SerializerDescriptor Class

SerializerDescriptor Class

Provides information about installed plug-in serializers. This class cannot be inherited.

Namespace: System.Windows.Documents.Serialization
Assembly: PresentationFramework (in presentationframework.dll)

public sealed class SerializerDescriptor
public final class SerializerDescriptor
public final class SerializerDescriptor
You cannot use this managed class in XAML.

Plug-in serializer classes derive from and implement the ISerializerFactory interface.

The following examples illustrate using a SerializerDescriptor to return information on installed plug-in serializers. For the complete sample, see Document Serialization Sample.

// Create a SerializerProvider for accessing plug-in serializers.
SerializerProvider serializerProvider = new SerializerProvider();

// Locate the serializer that matches the fileName extension.
SerializerDescriptor selectedPlugIn = null;
foreach ( SerializerDescriptor serializerDescriptor in
                serializerProvider.InstalledSerializers )
{
    if ( serializerDescriptor.IsLoadable &&
         fileName.EndsWith(serializerDescriptor.DefaultFileExtension) )
    {   // The plug-in serializer and fileName extensions match.
        selectedPlugIn = serializerDescriptor;
        break; // foreach
    }
}

// If a match for a plug-in serializer was found,
// use it to output and store the document.
if (selectedPlugIn != null)
{
    Stream package = File.Create(fileName);
    SerializerWriter serializerWriter =
        serializerProvider.CreateSerializerWriter(selectedPlugIn,
                                                  package);
    IDocumentPaginatorSource idoc =
        flowDocument as IDocumentPaginatorSource;
    serializerWriter.Write(idoc.DocumentPaginator, null);
    package.Close();
    return true;
}

        foreach (SerializerDescriptor serializerDescriptor in

        {

            }
        }

        // Return the filter string of installed plug-in serializers.
        return filter;
    }
