O exemplo a seguir mostra como usar o método AddPackage.

    ShowStatus("   CANNOT DECRYPT!");

    MessageBox.Show("Unable to get Package.");
    return false;
}

// Set a PackageStore Uri reference for the encrypted stream.

//  that XamlReader uses to access the encrypted data stream.)

// Add the URI package
PackageStore.AddPackage(packageUri, _xpsPackage);
// Determine the starting part for the package.
PackagePart startingPart = GetPackageStartingPart(_xpsPackage);

// Set the DocViewer.Document property.

Comentários

packageUri define o URI de chave do pacote que é comparado quando você chama PackWebRequest.

Se o packageUri corresponder ao Uri de um PackagePart em uma PackWebRequest chamada, o pacote definido no PackageStore será usado para acessar a parte solicitada.

Se o packageUri não corresponder ao Uri de um PackagePart em uma PackWebRequest chamada, o pacote com o URI especificado será aberto para acessar a parte solicitada.

Observação de segurança Esse método exige todos os tipos personalizados EnvironmentPermissionPackage (nãoZipPackage).
