C# ServiceDescriptionImporter NoCodeGenerated 我找不到问题

Question

嘿，我运行遇到了 ServiceDescription 导入器的情况。

在代码（粘贴在下面）中，我正在尝试从 WSDL 文件（存储在本地）导入和编译服务引用，遗憾的是，由于客户的影响，我不允许共享此 wsdl 文件。

然而，所有代码都运行良好，但以下行：

ServiceDescriptionImportWarnings warnings = importer.Import(nm, unit);

不断返回：ServiceDescriptionImportWarnings.NoCodeGenerated

有人可以告诉我这段代码是否有问题吗？

public string[] GenerateProxyAssembly(string pathOrURL)
{
    Stream stream = File.OpenRead(pathOrURL);
    ServiceDescription desc = ServiceDescription.Read(stream);

    //find out the number of operations exposed by the web service
    //store the name of the operations inside the string array
    //iterating only through the first binding exposed as
    //the rest of the bindings will have the same number

    int i = 0;
    Binding binding = desc.Bindings[0];
    OperationBindingCollection opColl = binding.Operations;
    string[] listOfOperations = new string[opColl.Count];

    foreach (OperationBinding operation in opColl)
    {
        listOfOperations[i++] = operation.Name;
    }

    //initializing a ServiceDescriptionImporter object
    ServiceDescriptionImporter importer = new ServiceDescriptionImporter();

    //set the protocol to SOAP 1.1
    importer.ProtocolName = "Soap12";

    //setting the Style to Client in order to generate client proxy code
    importer.Style = ServiceDescriptionImportStyle.Client;

    //adding the ServiceDescription to the Importer object
    importer.AddServiceDescription(desc, null, null);
    importer.CodeGenerationOptions = CodeGenerationOptions.GenerateNewAsync;

    //Initialize the CODE DOM tree in which we will import the 
    //ServiceDescriptionImporter
    CodeNamespace nm = new CodeNamespace("test");
    CodeCompileUnit unit = new CodeCompileUnit();
    unit.Namespaces.Add(nm);

    //generating the client proxy code
    ServiceDescriptionImportWarnings warnings = importer.Import(nm, unit);

    if (warnings == 0)
    {
        //set the CodeDOMProvider to C# to generate the code in C#
        System.IO.StringWriter sw = new System.IO.StringWriter();
        CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
        provider.GenerateCodeFromCompileUnit(unit, sw, new CodeGeneratorOptions());

        //creating TempFileCollection
        //the path of the temp folder is hardcoded
        TempFileCollection coll = new TempFileCollection(@"C:\wmpub\tempFiles");
        coll.KeepFiles = false;

        //setting the CompilerParameters for the temporary assembly
        string[] refAssembly = { "System.dll", "System.Data.dll",
                                         "System.Web.Services.dll", "System.Xml.dll" };
        CompilerParameters param = new CompilerParameters(refAssembly);
        param.GenerateInMemory = true;
        param.TreatWarningsAsErrors = false;
        param.OutputAssembly = "WebServiceReflector.dll";
        param.TempFiles = coll;

        //compile the generated code into an assembly
        //CompilerResults results = provider.CompileAssemblyFromDom(param, unitArr);
        CompilerResults results = provider.CompileAssemblyFromSource(param, sw.ToString());
        this.assem = results.CompiledAssembly;
    }

    //return the list of operations exposed by the web service
    return listOfOperations;
}

你分享的信息不够，我会尽力解答。

协议可能是问题所在，我遇到了类似的问题，删除这一行解决了问题

importer.ProtocolName = "Soap12";

因此，就我而言，我尝试使用错误的协议设置连接到 Soap 1.1 服务。 Soap 1.1 是默认值。
