Examples

The following examples show use of the SerializerProvider constructor.

// ------------------------ PlugInFileFilter --------------------------
/// <summary>
///   Gets a filter string for installed plug-in serializers.</summary>
/// <remark>
///   PlugInFileFilter is used to set the SaveFileDialog or
///   OpenFileDialog "Filter" property when saving or opening files
///   using plug-in serializers.</remark>
private string PlugInFileFilter
{
    get
    {   // Create a SerializerProvider for accessing plug-in serializers.
        SerializerProvider serializerProvider = new SerializerProvider();
        string filter = "";

        // For each loadable serializer, add its display
        // name and extension to the filter string.
        foreach (SerializerDescriptor serializerDescriptor in
            serializerProvider.InstalledSerializers)
        {
            if (serializerDescriptor.IsLoadable)
            {
                // After the first, separate entries with a "|".
                if (filter.Length > 0)   filter += "|";

                // Add an entry with the plug-in name and extension.
                filter += serializerDescriptor.DisplayName + " (*" +
                    serializerDescriptor.DefaultFileExtension + ")|*" +
                    serializerDescriptor.DefaultFileExtension;
            }
        }

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

// Create a SerializerProvider for accessing plug-in serializers.

// 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;
}

Remarks

Only fully trusted callers can create a SerializerProvider.
