Response from ASMX - c#

We have an old bit of code, ASMX WebService, that we have lost the source to. I am trying to replicate the behavior of this so we can take control of it once again without affecting any of the clients.
I have created a class that mimics the behavior and properties of the response, and a soap request returns as follows
<soap:Body>
<LoginResponse>
<LoginResult>
<UserId>string</UserId>
<Password>string</Password>
</LoginResult>
</LoginResponse>
Now the service I am trying to replicate returns
<soap:Body>
<LoginRS xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<UserId>string</UserId>
<Password>Password</Password>
</LoginRS>
</soap:Body>
Now LoginRS is the name of the class I have made. My question is how do I make my response look like the second response.
I am replicating this in c# ASMX and am using the following
[WebMethod(MessageName="Login")]
public LoginRS Login(string password, string userId)
Thanks for you time.

If your objective is to reverse engineer the service, and if the service dll is with you, you can use .NET Reflector (google it) to read the dll and provide you the exact source code.

Asmx Webservice Method to receive an soap xml input string

Good day.
i am hoping that someone could assist me. I am creating a web service (this is the first time i have ever created a web service). i have worked with web services/API in the past from a client side by creating soap xml messages and sent and received messages back and forth. Now i need to create my own web Service and am needing a little assistance with creating it correctly.
i initially created a simple web method as follows.
[WebMethod(Description = "Soap Request")]
public string Request(string xmlDocument)
{
//do work
}
but when i tried consuming this method i received the following error:
System.Web.HttpRequestValidationException: A potentially dangerous
Request.Form value was detected from the client
i then tried (after googling) to change the method as follows:
[WebMethod(Description = "Soap Request")]
public string Request(XmlDocument xmlDocument)
{
//do work
}
but that didnt seem to work either, when i tried to send an xml soap message to this method it came through empty. What i then did was to create the method with parameters matching the elements in my xml Soap message. the method then picked up each element and populated the parameters correctly as follows.
public void Request(string parm1, string parm2)
{
//do work
}
with the following xml
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
<soapenv:Header/>
<soapenv:Body>
<tem:Request>
<tem:Parm1>111</tem:Parm1>
<tem:Parm2>222</tem:Parm2>
</tem:Request>
</soapenv:Body>
</soapenv:Envelope>
i would like to find out, is this the correct way to handle the incoming message or is there something else i should be doing to accept the incoming xml message? i thought that i could create the method as i had initially done that it would accept the xml string passed to it and i could work with the message as i did when receiving xml message back from web services i used in the past.
please forgive me if i have duplicated a question, i could not find anything that would give me a definite answer.
i have started creating the web service in Visual Studio 2019.
any assistance or advise would be greatly appreciated.
I was having the exact same issue. So in my project I just added this to my web.config/system.web/httpRuntime:
requestValidationMode="2.0"
And It just worked!

How to consume SOAP Siebel webservices in .net

Hi I am developing web application which contains Siebel web service integration. All request/response cycle will take place through XML. It is basically SOAP service. I do not have idea on siebel and soap xml. I am trying to integrate siebel service in WebAPi2. Client have provided me request and response and created sample service to test. I am able to invoke siebel service in fidler. In my webapi2 i want to integrate service.
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rol="Some Url">

<rol:IDType>National Id</rol:IDType>
<rol:Type>Customer</rol:Type>
// other parametrs
</rol:process>
</soapenv:Body>
</soapenv:Envelope>
Below is the response

Also they have provided Public url to hit the API.
As i do not know Siebel integration in .Net and i did not find any suitable tutorial I am expecting some help from here. Any help/suggestion i get here highly appreciated. Thank you.
Although #AJPerez is correct that this is not really a Siebel issue, I would like to recommend you request for the WSDL (Web Service Definition file) from which your example message is generated. Without it you'll find it hard to use the generic .NET tutorials regarding web services.
.NET has no doubt a generator that takes a WSDL as input and generates a set of classes and functions for you to use.

