I'm trying to create a WCF SOAP service that has a service method that accepts bare parameters in the body but I just cant make it happen. At the moment, the method name element is being created under the body. I'm trying to use ws-addressing so that the method name is part of the header and the parameters are the direct children of the body.
Here's my service implementation:
[SoapDocumentService(Use = SoapBindingUse.Literal, ParameterStyle = SoapParameterStyle.Bare)]
public class Service1 : IService1
{
[SoapDocumentMethod(Use=SoapBindingUse.Literal, ParameterStyle = SoapParameterStyle.Bare)]
public void DoWork([XmlElement(Namespace = "http://www.contoso.com",
IsNullable = true)] MyClass wrapper)
{
}
}
[XmlRoot(Namespace = "http://www.contoso.com")]
public class MyClass
{
public int Value { get; set; }
public string MyProperty { get; set; }
}
[ServiceContract]
public interface IService1
{
[OperationContract]
void DoWork(MyClass wrapper);
}
The above implementation generates the soap client below. But I'm trying to have the wrapper element as the direct child on body (trying to remove DoWork). From what I've read, decorating the svc method to use bare parameters should remove the service method name (DoWork) and use ws-addressing.
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/" xmlns:web="http://schemas.datacontract.org/2004/07/WebApplication2">
<soap:Header/>
<soap:Body>
<tem:DoWork> <!-- I want to remove this svc method name element -- >
<tem:wrapper> <!-- I want this to be under the body -->
<!--Optional:-->
<web:MyProperty>?</web:MyProperty>
<!--Optional:-->
<web:Value>?</web:Value>
</tem:wrapper>
</tem:DoWork>
</soap:Body>
</soap:Envelope>
I've followed the guide from msdn to decorate the service method. MSDN Link
I think you should drop the wrapper. in .net 2 this would work, wcf should be similar:
[WebMethod]
[SoapDocumentMethod(ParameterStyle=SoapParameterStyle.Bare)]
public String EchoString(String s, String s1)
{
return s;
}
I had to create message contracts wrapper for the MyClass and specify the message body.
[MessageContract]
public class MyWrapper
{
[MessageBodyMember]
public int Value { get; set; }
[MessageBodyMember]
public string MyProperty { get; set; }
}

I'm trying to port an existing Soap WebService to .NET5 but am having issue with overloading a Soap method parameter.
In NET4 the code looks like this
namespace SoapWebServiceeTest.Soap
{
/// <summary>
/// Summary description for WsgSPServiceOrderService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class TextWebService : System.Web.Services.WebService
{
[WebMethod]
public string Test(
[XmlElement("object1", typeof(Object1))]
[XmlElement("object2", typeof(Object2))]
[XmlElement("object3", typeof(Object3))]
object request)
{
return $"{request.GetType().Name}";
}
}
public class Object1 { public string Param1 { get; set; } }
public class Object2 { public string Param2 { get; set; } }
public class Object3 { public string Param3 { get; set; } }
}
How do I achieve this in .NET5?
I have tried following but got reflection exception: System.Reflection.AmbiguousMatchException: 'Multiple custom attributes of the same type found.'
[ServiceContract]
public interface ITestWebService
{
[OperationContract]
string Test(
[XmlElement("object1", typeof(Object1))]
[XmlElement("object2", typeof(Object2))]
[XmlElement("object3", typeof(Object3))]
object request);
}
And also tried this but VS Add Connected Services errored with "More than one message named 'ISampleService_Test_InputMessage' was specified. Each message must have a unique name."
[OperationContract]
string Test(Object1 request);
[OperationContract]
string Test(Object2 request);
Any help would be awesome
You may try this
You can make it post or get based on your need
[OperationContract]
[WebInvoke(UriTemplate = "Test1", Method = "POST"]
string Test(Object1 request);
and
[OperationContract]
[WebInvoke(UriTemplate = "Test2", Method = "POST"]
string Test(Object2 request);
This way you can achieve objective
I have created WCF service. It is working fine but our client want response in some specific form. I have shared 2 responses
My Code :
[ServiceContract]
public interface IService
{
[OperationContract]
MyClass GetMyData();
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class MyClass
{
int _id ;
string _name ;
[DataMember]
public int ID
{
get { return _id; }
set { _id = value; }
}
[DataMember]
public string Name
{
get { return _name; }
set { _name = value; }
}
}
Your "Client Expectation" is a XSD file. They are meant to validate SOAP responses, not to be one.
There are plenty of services which can validate your XML response based on your XSD.
If you client wants a XSD response, maybe you'll have to look for a tool to do that. I think this might help.
