XML -> method callcall is specified in XML? I mean where the XML is automatically translated to the method call. Where is it and how do I use it? Suppose I have the following class: public class Adder { public bool Add(int a, int b, out int result) { result = a + b; return true; } } Now I would like to invoke the method from XML that looks like this: <Adder> <Add> <a>10</a> <b>20</b> </Add> </Adder> ....and when it's done the XML will change to this: <Adder> <Add returnValue="true"> <a>10</a> <b>20</b> <result>30</result> </Add> </Adder> So, can I write a few lines of code, supplying XML and XSD and then the function is called? I assume this is done behind the scenes in SOAP and remoting somehow, right? Thanks! - Kristoffer - Hi Kristoffer,
First, your question is a little confusing. You started out talking about XML, which is a generic markup language, and can be used for a wide variety of purposes. You posted some "plain vanilla" XML code. Then you mentioned XSD, which is an XML schema-definition markup standard, and SOAP, which is used to process remote method calls via SOAP XML and HTTP. Methods are not serialized as XML in SOAP, but are called remotely by passing method information and parameter information in a SOAP request to an XML Web Service, which executes the method locally and returns the result of the method call via SOAP XML. So, what exactly are you asking? And what is the context/requirements of your problem? -- Show quoteHTH, Kevin Spencer Microsoft MVP Short Order Coder http://unclechutney.blogspot.com What You Seek Is What You Get "Kristoffer Persson" <KristofferPers***@discussions.microsoft.com> wrote in message news:A7BDC0F7-DB4B-41EE-ABBE-FB84CE296869@microsoft.com... > Q: Does functionality exist within the .NET CF 2 to invoke a method where > the > call is specified in XML?

What I'm looking for is a way to "post method calls" to e.g. a socket that would unfold the request into a real call to a real method on an object on the server. If XML is used to request methods to be called, then it's not necessary to have .NET on the client side and it would be easy to debug, since XML is humanly readable. I know I can invoke method calls dynamically through the functionality in the System.Runtime.Reflection namespace. But then I would have to write code for it. Not much, but still... so I thought that maybe .NET already has a way to unwrap XML that is formatted in a certain standardized way into a function call. The vanilla XML was just to give you an idea of what I'm looking for, i.e. I supply the name of the method and the params and .NET will call it for me. I also want it to be possible to have a non .NET client post XML method calls to the .NET server and have the result posted back to it. Remoting looks very nice, but I don't know what I would do if the client was non .NET. So sending XML to a socket sounded simple to me. Perhaps I'm asking the wrong thing and maybe there's a complete solution out there that does exactly what I want. If so, please forgive my ignorance and point me in the right direction. And it should work on .NET CF 2. - Kristoffer - Show quote "Kevin Spencer" wrote: > Hi Kristoffer, > > First, your question is a little confusing.

It is sent as an XML document via an HTTP request and response, again, not Microsoft technology. There is no need for any Microsoft software on the client to make a SOAP request and get back a SOAP response. The .Net Platform classes and tools for working with SOAP are just that: tools. They are not necessary to write a SOAP client. Just read the WWW documentation, follow the links, and you can go from there. -- Show quoteHTH, Kevin Spencer Microsoft MVP Short Order Coder http://unclechutney.blogspot.com What You Seek Is What You Get "Kristoffer Persson" <KristofferPers***@discussions.microsoft.com> wrote in message news:860DAB6C-90A2-427F-9CED-5B0AC25A6ABE@microsoft.com... > I'll try to be less confusing... > > What I'm looking for is a way to "post method calls" to e.g. a socket that > would unfold the request into a real call to a real method on an object on > the server.

If you like sockets, you can write a service that listens on one then, responds to an XML request. You'll probably want to do this over HTTP. There are several framework methods for this in System.Net and System.Web. This needs not involve SOAP or XSD unless you want it to. I've seen an implementation just like this. It works, but it hardly leverages the power of current standards. If you're willing to use SOAP, you can create a Web Service that'll take care of serializing and deserializing your objects without additional work on your part. You can build a SOAP client in any language, although you should always do thorough integration testing across environments because not everyone is always fully standards compliant. I'd avoid binary remoting. It's convenient and fast, but that's starting to run into platform-dependent code. It's possible to get Java or any other language to interoperate with .NET, but that is an exercise better left to people with existing applications or too much time on their hands. Anything you write in the 1.1 framework should work on the 2.0 framework without modification. How are you writing your clients? What do they do? Are they web-based in another tier, or GUI apps, or thin clients, or what?
