httpwebrequest

lets say i have a web request:

            WebRequest webRequest = WebRequest.Create(Url);
            webRequest.BeginGetResponse(this.RespCallback, webRequest);

now is there is any way to do retierve the URL in

    private void RespCallback(IAsyncResult asynchronousResult)
        { 
            // here 
        }

the idea is i want to provide a squence id in the url while doing webrequest and then reterive it on the call back and match it to know that this call back is from that request.

any idea?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
