Valor da propriedade

CompilerType

Um somente CompilerType leitura que representa as configurações do gerador de código, do compilador de código e do compilador usados para criar o código-fonte para o caminho virtual. A classe base retorna null.

Exemplos

O exemplo de código a seguir ilustra uma implementação simples do provedor de build, herdando da classe base abstrata BuildProvider . O provedor de build substitui os CodeCompilerTypemembros e GenerateCode membros GetGeneratedTypeda classe base.

Comentários

Use a CodeCompilerType propriedade para fornecer as configurações para compilar o código-fonte para uma implementação de BuildProvider. A CodeCompilerType propriedade será null se o provedor de build não exigir uma linguagem de código específica para gerar e compilar o código-fonte.

Para definir o valor de um CompilerType objeto dentro de uma implementação do provedor de build, use o método ou GetDefaultCompilerTypeForLanguage o GetDefaultCompilerType método.

A CodeDomProviderType propriedade especifica a CodeDomProvider implementação usada para gerar e compilar o código-fonte para um provedor de build. A CompilerParameters propriedade define as configurações usadas para compilar o código-fonte em um assembly.
