c# - display dynamic keys and values from json into xaml -


below json

{"hello":[{"companyname":"one","eta":"10","invoice":{"tf1":" 49","bf1":" 49","md1":"2 km","fpk1":" 12","att":"1 mins"},"tf3":"49"},{"companyname":"one","eta":"10","invoice":{"tf1":" 49","bf1":" 49","md1":"2 km","fpk1":" 15","att":"1 mins"},"tf3":"49"}],"childpresent":true}

i deserialising , main problem invoice object ( "invoice":{"tf1":" 49","bf1":" 49","md1":"2 km","fpk1":" 15","att":"1 mins"},"tf3":"49"}] ) contains bunch of keys , values...the problem keys inside "invoice" object changes after every 6 hours...and need display both keys , values in xaml

right deserialising above json modal , storing invoice object data dictionary 

rootobject j = jsonconvert.deserializeobject<rootobject>(json);  public class hello  {      public dictionary<string, string> invoice { get; set; }     public string companyname {get;set;}     public string eta {get;set;} }  public class rootobject {      public list<hello> hello { get; set; }     public bool childpresent { get; set; } }

when write in xaml {binding invoice[tf1]} value of tf1 want key tf1 displayed in xaml.

my xaml code
