XsdDataContractExporter.CanExport Метод

Определение

Возвращает значение, указывающее, можно ли экспортировать тип среды CLR (или набор типов).

Перегрузки

Имя Описание
CanExport(ICollection<Assembly>)

Возвращает значение, указывающее, можно ли экспортировать набор типов среды CLR, содержащихся в наборе сборок.

CanExport(ICollection<Type>)

Возвращает значение, указывающее, можно ли экспортировать набор типов среды CLR, содержащихся в объекте ICollection<T> .

CanExport(Type)

Возвращает значение, указывающее, можно ли экспортировать указанный тип среды CLR.

Комментарии

Не все типы СРЕДЫ CLR можно использовать в контрактах данных. Дополнительные сведения о том, что можно сериализовать, см. в разделе "Типы, поддерживаемые сериализатором контракта данных".

Примеры

В следующем примере метод вызывается CanExport(Type) перед вызовом Export(Type) метода.

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

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

        foreach (XmlSchema schema in mySchemas.Schemas(EmployeeNameSpace))
        {
            schema.Write(Console.Out);
        }
    }
}
Shared Sub ExportXSD() 

    Dim exporter As New XsdDataContractExporter()

    ' Use the ExportOptions to add the Possessions type to the 
    ' collection of KnownTypes. 
    Dim eOptions As New ExportOptions()
