Access custom attribute on method from Castle Windsor interceptor

I am trying to access a custom attribute applied to a method within a castle interceptor, e.g.:

[MyCustomAttribute(SomeParam = "attributeValue")]
public virtual MyEntity Entity { get; set; }

using the following code:

internal class MyInterceptor : IInterceptor
{
    public void Intercept(IInvocation invocation)
    {
        if (invocation.Method.GetCustomAttributes(typeof(MyCustomAttribute), true) != null)
        {开发者_JS百科
            //Do something
        }
    }
}

The interceptor is firing OK when the method is called but this code does not return the custom attribute. How can I achieve this?

Try Attribute.GetCustomAttribute(...) static method for this. It's bizarre but these two methods return different results sometimes for some strange reason.

Try

private static Attribute getMyCustomAttribute(IInvocation invocation)
{
   var methodInfo = invocation.MethodInvocationTarget;
   if (methodInfo == null)
   {
      methodInfo = invocation.Method;
   }
   return Attribute.GetCustomAttribute(methodInfo, typeof(MyCustomAttribute), true);
}

I think I've figured it out - it is because of the difference between the property and the method. It is the get_ method that triggers the interceptor, and this is not decorated with the attribute of the parent property.
