Belangrijk

Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.

Hiermee wordt een waarde opgehaald die aangeeft of een CLR-type (Common Language Runtime) (of set typen) kan worden geëxporteerd.

Overloads

Name	Description
CanExport(ICollection<Assembly>)	Hiermee wordt een waarde opgehaald die aangeeft of de set CLR-typen (Common Language Runtime) in een set assembly's kan worden geëxporteerd.
CanExport(ICollection<Type>)	Hiermee wordt een waarde opgehaald die aangeeft of de set CLR-typen (Common Language Runtime) in een ICollection<T> kan worden geëxporteerd.
CanExport(Type)	Hiermee wordt een waarde opgehaald die aangeeft of het opgegeven CLR-type (Common Language Runtime) kan worden geëxporteerd.

Opmerkingen

Niet alle CLR-typen kunnen worden gebruikt in gegevenscontracten. Zie Typen die worden ondersteund door de Serializer van het gegevenscontract voor meer informatie over wat kan worden geserialiseerd.

Voorbeelden

In het volgende voorbeeld wordt de CanExport(Type) methode aangeroepen voordat de Export(Type) methode wordt aangeroepen.

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()

    If exporter.CanExport(GetType(Employee)) Then
        exporter.Export(GetType(Employee))
