MetadataImporter.State MetadataImporter.State MetadataImporter.State MetadataImporter.State Property

Definition

Gets or sets a collection of objects used in the importing of metadata.

public:
 property System::Collections::Generic::Dictionary<System::Object ^, System::Object ^> ^ State { System::Collections::Generic::Dictionary<System::Object ^, System::Object ^> ^ get(); };
public System.Collections.Generic.Dictionary<object,object> State { get; }
member this.State : System.Collections.Generic.Dictionary<obj, obj>
Public ReadOnly Property State As Dictionary(Of Object, Object)

Property Value

A dictionary of objects keyed by type.

Examples

The following example shows the use of the State property to add a custom System.Runtime.Serialization.XsdDataContractImporter to import data structures in a particular way.

       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();
       }

Remarks

Use the State property to add or remove objects used in the importing of metadata.
