Exemples
L'exemple suivant indique comment utiliser la propriété State pour ajouter un System.Runtime.Serialization.XsdDataContractImporter personnalisé afin d'importer des structures de données de manière particulière.
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();
}
Remarques
Utilisez la propriété State
pour ajouter ou supprimer des objets utilisés lors de l'importation de métadonnées.
