我是这个肥皂消息的新手，我在使用 WebService 时遇到了一些麻烦，我使用 WSDL.exe 创建了一个类，我遇到的第一个问题是在执行命令时，它使用 var[] 创建了一个参数[] 我不得不替换单个 var[] （数组）。

然后它成功编译，现在我遇到了一些问题，我不知道如何解决它：

我发送的请求是这样的：

<?xml version="1.0" encoding="utf-8"?>

当它到达服务器时，由于请求没有正确的格式，因此无法处理，正确的格式是这样的：

</soap:Envelope>

我需要切换：

1）在信封节点中，我需要添加一个新属性：

xmlns:neon="http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl"

2）在emitir节点上，我需要它<neon:emitir></neon:emitir>而不是常规<emitir>

当我这样做时，一切都像魅力一样，就像我说我用 wsdl.exe 工具创建了这个类，这是我正在使用的代码：

 [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace = "http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl", ResponseNamespace = "http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        [return: System.Xml.Serialization.XmlElementAttribute("RespuestaWS", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
        [WebServiceSOAPExtension]
        public respuestaWS emitirWS(comprobante comprobante)
        {
            object[] results = this.Invoke("emitirWS", new object[] {
                    comprobante});
            return ((respuestaWS)(results[0]));
        }

谢谢，我不知道从哪里开始。

好吧，对于那些试图做这样的事情而你不知道的人来说，我最终做了一些我不推荐的讨厌的事情，但是如果你像我一样被困住并且你不知道从哪里开始以“正确”的方式做到这一点，你可以这样做：

首先，您需要创建一个扩展类，SoapExtension如下所示：

namespace SoapExentender
{
    class WebServiceSOAPExtension : SoapExtension
    {
        Stream oldStream;
        Stream newStream;
        string filename;

    public override Stream ChainStream(Stream stream)
    {
        oldStream = stream;
        newStream = new MemoryStream();
        return newStream;
    }

    // When the SOAP extension is accessed for the first time, the XML Web service method it is applied to is accessed to store the file name passed in,

    //using the corresponding SoapExtensionAttribute.    
    public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
    {
        return null;
    }

    // The SOAP extension was configured to run using a configuration file instead of an attribute applied to a specific XML Web service method.
    public override object GetInitializer(Type WebServiceType)
    {
        return null;
    }

    // Receive the file name stored by GetInitializer and store it in a member variable for this specific instance.
    public override void Initialize(object initializer)
    {
        filename = ConfigurationManager.AppSettings["STOFacturacionDLL"].ToString();
    }

    //  If the SoapMessageStage is such that the SoapRequest or SoapResponse is still in the SOAP format to be sent or received, save it out to a file.
    public override void ProcessMessage(SoapMessage message)
    {
        switch (message.Stage)
        {
            case SoapMessageStage.BeforeSerialize:
                break;
            case SoapMessageStage.AfterSerialize: //el xml serializado de salida
                WriteOutput((SoapClientMessage)message);
                break;
            case SoapMessageStage.BeforeDeserialize:
                WriteInput((SoapClientMessage)message);
                break;
            case SoapMessageStage.AfterDeserialize:
                break;
            default:
                throw new Exception("Stage inválido");
        }
    }

    // Write the contents of the outgoing SOAP message to the log file.
    public void WriteOutput(SoapClientMessage message)
    {
        newStream.Position = 0;
        FileStream fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
        StreamWriter myStreamWriter = new StreamWriter(fs);
        myStreamWriter.WriteLine("================================== Fecha del request: " + DateTime.Now);
        // Print to the log file the request header field for SoapAction header.
        myStreamWriter.WriteLine(@"La acción SOAP del 'header' Http request  es: " + message.Action);

        // Print to the log file the method invoked by the client.
        myStreamWriter.WriteLine("El metodo llamado fue: " + message.MethodInfo.Name);

        // Print to the log file if the method invoked is OneWay.
        if (message.OneWay)
            myStreamWriter.WriteLine("El cliente no espera a que se termine el proceso (no es de un solo sentido)");
        else
            myStreamWriter.WriteLine("El cliente espera a que se termine el proceso");

        // Print to the log file the URL of the site that provides implementation of the method.
        myStreamWriter.WriteLine("La URL solicitada fue: " + message.Url);
        myStreamWriter.WriteLine("el contenido del request/response del ---- <soap:envelope> ---- es : ");
        myStreamWriter.Flush();

        Copy(newStream, fs);
        myStreamWriter.Close();
        //replace custom text
        string stringRequest = "";
        try
        {
            newStream.Position = 0;
            MemoryStream RequestStream = new MemoryStream();
            Copy(newStream, RequestStream);
            RequestStream.Position = 0;
            byte[] bytesRequestStream = ReadFully(RequestStream);
            stringRequest = System.Text.Encoding.UTF8.GetString(bytesRequestStream);
            stringRequest = replaceText(stringRequest, "<ReimprimirReferencia", "<thepanch:ReimprimirReferencia");
            int i = 0;
        }
        catch (Exception exc) { }

        newStream.Position = 0;
        //replace the original stream, with the custom stream
        Copy(ConvertStringToStream(stringRequest), oldStream);
    }

    private string replaceText(string MainString, string SearchString, string ReplaceWith)
    {
        MainString = MainString.Replace(SearchString, ReplaceWith);
        return MainString;
    }

    private MemoryStream ConvertStringToStream(string RequestString)
    {
        byte[] byteArray = Encoding.UTF8.GetBytes(RequestString);
        MemoryStream stream = new MemoryStream(byteArray);
        stream.Position = 0;
        return stream;
    }

    private byte[] ReadFully(Stream input)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            input.CopyTo(ms);
            return ms.ToArray();
        }
    }

    public void WriteInput(SoapMessage message)
    {
        Copy(oldStream, newStream);
        FileStream fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
        StreamWriter w = new StreamWriter(fs);
        string soapString = (message is SoapServerMessage) ? "SoapRequest" : "SoapResponse";
        w.WriteLine("----------" + soapString + " at " + DateTime.Now);
        w.Flush();
        newStream.Position = 0;
        Copy(newStream, fs);
        w.Close();
        newStream.Position = 0;
    }

    void Copy(Stream from, Stream to)
    {
        TextReader reader = new StreamReader(from);
        TextWriter writer = new StreamWriter(to);
        writer.WriteLine(reader.ReadToEnd());
        writer.Flush();
    }
}

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class WebServiceSOAPExtensionAttribute : SoapExtensionAttribute
{
    private int priority;

    public override Type ExtensionType
    {
        get { return typeof(WebServiceSOAPExtension); }
    }

    public override int Priority
    {
        get { return priority; }
        set { priority = value; }
    }
}

}

然后在代理方法上使用自定义属性将实际 Stream 替换为您的自定义流，writeOutput 方法用于“请求”，writeInput 方法用于“响应”，然后您需要使用您的字符串来适应您的需求，希望对您有所帮助。

正如我在第一行中提到的，这不是正确的方法，但是如果你像我一样不知道从哪里开始，你可以编写你的自定义 Xml 字符串。
