XsdDataContractImporter Class
Assembly: System.Runtime.Serialization (in system.runtime.serialization.dll)
Use the XsdDataContractImporter if you are creating a Web service that must interoperate with an existing Web service, or to create data contract types from XML schemas. XsdDataContractImporter will transform a set of XML schemas and create the .NET Framework types that represent the data contract in a selected programming language. To create the code, use the classes in the System.CodeDom namespace.
Conversely, use the XsdDataContractExporter class when you have created a Web service that incorporates data represented by CLR types and when you need to export XML schemas for each data type to be consumed by other Web services. That is, XsdDataContractExporter transforms a set of CLR types into a set of XML schemas.
Note: |
|---|
| To generate CLR types from XML schemas at design time, use the Service Model Metadata Utility Tool (Svcutil.exe). To generated code from XSD files, use the /dataContractOnly switch of the tool. You can also use the XsdDataContractImporter if you need more control over the process or need to do it programmatically. |
The following example uses creates an XmlSchemaSet and calls the Import method to create a CodeCompileUnit. The CodeCompileUnit is then used to create both Visual C# and Visual Basic code files.
