ExportOptions ExportOptions ExportOptions ExportOptions Class


表示 XsdDataContractExporter 可以設定的選項。Represents the options that can be set for an XsdDataContractExporter.

public ref class ExportOptions
public class ExportOptions
type ExportOptions = class
Public Class ExportOptions


下列範例會建立 ExportOptions 類別的執行個體,並將型別 (Possessions) 新增至 KnownTypes 屬性所傳回的集合。The following example creates an instance of the ExportOptions class and adds a type (Possessions) to the collection returned by the KnownTypes property.

XsdDataContractExporter 接著會匯出型別結構描述,包括加入至集合的 Possessions 型別。The XsdDataContractExporter then exports the schemas of the types, including the Possessions type added to the collection.

        XsdDataContractExporter exporter = new XsdDataContractExporter();
        if (exporter.CanExport(typeof(Employee)))
            Console.WriteLine("number of schemas: {0}", exporter.Schemas.Count);
            XmlSchemaSet mySchemas = exporter.Schemas;

            XmlQualifiedName XmlNameValue = exporter.GetRootElementName(typeof(Employee));
            string EmployeeNameSpace = XmlNameValue.Namespace;

XsdDataContractExporter 可用來從型別或組件產生 XSD 結構描述。The XsdDataContractExporter is used to generate XSD schemas from a type or assembly. 您也可以使用 XsdDataContractImporter 從結構描述文件中產生 .NET Framework.NET Framework 程式碼。You can also use the XsdDataContractImporter to generate .NET Framework.NET Framework code from a schema document.

如需有關匯入和匯出結構描述的詳細資訊,請參閱 < 結構描述匯入及匯出匯出類別中的結構描述For more information about importing and exporting schemas, see Schema Import and Export and Exporting Schemas from Classes.

KnownTypes 會使用 DataContractSerializer 屬性來包含可在物件圖形中讀取的型別。The KnownTypes property is used by the DataContractSerializer to include types that can be read in an object graph. 如需資料合約和已知型別的詳細資訊,請參閱 < Data Contract Known TypesFor more information about the data contract and known types, see Data Contract Known Types.

如需有關資料合約的詳細資訊,請參閱Using Data ContractsFor more information about data contracts, see Using Data Contracts.
