Comentários
Um designer pode utilizar IDesignerSerializationManager para acessar serviços úteis para gerenciar processos de serialização em tempo de design. Por exemplo, uma classe que implementa o gerenciador de serialização do designer pode usar essa interface para criar objetos, pesquisar tipos, identificar objetos e personalizar a serialização de tipos específicos.
Propriedades
| Context |
Obtém uma área de armazenamento baseada em pilha e definida pelo usuário que é útil para a comunicação entre os serializadores. |
| Properties |
Indica as propriedades personalizadas que podem ser serializáveis com serializadores disponíveis. |
Métodos
| AddSerializationProvider(IDesignerSerializationProvider) |
Adiciona o provedor de serialização especificado ao gerenciador de serialização. |
| CreateInstance(Type, ICollection, String, Boolean) |
Cria uma instância do tipo especificado e adiciona-a a uma coleção de instâncias nomeadas. |
| GetInstance(String) |
Obtém uma instância de um objeto criado do nome especificado ou |
| GetName(Object) |
Obtém o nome do objeto especificado ou |
| GetSerializer(Type, Type) |
Obtém um serializador do tipo solicitado para o tipo de objeto especificado. |
| GetService(Type) |
Obtém o objeto de serviço do tipo especificado. (Herdado de IServiceProvider) |
| GetType(String) |
Obtém um tipo do nome especificado. |
| RemoveSerializationProvider(IDesignerSerializationProvider) |
Remove um provedor de serialização personalizado do gerenciador de serialização. |
| ReportError(Object) |
Relata um erro na serialização. |
| SetName(Object, String) |
Define o nome do objeto especificado existente. |
Eventos
| ResolveName |
Ocorre quando GetName(Object) não consegue localizar o nome especificado na tabela de nomes do gerenciador de serialização. |
| SerializationComplete |
Ocorre quando a serialização é concluída. |
