Eccezioni

InvalidOperationException

WsdlImporter ha riscontrato un errore.

Esempio

Nell'esempio di codice seguente viene illustrato come utilizzare l'oggetto WsdlImporter per aggiungere un'interfaccia System.Runtime.Serialization.IDataContractSurrogate personalizzata, importare tutti i contratti, compilarli e salvarli in un file.

  static void GenerateCSCodeForService(EndpointAddress metadataAddress, string outputFile)
  {
MetadataExchangeClient mexClient = new MetadataExchangeClient(metadataAddress);
mexClient.ResolveMetadataReferences = true;
MetadataSet metaDocs = mexClient.GetMetadata();

      WsdlImporter importer = new WsdlImporter(metaDocs);
ServiceContractGenerator generator = new ServiceContractGenerator();

// Add our custom DCAnnotationSurrogate
// to write XSD annotations into the comments.
object dataContractImporter;
XsdDataContractImporter xsdDCImporter;
if (!importer.State.TryGetValue(typeof(XsdDataContractImporter), out dataContractImporter))
{
  Console.WriteLine("Couldn't find the XsdDataContractImporter! Adding custom importer.");
  xsdDCImporter = new XsdDataContractImporter();
  xsdDCImporter.Options = new ImportOptions();
  importer.State.Add(typeof(XsdDataContractImporter), xsdDCImporter);
}
else
{
  xsdDCImporter = (XsdDataContractImporter)dataContractImporter;
  if (xsdDCImporter.Options == null)
  {
    Console.WriteLine("There were no ImportOptions on the importer.");
    xsdDCImporter.Options = new ImportOptions();
  }
}
xsdDCImporter.Options.DataContractSurrogate = new DCAnnotationSurrogate();

// Uncomment the following code if you are going to do your work programmatically rather than add
// the WsdlDocumentationImporters through a configuration file.
/*
// The following code inserts a custom WsdlImporter without removing the other
// importers already in the collection.
System.Collections.Generic.IEnumerable<IWsdlImportExtension> exts = importer.WsdlImportExtensions;
System.Collections.Generic.List<IWsdlImportExtension> newExts
  = new System.Collections.Generic.List<IWsdlImportExtension>();
foreach (IWsdlImportExtension ext in exts)
{
  Console.WriteLine("Default WSDL import extensions: {0}", ext.GetType().Name);
  newExts.Add(ext);
}
newExts.Add(new WsdlDocumentationImporter());
System.Collections.Generic.IEnumerable<IPolicyImportExtension> polExts = importer.PolicyImportExtensions;
importer = new WsdlImporter(metaDocs, polExts, newExts);
*/

System.Collections.ObjectModel.Collection<ContractDescription> contracts
  = importer.ImportAllContracts();
importer.ImportAllEndpoints();
      foreach (ContractDescription contract in contracts)
      {
          generator.GenerateServiceContractType(contract);
      }
if (generator.Errors.Count != 0)
  throw new Exception("There were errors during code compilation.");

// Write the code dom
System.CodeDom.Compiler.CodeGeneratorOptions options
  = new System.CodeDom.Compiler.CodeGeneratorOptions();
      options.BracingStyle = "C";
      System.CodeDom.Compiler.CodeDomProvider codeDomProvider
  = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("C#");
      System.CodeDom.Compiler.IndentedTextWriter textWriter
  = new System.CodeDom.Compiler.IndentedTextWriter(new System.IO.StreamWriter(outputFile));
      codeDomProvider.GenerateCodeFromCompileUnit(
  generator.TargetCompileUnit, textWriter, options
);
      textWriter.Close();
  }

Commenti

Utilizzare il metodo ImportAllContracts per importare tutte le informazioni sui tipi di porta WSDL dai documenti dei metadati e restituirle come oggetti ContractDescription. È consigliabile controllare la proprietà Errors per accertare l'eventuale esistenza di errori di importazione prima di utilizzare gli oggetti restituiti.

Per importare solo un tipo di porta, vedere il metodo ImportContract.
