Validate(OperationDescription operationDescription)
    {
    }

    #endregion




    #region IParameterInspector Members

    public void AfterCall(string operationName, object[] outputs, object returnValue, object correlationState)
    {
         // Do something with returned values from operation
    }

    public object BeforeCall(string operationName, object[] inputs)
    {
        // Do something with incoming parameters before invoking actual operation
        return null;
    }

    #endregion
}

并将属性附加到操作

[ServiceContract]
public interface ICustomServiceContract
{
    [CustomInspector]
    [OperationContract]
    void MyOperation();
}
