deserialize json array of object c# RIOT API [NOT WORKING] - json

Question

i've recently started to start on a new small project, but have come across some issues.. I'm not really sure why it's not working honestly.
public partial class MatchlistDto
{
public List<MatchHistory> matchhistory { get; set; }
}
public partial class MatchHistory
{
[JsonProperty("platformId")]
public string platformId { get; set; }
[JsonProperty("gameId")]
public long gameId { get; set; }
[JsonProperty("champion")]
public int champion { get; set; }
[JsonProperty("queue")]
public int queue { get; set; }
[JsonProperty("season")]
public int season { get; set; }
[JsonProperty("timestamp")]
public long timestamp { get; set; }
[JsonProperty("role")]
public string role { get; set; }
[JsonProperty("lane")]
public string lane { get; set; }
}
public partial class SummonerV4
{
public string id { get; set; }
public string accountId { get; set; }
public string puuid { get; set; }
public string profileIconId { get; set; }
public string revisionDate { get; set; }
public string summonerLevel { get; set; }
}
Code from Controller.
[HttpPost]
public async Task<ActionResult> DisplayAccount(string Region, string User)
{
string ApiKey = "TottalyAnApiKey";
SummonerV4 UserInfo = new SummonerV4();
using (var client = new HttpClient())
{
HttpResponseMessage Res = await client.GetAsync("https://" + Region + ".api.riotgames.com/lol/summoner/v4/summoners/by-name/"+ User +"?api_key="+ ApiKey);
if (Res.IsSuccessStatusCode)
{
var apiResponse = Res.Content.ReadAsStringAsync().Result; //First part is to get AccountInformation from user. e.g AccountID.
UserInfo = JsonConvert.DeserializeObject<SummonerV4>(apiResponse);
HttpResponseMessage Res2 = await client.GetAsync("https://" + Region + ".api.riotgames.com" + "/lol/match/v4/matchlists/by-account/" + User + "?api_key=" + ApiKey); //Second part is to collect the Match History from user.
if (Res2.IsSuccessStatusCode)
{
var PersonalResponse2 = Res2.Content.ReadAsStringAsync().Result;
List<MatchlistDto> matchHistoryList = JsonConvert.DeserializeObject<List<MatchlistDto>>(PersonalResponse2);
}
}
}
return View(UserInfo);
}
So whats going on is that, i do get the correct response from RiotGames API but i can't really deserialize it correctly. Please check images. My wish is to store the data in a list or array.
Here you can see all the objects from the response
And here the error

Answer 1

A couple problems:
1: MatchlistDto matchhistory field is misnamed
It should look like this:
public partial class MatchlistDto
{
public List<MatchHistory> matches { get; set; }
}
Or like this:
public partial class MatchlistDto
{
[JsonProperty("matches")]
public List<MatchHistory> matchhistory { get; set; }
}
2: API returns a MatchlistDto, not a List
Should write this:
MatchlistDto matchHistoryList = JsonConvert.DeserializeObject<MatchlistDto>(PersonalResponse2);
