範例

以下範例說明了使用該 ServiceDescriptionImporter 類別產生代理客戶端程式碼，呼叫由 WSDL 檔案描述的 XML Web 服務。

#using <System.Xml.dll>
#using <System.Web.Services.dll>
#using <System.dll>

using namespace System;
using namespace System::Web::Services::Description;
using namespace System::CodeDom;
using namespace System::CodeDom::Compiler;

int main()
{
   // Get a WSDL file describing a service.
   ServiceDescription^ description = ServiceDescription::Read( "service.wsdl" );

   // Initialize a service description importer.
   ServiceDescriptionImporter^ importer = gcnew ServiceDescriptionImporter;
   importer->ProtocolName = "Soap12"; // Use SOAP 1.2.
   importer->AddServiceDescription( description, nullptr, nullptr );

   // Report on the service descriptions.
   Console::WriteLine( "Importing {0} service descriptions with {1} associated schemas.", importer->ServiceDescriptions->Count, importer->Schemas->Count );

   // Generate a proxy client.
   importer->Style = ServiceDescriptionImportStyle::Client;

   // Generate properties to represent primitive values.
   importer->CodeGenerationOptions = System::Xml::Serialization::CodeGenerationOptions::GenerateProperties;

   // Initialize a Code-DOM tree into which we will import the service.
   CodeNamespace^ nmspace = gcnew CodeNamespace;
   CodeCompileUnit^ unit = gcnew CodeCompileUnit;
   unit->Namespaces->Add( nmspace );
   
   // Import the service into the Code-DOM tree. This creates proxy code
   // that uses the service.
   ServiceDescriptionImportWarnings warning = importer->Import(nmspace,unit);
   if ( warning == (ServiceDescriptionImportWarnings)0 )
   {
      // Generate and print the proxy code in C#.
      CodeDomProvider^ provider = CodeDomProvider::CreateProvider( "CSharp" );
      ICodeGenerator^ generator = provider->CreateGenerator();
      generator->GenerateCodeFromCompileUnit( unit, Console::Out, gcnew CodeGeneratorOptions );
   }
   else
   {
      // Print an error message.
      Console::WriteLine( warning );
   }
}

using System;
using System.Web.Services.Description;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Security.Permissions;

public class Import {

    public static void Main() 
    {
        Run();
    }

    [PermissionSetAttribute(SecurityAction.Demand, Name = "Full Trust")]
    public static void Run()
    {
    // Get a WSDL file describing a service.
    ServiceDescription description = ServiceDescription.Read("service.wsdl");

    // Initialize a service description importer.
    ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
    importer.ProtocolName = "Soap12";  // Use SOAP 1.2.
    importer.AddServiceDescription(description,null,null);

    // Report on the service descriptions.
    Console.WriteLine("Importing {0} service descriptions with {1} associated schemas.",
                      importer.ServiceDescriptions.Count, importer.Schemas.Count);

    // Generate a proxy client.
    importer.Style = ServiceDescriptionImportStyle.Client;

    // Generate properties to represent primitive values.
    importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;

    // Initialize a Code-DOM tree into which we will import the service.
    CodeNamespace nmspace = new CodeNamespace();
    CodeCompileUnit unit = new CodeCompileUnit();
    unit.Namespaces.Add(nmspace);

    // Import the service into the Code-DOM tree. This creates proxy code
    // that uses the service.
    ServiceDescriptionImportWarnings warning = importer.Import(nmspace,unit);

    if (warning == 0)
    {
        // Generate and print the proxy code in C#.
        CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
        provider.GenerateCodeFromCompileUnit(unit, Console.Out, new CodeGeneratorOptions() );
    }
    else
    {
        // Print an error message.
        Console.WriteLine(warning); 
    }
}
}

備註

XML 網路服務的介面通常由網路服務描述語言（WSDL）檔案描述。 例如，若要取得使用 http://localhost/service.asmx 暴露的 ASP.NET 的 WSDL 網路服務描述，只需導覽至 http://localhost/service.asmx?WSDL。

這個 ServiceDescriptionImporter 類別讓你能輕鬆地將 WSDL 描述中的資訊匯入物件 System.CodeDom.CodeCompileUnit 中。 透過調整參數值 Style ，你可以指示實 ServiceDescriptionImporter 例產生一個客戶端代理類別，透過透明呼叫來提供 Web 服務的功能，或產生一個抽象類別，封裝 Web 服務的功能而不實作。

所得 CodeCompileUnit 物件中的程式碼可以直接呼叫，或以你選擇的語言匯出。
