Read BrokeredMessage body multiple time

问题

I know that error message is self-explanatory, we can't read message body multiple times. here I'm using AOP (Aspect Oriented Programming) for audit log.

[AuditServiceMethod(AttributePriority = 0)]
[FunctionName("ValidateSubscriber")]
    public static async Task RunAsync([ServiceBusTrigger("validate-message", AccessRights.Manage,
        Connection = "ServiceBusConnection")]BrokeredMessage message,
        TraceWriter log,
        [Inject(typeof(ICommonUtilities))] ICommonUtilities commonUtility)
    {
        string body;
        using (var stream = message.GetBody<Stream>())
        using (var streamReader = new StreamReader(stream, Encoding.UTF8))
        {
            body = await streamReader.ReadToEndAsync();
        }
}

[AuditServiceMethod] is my aspect for audit request, response and error log. Is there any good workaround to get body multiple time in Azure function??

You need to clone BrokeredMessage and use the clone rather than the original message.
