Using http put method in asp.net webforms

Question

Being new to ASP.NET and the fun that comes along with statelessness, I have been spending a lot of time wrapping my head around the concepts. Having said that....

I am dealing with a third party API that uses restful webservices to change/view data. First I found out how to call a webservice in asp.net, and then from viewing the APIs documentation I saw that to get data you do this:

So I wrote the following to look at a space's feature (objects in their database):

request = WebRequest.Create(ReqURL + query) as HttpWebRequest;

        if (DidAuthenticate(query))
        {
            try
            {
                //It will 404 if that space does not contain any custom attributes
                using (response = request.GetResponse() as HttpWebResponse)
                {
                    //Get the steam of the XML
                    StreamReader reader = new StreamReader(response.GetResponseStream());

                    //Put the XML in a document
                    XmlDocument doc = new XmlDocument();
                    doc.Load(reader);

                    //Grab all the space nodes
                    XmlNodeList featuresList = doc.GetElementsByTagName("r25:feature");

                    if (featuresList.Count > 0)
                    {
                        //Get all the info from the child nodes of the space node
                        foreach (XmlNode node in featuresList)
                        {
                            XmlNodeList childInfo = node.ChildNodes;

                            //The order never changes..i.e. the first index is always the id, 2nd is name, 3rd is quantity
                            Feature aFeature = new Feature(childInfo[ID].InnerText,
                                childInfo[NAME].InnerText, Int16.Parse(childInfo[QUANTITY].InnerText));

                            //Return all of the features
                            features.Add(aFeature);

                        }

                    }

                }
            }
            catch (WebException)
            {
                throw new WebException();
            }

And that worked great, I now had all the information I needed. Now, I am trying to learn how to send back information via their webservices to change information, and this is where I am struggling. I have seen that they use "PUT" to do so, so I tried to find tutorials that use http put in asp.net but I didn't find exactly what I was needing due to my ignorance on the topic or not fully understanding the results.

Here is what the API documentation says on manipulating information:

So can someone provide a quick code sample/psuedo code showing how I am to use this webservice? GET is just fine, but I am not sure where to start with PUT.

Answer 1

you can set the put in the request.Method = "PUT" and call the URL . Just try . PUT is similar to POST but rather than creating new entry its update the entry based on the Id that you send as part of the URL.