[DataContract]
Base
{
[DataMember]
public int Id {get;set;}
}
[DataContract]
A : Base
{
[DataMember]
public string Value {get;set;}
}
[ServiceContract]
interface IService
{
[OperationContract]
void SetValue (Base base);
}
is there a way to use the service like the following style:
new Service ().SetValue (new A ());
You tagged this WCF so I assume you want to use it.
You need to connect to the endpoint using the ChannelFactory and then open the channel.
This will not work:
new Service ().SetValue (new A ());
You need to do smth. like this:
using (var scf = new ChannelFactory< IService >(<Binding>,<EndpointAddress>)
{
IService proxy = scf.CreateChannel();
proxy.SetValue(new (A));
}
This will return you a proxy object that implements the IService interface. You can call the SetValue on this object.
As well as changing the way you're calling the service as indicated by #Flo, you'll also need to make a small change to prepare the Data Contract Serializer to deal with the inheritance hierarchy.
The easiest way of doing this is decorating Base with the KnownTypeAttribute. Like this,
[DataContract]
[KnownType(typeof(A))]
Base
{
[DataMember]
public int Id {get;set;}
}
[DataContract]
A : Base
{
[DataMember]
public string Value {get;set;}
}
I am aware that there is a similar question here with no solution.
I'm working on a WCF streaming service over HTTP.
Here are my MessageContract
[MessageContract]
public class FileRequest
{
#region Message Header
[MessageHeader(MustUnderstand = true)]
public Credential Credentials { get; set; }
#endregion
#region Message body
[MessageBodyMember(Order = 1)]
public FileInfo FileInfo { get; set; }
#endregion
#region Ctor
// ...
#endregion
}
[MessageContract]
public class FileRequestResponse
{
#region Message Header
[MessageHeader(MustUnderstand = true)]
public FileInfo FileHeader { get; set; }
[MessageHeader(MustUnderstand = true)]
public OperationResult<bool> OperationResult { get; set; }
#endregion
#region Message Body
[MessageBodyMember]
public Stream FileStream { get; set; }
#endregion
#region Constructor
// ...
#endregion
}
Here is my ServiceContract
[ServiceContract(Namespace = "https://service.contract.example.com")]
public interface IUpdateService
{
[OperationContract(Action = "GetUpdates")]
OperationResult<List<FileInfo>> GetUpates(ApplicationInfo applicationInfo, Credential credential);
[OperationContract(Action = "GetFile")]
FileRequestResponse FileRequest(FileRequest fileRequest);
}
Now the question is why I am getting this error:
// CODEGEN: Generating message
contract since message FileRequest has
headers
When I add my service reference. The end result is that the service contract wraps the FileRequest operation into a wrapper which I do not want.
public FileInfo FileRequest(Credential Credentials, FileInfo, out OperationResult<bool> OperationResult, out System.IO.Stream FileStream)
NOTE:
I have not checked the "Always generate message contracts" in the service reference.
Set [MessageContract(IsWrapped=true)] for all the message contracts in the service and then try generating the proxy .
You might want to try to use the IsWrapped attribute on the message contract:
[MessageContract(IsWrapped=false)]
Not 100% sure which one you'll need (true or false) but that's one of the options you could try.
Also, another observation: I think it's a bit risky to have a method called FileRequest and a message contract which also is called FileRequest.
The generally accepted best practive would be to have a method GetFile, a request message for that called GetFileRequest and a response message type GetFileResponse. Do not use the same names for different things.
I have a WCF service with a client application. I have complete control over both the client and server implementation. I have hundreds of methods in the WCF contract which need a piece of information supplied by the client. Instead of modifying hundreds of methods, is there a way I can send specific data from the client with every call to the service, possibly somewhere in the channel?
Maybe when the client is setting up the proxy before making the call, it can store this data somewhere in an internal property of the proxy... the data would then get sent to the server and from within the service method I could inspect the OperationContext or some other piece of memory to get this data back and use it?
Any ideas?
It sounds like you are wanting something like headers like with SOAP webservices. I'm not a WCF expert, but this looks like the WCF equivalent.
It shouldn't actually be that hard. The best way I can think of is to write an IClientMessageInspector that adds a SOAP header into the Message.Headers in its BeforeSendRequest method.
See e.g. http://weblogs.asp.net/paolopia/archive/2007/08/23/writing-a-wcf-message-inspector.aspx
You can't do this trivially. It will take some work.
It's true that SOAP Headers are the perfect way to pass out-of-band data to and/or from a service. But you already have your contract defined, and adding headers will change the contract.
I believe you'll have to start using message contracts.
