Exemplos

O exemplo de código a seguir abre o repositório de certificados do usuário atual, seleciona somente certificados ativos e, em seguida, permite que o usuário selecione um ou mais certificados.The following code example opens the current user certificate store, selects only active certificates, then allows the user to select one or more certificates. Em seguida, o exemplo grava informações de certificado no console.The example then writes certificate information to the console.
