Exemplos

Os exemplos de código a seguir mostram como derivar da classe ConfigurationConverterBase para criar um tipo de conversor de TimeSpan personalizado.The following code examples show how to derive from the ConfigurationConverterBase class to create a custom TimeSpan converter type. Além disso, os exemplos mostram como usar esse tipo em uma seção personalizada.Also, the examples show how to use this type in a custom section.

Comentários

O ConfigurationConverterBase é a classe base para os tipos de configuração do conversor.The ConfigurationConverterBase is the base class for the converter configuration types. Esses são tipos que convertem cadeias de caracteres, encontrados no arquivo de configuração, de e para as propriedades com rigidez de tipos relacionadas.These are types that convert strings, found in the configuration file, to and from the related strongly typed properties.

Construtores
