Bonjour la communauté,
Je fais appel à un Web Service en API Rest et mon code malgré mes recherches me renvoie toujours le message suivant :
J'ai bien rajouté les 2 lignes suivantes :La demande a été abandonnée: impossible de créer le canal sécurisé SSL / TLS
Je poste mon code, si quelqu'un d'entre vous a une idée ?
Code : Sélectionner tout - Visualiser dans une fenêtre à part
1
2ServicePointManager.Expect100Continue = true ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls1
Merci d'avance
