Comment obtenir le numéro de série de l'appareil : IMEI et le IMSI en C#
Le code IMEI (identité internationale d'équipement mobile : International Mobile Equipment Identity, IMEI) est un numéro qui permet d'identifier de manière unique chacun des terminaux mobiles (ME) GSM ou UMTS, la norme prévoit que ces derniers embarquent un identifiant.
Le code IMSI (International Mobile Subscriber Identity) est un numéro unique, qui permet à un réseau GSM ou UMTS d'identifier un usager. Ce numéro est stocké dans la carte SIM respectivement USIM et n'est pas connu de l'utilisateur. Pour atteindre celui-ci, on va lui fournir un numéro MSISDN.
Pour obtenir le code IMEI du smartphone, on peut se baser sur l'expérience de Get "unique device ID" of a mobile device qui propose son avis sur 3 méthodes différentes.
La solution essayé avec succès sur un WM 5.0 est extraite du groupe microsoft.public.dotnet.framework.compactframework : Phone number and IMEI in C# Options
