public static bool DeleteProfile (string username);

static member DeleteProfile : string -> bool

Public Shared Function DeleteProfile (username As String) As Boolean

Parâmetros

username: String

O nome de usuário do perfil a ser excluído.

Boolean

true se o perfil do usuário foi encontrado e excluído, caso contrário, false.

Exceções

ArgumentException

Exemplos

O exemplo de código a seguir mostra uma página ASP.NET que gerencia perfis inativos. O DeleteProfile método é chamado quando um único perfil é selecionado para ser excluído. Se um perfil é considerado inativo é baseado na data especificada para o valor do userInactiveSinceDate parâmetro passado para o GetAllInactiveProfiles método .

Importante

Este exemplo contém uma caixa de texto que aceita a entrada do usuário, que é uma possível ameaça à segurança. Por padrão, ASP.NET páginas da Web validam que a entrada do usuário não inclui elementos html ou script. Para obter mais informações, consulte Visão geral de explorações de script.

Comentários

O DeleteProfile método exclui todas as informações de perfil e propriedades do perfil do usuário para o especificado username da fonte de dados para o especificado ApplicationName.

O DeleteProfile método chama o DeleteProfiles método do provedor de perfil padrão para executar a operação de exclusão. O provedor de perfil padrão é especificado usando o defaultProvider atributo do elemento de configuração de perfil . Se o perfil do usuário contiver propriedades gerenciadas por um provedor de perfil diferente do provedor padrão, elas não serão excluídas. Para excluir propriedades de perfil gerenciadas por um provedor de perfil diferente do provedor padrão, obtenha uma referência ao provedor de perfil usando a Providers propriedade e chame o DeleteProfiles método do provedor diretamente.
