WCF / ASMX :: Read And Modify Soap Message (Programmatically)?

Apr 1, 2011

I have a web service running somewhere... I have added a reference of the same in my project. I had used SOAP UI to check the outgoing and incoming SOAP messages.

Now what i need is to MODIFY the SOAP message after it has been created (I wont be creating the soap message manually,) modify as in, I mean to insert some element into the header (such as public key etc) and encrypt the contents present in the body.

I have tried a lot of googling and have come to conclusion that i may have to use the SoapExtension Class.But i just dont understand how to do it.

There are method like ProcessMessage(... which require SoapMessage as input parameter. Now how to read
a generated SoapMessage is still unclear to me. I dont want to read the Soap message using tools (fiddler, soapui etc). I wish to read it programmatically.

How To Add Detail Element To SOAP Fault Response That Works For Both SOAP 1.1 And SOAP 1.2

Jul 1, 2010

ASP.Net 2.0 Web Services automatically create both SOAP 1.1 and SOAP 1.2 bindings. Our web service, however, has SOAP extensions and custom exception handling that make the assumption that only the SOAP 1.1 binding is used (for example, the SOAP extension uses the HTTP SOAPAction header to control behavior).

I am looking to correct the code that makes these assumptions and make it work with either SOAP 1.1 or SOAP 1.2 properly. I am running into a bit of a problem in the generation of elements for our SOAP faults.

Consider the following web method implementation:

[Code]....

The SOAP 1.2 response now has the wrong qualified name for the detail element. It should be <soap:Detail>, but instead is merely <detail>, same as the SOAP 1.1 response.

It seems that the ASP.Net 2.0 framework has done quite a bit to transform a SOAPException into the appropriate form for the SOAP version, but neglected to properly handle the detail element. Additionally, they don't seem to have exposed the correct SOAP 1.2 qualified name for the detail element as was done with the SoapException.DetailElementName property.

So, what is the correct way to add a detail element to a SOAP fault response that works for both SOAP 1.1 and SOAP 1.2? Do I need to detect the SOAP version myself and hard-code the SOAP 1.2 qualified name for the detail element?

C# - How To Retrieve A Collection Out Of A SOAP Message

Feb 15, 2011

I'm using a webservice for render company information based on a special company number.But i can not get data out of the response SOAP message. You can see an example of the response soap message. (I left out some company information the tags).

[Code]....

! this is the result i see on the demo client ! But this is my code in C#

nl.webservices.ws1.BusinessDossierV3PagedResult result = null;
result = myserviceBusiness.businessGetDossierV3(KVKnr, "0000", 1);

I want to do something like this (but with the results instead of paging part)

int page = result.paging.numpages;

Then I should be like this I suppose

string city = result.results.item.CorrespondenceCity;

But this is giving a fault message

So in Visual studio 2010, i can only retrieve the data in the paging part of the xml and put it into a textbox, but not from results part. Is this because the result part is some kind of Collection?

So yes, how can i put the data from the tags EstablishmentPostcode and EstablishmentCity in a textbox on my default page?

Programmatically Modify User Defined XML?

Jun 30, 2010

I received a user defined XML file and want to programmatically read and display it on a browser using ASP.net. I also want to allow users to add more tags, elements with their attributes according to the existing schema through the web interface used to display the XML. Where can I find some techniques with examples?

Example:

<?xml version="1.0" standalone="yes"?>
<bookstore>
<book ISBN="10-000000-001"
title="The Iliad and The Odyssey"
price="12.95">
<comments>
<userComment rating="4"
comment="Best translation I've read." />
<userComment rating="2"
comment="I like other versions better." />
</comments>
</book>
</bookstore>

The XML file contains a nested structure — each book can contain its property values, as well as one or more comments as separate elements. I want to allow users to view each of the property values and change them as well as add more userComment tags.

I'm a complete .NET newby and the only examples I can find seem really really complex. I just need something mega simple, but which an handle parameters being sent to the web service. Can anyone point me in the direction of a simple bit of C# which will do this with no frills or fuss?

WCF / ASMX :: Sending And Receiving SOAP Request In C#?

Mar 10, 2011

This is my first time trying to send a SOAP request in C#. When I click the Test button I should be passing a XML string to the web services and then getting a response. The lblTransactionNum label updates with "System.Net.ConnectStream" when it should be returning a transaction number within an unparsed response.

I'm not sure if the way I went about this is ideal but it is just from what I learned searching.

Here is my code

[Code]....

what I am missing? I have a desktop application that uses this web service in the same way but it is in VB.

Here is the VBscript from the desktop app if it contains some extra parsing steps that I will have to add to the C# for my web application but right now I am just trying to get the SOAP request and response wired up.

Custom SOAP Response Of ASMX Service

I'm trying to implement a custom SOAP response of the legacy web service. At the moment it has the following format:

I need to add string value like this:

WCF / ASMX :: Consuming SOAP From PHP That Returns Associative Arrays?

May 3, 2010

I've been trying off and on with no success to get VWD-2008 to (deserialize?) a usable object from a PHP SOAP service that returns a serialized associative array (key/value). Client only, BTW I do not have access to change the service itself.

I DO get a response as an XmlNode[] (sample below). I would just shrug and parse the XML manually (shudder) but since all the elements are named "item", "key", or "value", and then they nest in themselves, this will get really hairy. Especially, since there are a bunch of different functions from this same service that I'd like to use, and almost all of them return an associative array.

If I understand this right, the response doesn't deserialize the associative array The HelloWorld test in the WSDL works fine. From what I gather, the SoapFormatter won't deserialize generics. To be truthful, my understanding of processing data at this level in .Net is sketchy and tenuous at best, but I'll do whatever I have to do to get a workable result from this.

In theory, I should be able to use the XmlSerializer to deserialize to an IDictionary Hashtable or the like, but I'm at a loss as to how I would go about doing that. Do I have to intercept the IDE generated SOAP call? Do I have to hack the WSDL? I've even tried writing a custom class to dump the response into just so I can use it, but I've yet to pull it off, and I've got more than one or two of these to do. I've hit forum after forum and have not found where anyone has give a successful answer to this recurring issue.

The really irritating part is that it is only 3 lines of code in PHP to declare, call, and consume the service to get a usable object and I'm giving myself fits to do it in C#. It CAN'T be THIS hard to do it!

Basic format is the Java Hashtable here:
