C# XML Element Prefix SOAP

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:

<pref:test>test</pref:test>

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");
		}

		[XmlNamespaceDeclarations]
		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 Ammd,

Take a look the following article.

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), 
            namespaceToPrefixMapping);

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