RestSharp deserialization with 2 arrays

I have a json response that I am trying to deserialize with RestSharp This is how it looks

[{"cname":"APPLICANT NAME","dob":"01-01-1997","gender":"2","msg":"Ok","msgcode":"0"},
{"results":
[{"subjectcode":"214","subject":"SOCIAL STUDIES","grade":"C5"},
{"subjectcode":"302","subject":"ENGLISH LANG","grade":"C5"},
{"subjectcode":"402","subject":"MATHEMATICS(CORE)","grade":"E8"},
{"subjectcode":"517","subject":"INTEGRATED SCIENCE","grade":"D7"},
{"subjectcode":"203","subject":"ECONOMICS","grade":"D7"},
{"subjectcode":"204","subject":"GEOGRAPHY","grade":"B3"},
{"subjectcode":"205","subject":"GOVERNMENT","grade":"C6"},
{"subjectcode":"207","subject":"HISTORY","grade":"B3"}]
}]

I have created these classes to help me serialize

public class Result
{
    public string subjectcode { get; set; }
    public string subject { get; set; }
    public string grade { get; set; }
}

public class StudentDetail
{
    public string cname { get; set; }
    public string dob { get; set; }
    public string gender { get; set; }
    public string msg { get; set; }
    public string msgcode { get; set; }
    public List<Result> results { get; set; }
}

public class VerifyData
{
    public List<StudentDetail> StudentDetails { get; set; }
}

However whenever I try to deserialize with RestSharp

IRestResponse response = client.Execute<VerifyData>(request);

I get the following error message:

{"Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'."}

Any pointers, have searched similar questions but was not able to fix this. Thanks

Json data now is

[{"cname":"APPLICANT NAME","dob":"01-01-1997","gender":"2","msg":"Ok","msgcode":"0",
"results":
[{"subjectcode":"214","subject":"SOCIAL STUDIES","grade":"C5"},
{"subjectcode":"302","subject":"ENGLISH LANG","grade":"C5"},
{"subjectcode":"402","subject":"MATHEMATICS(CORE)","grade":"E8"},
{"subjectcode":"517","subject":"INTEGRATED SCIENCE","grade":"D7"},
{"subjectcode":"203","subject":"ECONOMICS","grade":"D7"},
{"subjectcode":"204","subject":"GEOGRAPHY","grade":"B3"},
{"subjectcode":"205","subject":"GOVERNMENT","grade":"C6"},
{"subjectcode":"207","subject":"HISTORY","grade":"B3"}]
}]

You don't need the extra class VerifyData. That you need is the following:

var studentDetails = client.Execute<StudentDetail>(request).Data;

or in two steps:

var response = client.Execute<StudentDetail>(request);
var studentDetails = response.Data;

UPDATE

Using JsonConvert (Json.NET), if you defined the following classes:

public class Result
{
    [JsonProperty("subjectcode")]
    public string Subjectcode { get; set; }

    [JsonProperty("subject")]
    public string Subject { get; set; }

    [JsonProperty("grade")]
    public string Grade { get; set; }
}

public class StudentDetail
{
    [JsonProperty("cname")]
    public string Cname { get; set; }

    [JsonProperty("dob")]
    public string Dob { get; set; }

    [JsonProperty("gender")]
    public string Gender { get; set; }

    [JsonProperty("msg")]
    public string Msg { get; set; }

    [JsonProperty("msgcode")]
    public string Msgcode { get; set; }

    [JsonProperty("results")]
    public IList<Result> Results { get; set; }
}

You can try the following one:

JsonConvert.Deserialize<StudentDetail>(json)
