ServiceDescriptionImporter无法找到Web服务命名空间的定义

我想知道是否有人知道如何克服我在使用ServiceDescriptionImporter时遇到的问题。我使用CodeDOM动态生成Web服务客户端代理,当Web服务WSDL嵌入了类型模式时,以下代码工作正常,但是当WSDL包含导入时,以下代码将生成错误,无法找到类型定义。我在网上做了一些研究并添加了一些代码来将模式添加到导入程序,但是在为导入的WSDL创建代理时仍然会收到错误。

Stream stream = client.OpenRead(wsURL);

ServiceDescription description = ServiceDescription.Read(stream);

ServiceDescriptionImporter importer = new ServiceDescriptionImporter();

importer.ProtocolName = "Soap12"; // Use SOAP 1.2.

importer.AddServiceDescription(description, null, null);

// Add any imported files
foreach (System.Xml.Schema.XmlSchema wsdlSchema in description.Types.Schemas)
{
    foreach (System.Xml.Schema.XmlSchemaObject externalSchema in wsdlSchema.Includes)
    {
        if (externalSchema is System.Xml.Schema.XmlSchemaImport)
        {
            Uri baseUri = new Uri(wsURL);
            Uri schemaUri = new Uri(baseUri, ((System.Xml.Schema.XmlSchemaExternal)externalSchema).SchemaLocation);
            stream = client.OpenRead(schemaUri);
            System.Xml.Schema.XmlSchema schema = System.Xml.Schema.XmlSchema.Read(stream, null);
            importer.Schemas.Add(schema);
        }
    }
}

importer.Style = ServiceDescriptionImportStyle.Client;

importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;

CodeNamespace nmspace = new CodeNamespace();
CodeCompileUnit unit1 = new CodeCompileUnit();

unit1.Namespaces.Add(nmspace);

// This is generating the error:
ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);

收到的错误:

  

找不到'xyz'的定义。缺少名称空间“xyz”的服务描述。   参数名称:名称

WSDL:

这个(servicedescriptionimporter)不在.net的4.0框架中。 所以你可以做的是更新到visual studio 2012(.net framework 4.5所需的最低要求)。

我发现了一个有类似问题的帖子:

ServiceDescription Importer and Import directives in the root WSDL

如果我注释掉外部架构对象的检查并使用帖子中的代码,这个问题似乎在这个WSDL上解决了:

if (externalSchema is XmlSchemaImport)

我不知道为什么这项工作,有谁知道为什么?
