C# XML Element Prefix SOAP RRS feed

  • Question

  • User1358036820 posted

    I have seen many SO answers but non seem to help with the issue I have. What I am doing is calling a SOAP service from third party and it actually requires a prefix on element names. Example:


    I have created a client using Add service reference in VS. I have a class which is where i want the prefix on each property.

    public class WebsiteSoapHeader : System.Web.Services.Protocols.SoapHeader
    		public WebsiteSoapHeader()
    			xmlns.Add("test", "https://xxx/service");
    		public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();
    		[XmlElement(ElementName ="test",Namespace = "https://xxx/service")]
    		public string testprop { get; set; }

    As this does not get serialized manually it only produces

    <test xmlns="">test</test>

    Hi Chris

    I saw this but mine is a auto generated proxy from wsdl and i don't have those methods to work with.  At this point i'm using a manual approach with stringbuilder but not very clean.

    How did you use the generated proxy? I suggest you replace the binding in client side. For my above link, it set below code for service, you could also set it for client binding.

    Binding binding = ReplacePrefixMessageEncodingBindingElement.ReplaceEncodingBindingElement( 
                new WSHttpBinding(SecurityMode.None), 

    In addition, the link below shares another way to custom the Prefix.
