XMl in .Net

In Many cases we may need to send information across services in XML form.
Some common practice is to create a class as a model and serialize it to XML after assigning values.

Or you can use from a variety of ways in which .Net support XML data, such as Xpath, xdocument, xpathnavigator yada, yada

And then there is Linq XML. namespace System.Linq.Xml;

With Linq to XMl, we can create Xml fragments easily.
The code below shows how to create an Xml fragment from a Dictionary.
assuming resultPair is a Dictionary with values.



                    XDocument doc = new XDocument(

                    new XElement("Results",

                        from myListItem in resultPair

                        select

                            new XElement("Pair",

                            new XElement("Key", myListItem.Key),

                            new XElement("Value", myListItem.Value)

                            )

                            )

                        );

Now You’ve seen the big chunk, lets break it down!

Now to break it down we can start with the XElement
XElement myVar = new XElement("elementName", "any xml data");

myVar will have the value of “any xml data”

likewise
XElement myVar = new XElement("elementName1", new XElement("elementName2", "any xml data") );
myVar will have the value of “

any xml data

”

Unit Testing with Cache

One time I was working on a TEST-project for one of my web projects, I basically needed to test a UserControl. However, one of the function I need to test is referring to the HttpContext.Current.Cache. .

Running the test without a running web application will cause an error because HttpContext.Current.Cache is null.

So the solution was to create a sort of a dummy HttpContext.Current.

and heres how to do it.



TextWriter txtw = new StringWriter();

HttpWorkerRequest hwr= new SimpleWorkerRequest("/webapp", "c:\\inetpub\\wwwroot\\webapp\\", "default.aspx", "", txtw );

HttpContext.Current = new HttpContext(hwr);

after this HttpContext.Current.Cache is now accessible.

or even simpler



   HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));

However if you want to access HttpContext.Current.Session
then I suggest you check this Website for more options

You can also download the code files for simulating HTTP stuff. It Should be easy to find in the link above.
