Parâmetros

Devoluções

Um objeto que é equivalente à data e hora contidas em s.

Exceções

Exemplos

O exemplo seguinte analisa a representação da cadeia de vários valores de data e hora por:

• Usando o fornecedor de formato padrão, que fornece as convenções de formatação da cultura atual do computador usada para produzir o resultado de exemplo. O resultado deste exemplo reflete as convenções de formatação da cultura en-US.

• Usando o valor de estilo padrão, que é AllowWhiteSpaces.

Lida com a FormatException exceção que é lançada quando o método tenta analisar a representação da string de uma data e hora usando convenções de formatação de outras culturas. Também mostra como analisar com sucesso um valor de data e hora que não utiliza as convenções de formatação da cultura atual.

Observações

Se s contiver informação de fuso horário, este método devolve um DateTime valor cuja Kind propriedade é DateTimeKind.Local e converte a data e hora em s hora local. Caso contrário, não realiza conversão de fuso horário e devolve um DateTime valor cuja Kind propriedade é DateTimeKind.Unspecified.

Esta sobrecarga tenta analisar s usando as convenções de formatação da cultura atual. A cultura atual é indicada pela CurrentCulture propriedade. Para analisar uma string usando as convenções de formatação de uma cultura específica, chame os Parse(String, IFormatProvider) ou os Parse(String, IFormatProvider, DateTimeStyles) overloads.

Esta sobrecarga tenta analisar s usando DateTimeStyles.AllowWhiteSpaces estilo.
