Question

我从Web服务构建文件Service.dll以供使用。现在，我想自动更新文件Service.dll，以便更改Web服务。目前，我的方法是保存WSDL，用于将Web服务描述为Service.dll资源，然后将此资源中的WSDL与直接来自Web服务的WSDL进行比较，如果它们不同，我将更新文件Service.dll。这是我的代码C＃：

 public ServiceInspector(Uri serviceLocation)
    {
        if (serviceLocation.Query == string.Empty)
        {
            UriBuilder uriB = new UriBuilder(serviceLocation);

            uriB.Query = "WSDL";

            serviceLocation = uriB.Uri;
        }

        _serviceLocation = serviceLocation;

        WebRequest wsdlWebRequest = WebRequest.Create(serviceLocation);
        Stream wsdlRequestStream = wsdlWebRequest.GetResponse().GetResponseStream();

        //Get the ServiceDescription from the WSDL file
        ServiceDescription sd = ServiceDescription.Read(wsdlRequestStream);
        string wsdlPath = @"C:\Users\John\Downloads\Compressed\Core\TestApp\Ref\Service.wsdl";
        sd.Write(wsdlPath);

        string sdName = sd.Services[0].Name;

        ServiceDescriptionImporter sdImport = new ServiceDescriptionImporter();
        sdImport.AddServiceDescription(sd, String.Empty, String.Empty);
        sdImport.ProtocolName = "Soap";
        sdImport.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties;

        CodeNamespace codeNameSpace = new CodeNamespace();
        CodeCompileUnit codeCompileUnit = new CodeCompileUnit();
        codeCompileUnit.Namespaces.Add(codeNameSpace);

        ServiceDescriptionImportWarnings warnings = sdImport.Import(codeNameSpace, codeCompileUnit);

        if (warnings == 0)
        {
            StringWriter stringWriter = new StringWriter(System.Globalization.CultureInfo.CurrentCulture);
            Microsoft.CSharp.CSharpCodeProvider prov = new Microsoft.CSharp.CSharpCodeProvider();

            prov.GenerateCodeFromNamespace(codeNameSpace, stringWriter, new CodeGeneratorOptions());

            //Compile the assembly
            string[] assemblyReferences = new string[2] { "System.Web.Services.dll", "System.Xml.dll" };
            CompilerParameters param = new CompilerParameters(assemblyReferences);

            param.GenerateExecutable = false;
            param.GenerateInMemory = false;
            param.TreatWarningsAsErrors = false;
            param.WarningLevel = 4;
            //Embedd wsdl into Resources
            param.EmbeddedResources.Add(wsdlPath);
            param.OutputAssembly = @"C:\Users\John\Downloads\Compressed\Core\TestApp\Ref\Service.dll";

            CompilerResults results = new CompilerResults(new TempFileCollection());
            results = prov.CompileAssemblyFromDom(param, codeCompileUnit);

            Assembly assembly = results.CompiledAssembly;
        }
    }

方法检查wsdl已更改：

 private static bool IsServiceChanged(Uri uri)
    {
        Assembly assembly = Assembly.LoadFile(@"C:\Users\John\Downloads\Compressed\Core\TestApp\Ref\Service.dll");
        Stream stream = assembly.GetManifestResourceStream("Service.wsdl");

        if (string.IsNullOrEmpty(uri.Query))
        {
            UriBuilder uriBuilder = new UriBuilder(uri);
            uriBuilder.Query = "WSDL";
            uri = uriBuilder.Uri;
        }

        System.Net.WebRequest wsdlWebRequest = System.Net.WebRequest.Create(uri);

        using (Stream wsdlRequestStream = wsdlWebRequest.GetResponse().GetResponseStream())
        using (StreamReader reader = new StreamReader(stream))
        using (StreamReader reader2 = new StreamReader(wsdlRequestStream))
        {
            string result = reader.ReadToEnd();
            string result2 = reader2.ReadToEnd();
            if (string.Compare(result, result2, StringComparison.Ordinal) != 0)
            {
                return true;
            }
        }
        return false;
    }

当前，我的方法IsServiceChanged(Uri uri)始终返回True，因为写入文件的文件wsdl已更改排序顺序命名空间。 E.g：

<wsdl:definitions xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"....

这是wsdl直接从Web服务获取，然后写入文件，它将成为：

<wsdl:definitions xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:s="http://www.w3.org/2001/XMLSchema"

请给我一个更新此Service.dll的最佳解决方案？谢谢你的帮助！

如何比较两个Web服务描述（wsdl）？
