Gets a value indicating whether the serializer can be loaded with the currently installed version of .NET.

Public ReadOnly Property IsLoadable As Boolean
true
if the serializer assembly can be loaded; otherwise, false
. The default is false
.
The following examples illustrate using IsLoadable to determine if the associated plug-in serializer can be loaded and used.
// ------------------------ 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.
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;
}
IsLoadable should be false
unless AssemblyVersion has the same value as WinFXVersion.
