class wxmessage { public string FromUserName { get ; set ; } public string ToUserName { get ; set ; } public string MsgType { get ; set ; } public string EventName { get ; set ; } public string Content { get ; set ; } public string Recognition { get ; set ; } public string EventKey { get ; set ; } } |
