如何像<ns:From><ns:Address>###</ns:Address></ns:From>一样添加SOAP标头C#

Question

尝试将标头添加到

<ns:From><ns:Address>###</ns:Address></ns:From>

我使用了以下代码：

using (new OperationContextScope(client.InnerChannel)){
 var header = MessageHeader.CreateHeader("ns:From", "", "<ns:Address>###</ns:Address>");
}

但我得到了<ns:From>&lt;ns:Address&gt;###&lt;/ns:Address&gt;</ns:From>

请帮帮忙。

在线查找答案。

public class FromHeader : MessageHeader    {     
    public override string Name => "ns:From";
    public override string Namespace => "";
    protected override void OnWriteHeaderContents(XmlDictionaryWriter writer, MessageVersion messageVersion)
    {                       
        writer.WriteStartElement("ns:Address");
        writer.WriteString("###");
        writer.WriteEndElement();
    }
}


using (new OperationContextScope(client.InnerChannel))
{
OperationContext.Current.OutgoingMessageHeaders.Add( new FromHeader() );                
}
