Observações

Depois de a ClaimSet classe ter sido criada, não pode ser alterada.

Examinar o conteúdo de um ClaimSet para tipos específicos de declarações é uma tarefa comum ao usar a autorização baseada em declarações. Para examinar um ClaimSet quanto à presença de alegações específicas, use o método FindClaims. O método oferece melhor desempenho do que iterar diretamente sobre o ClaimSet.