Calling soap with C# script in a SSIS Script Task

Well that's a mouthful for a title. Let me start out by saying that I am not a programming per se but a DBA. I can write some MSSQL query with the best of them but my knowledge of C# is pretty limited. I have a piece of software that I need to communicate with via web services to push some data to all within the constraints of SQL Server Integration Services. I can read from the DB directly but I can not write to it. I'm querying some data, emailing that data, and I need to write back to the software for reach record we emailed through web services. The WSDL is available but like I said, zero knowledge of C#. I was able to build a SOAP envelope through SOAPUI that works perfectly and I would like to figure out a way call SOAP using a C# script in my SSIS package.
I have also tried to run this in the Web Service Task in SSIS and my WSDL file only gives me 4 methods when I should have close to a hundred. It would be easier there to sort out but I understand there are some limitations with the SSIS Web Service Task.
I have seen this thread: Client to send SOAP request and received response
Which unfortunately does not work for me when I copy and paste my SOAP and header into the code. To throw another wrench this thing, this is a protected web services which requires 3 credentials to have a token issued for passing data back and forth. A side question is can I run multiple SOAP calls (first to authenticate, then to push my data into the web service) through a C# script?
Here was my second soap call after getting the token that I was able to run:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"xmlns:v2="http://www.WSAPI.AMS360.com/v2.0">
<soapenv:Header>
<v2:WSAPIAuthToken>
<v2:Token>tokenremoved</v2:Token>
</v2:WSAPIAuthToken>
</soapenv:Header>
<soapenv:Body>
<v2:InsertActivity_Request>

XSD Namespace with different client

I have developed a web service in ASP.NET using C#. One of its web methods returns a complex type created from an xsd schema file using the xsd command.
Many client devices use this web services without a problem. WindowsMobile, PC. All are .Net applications.
Now one VB6 client needs to use this web service using SOAP Toolkit 3.0 and he has a problem probably due to the for different namespaces in the serialized xml data.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetProductionDataMachineryResponse xmlns="http://myFactory.it/">
<GetProductionDataMachineryResult xmlns="http://tempuri.org/XMLSchemaData.xsd">
<ResultRequest>Ok or No Data Found </ResultRequest>
.....
</GetProductionDataMachineryResult>
</GetProductionDataMachineryResponse>
</soap:Body>
</soap:Envelope>
If I remove the following annotations in the .cs file
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/XMLSchemaData.xsd")]
[System.Xml.Serialization.XmlRootAttribute(Namespace="http://tempuri.org/XMLSchemaData.xsd", IsNullable=false)]
the VB6 client works fine. But the other clients need to update the web reference.
There are over 80 other clients so this is not an attractive option.
Is there a way to get this to work with the new client without breaking the old ones?

Semi-custom WCF proxy returns zeros, despite valid data coming back on wire

There is a series of SOAP services which I wish to call (across a series of services), and while the end points are well defined & documented, there is no WSDL data... so I decided to build my own.
In order to do so, I built a test WCF service which matches the known interface of the service I wish to call.
I then saved the WSDL it exposed, changed the base address the WSDL references, created my proxy (with wsdl.exe), added it to a test client project, and can successfully create a proxy and make calls which causes the SOAP service to send the expected response... only this expected response is not picked up by the proxy and returned to the calling code.
When looking at the back and forth traffic... I can clearly see that the service is replying with what I want.
Any suggestions as to how I might troubleshoot this and get the proxy to pickup the data?
Given the replies are effectively identical, I'm forced to look back at the differences between what my client is sending and another sends.
A known working app sends it's XML blob starting with the following:
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
While my client immediately starts with the envelope (without the xml tag, and with one less namespace):
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
The other difference is that the message within the body is prefixed by a namespace in theirs, while mine it is not... though both define this namespace within the tag.
Ala:
<s:Body>
<u:DoSomething xmlns:u="urn:http://some.namespace.org" />
</s:Body>
VS:
<s:Body>
<DoSomething xmlns="urn:http://some.namespace.org" />
</s:Body>
This is not a namespace:
s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
It's setting the encoding style for the envelope which, even though it's not required per the SOAP spec, may be required by the specific implementation you're talking to. Do you have enough control over what you're sending from the client to get that put on there?
Other than that, the XML PI is not required and I think you're definitely on the right track looking at the body XML. This is almost always the case of some kind of namespace mismatch somewhere. Are you 100% positive the namespace URIs are identical?
The most likely problem is the VS version using a "default" XML namespace. There are soap parsers that I've worked which don't work correctly when using an un-aliased (default) namespaces. If you know using the u: alias works with the service, your proxy should also generate it even when every tag inside the s:Body element is prefixed with the alias.
