Exemplos

O exemplo de código a seguir exibe uma cadeia de caracteres original, as cadeias de caracteres geradas pelo ToString método para chaves de classificação que diferenciam maiúsculas de minúsculas e que não diferenciam maiúsculas de minúsculas e os dados de chave para chaves de classificação que diferenciam maiúsculas de minúsculas e não diferencia maiúsculas de minúsculas.

Comentários

O valor retornado é a concatenação da cadeia de caracteres "SortKey - ", o identificador de cultura e as opções de comparação do objeto atual SortKey e o valor da OriginalString propriedade .

Este método substitui Object.ToString.
