c# - deserialize json object does not work -


i want deserialize json object student class

var result = jsonconvert.deserializeobject<student>(data);

my json data

{   "student":{     "fname":"997544",   "lname":"997544",   "subject":"it",   "grade":"f" } }

my student class

[serializable] public class student {     [jsonproperty("fname")]     public string firstname{ get; set; }     [jsonproperty("lname")]     public string lastname{ get; set; }     [jsonproperty("subject")]     public string subject { get; set; }     [jsonproperty("grade")]     public string grade { get; set; }  }

the code not work, error says:

cannot deserialize current json object (e.g. {"name":"value"}) type because type requires json array (e.g. [1,2,3]) deserialize correctly.

if have use downloaded json need create model class it

[serializable] public class student {     [jsonproperty("fname")]     public string firstname{ get; set; }     [jsonproperty("lname")]     public string lastname{ get; set; }     [jsonproperty("subject")]     public string subject { get; set; }     [jsonproperty("grade")]     public string grade { get; set; } }  [serializable] public class newmodel {     public student student { get; set; } }

then deserialize

var result = jsonconvert.deserializeobject<newmodel>(data);
