Parse Json Array of Strings to Object C#

try this

var response = new MatchesResponse 
{
  Games = JsonConvert.DeserializeObject<string[]>(responseData);
}

If responseData is a JSON string as in your example, then result can't be a responseData as well. You should rename it to something else in the first place. Simply you can user string[]:

string responsedata = [
"LA1_1200099253",
"LA1_1200030493",
"LA1_1200005581",
"LA1_1199533163",
"LA1_1199521680",
"LA1_1199500161",
"LA1_1199445213",
"LA1_1199385918",
"LA1_1198691674",
"LA1_1198584599",
"LA1_1198580864",
"LA1_1198199891",
"LA1_1198193839",
"LA1_1197677005",
"LA1_1197387180",
"LA1_1197178604",
"LA1_1197195621",
"LA1_1197149865",
"LA1_1197164149",
"LA1_1197050213"
]; 
var result = JsonConvert.DeserializeObject<string[]>(responseData);

foreach(string s in result)
{
   Console.WriteLine(s);
}

deserialize object allows us to parse our c# properties into a json object. if the expressions you define in the array correspond to the object, you can use this method JsonConvert.DeserializeObject<List<"Class Name">>(json);

I had the same problem and this answer helped be to solve it: https://stackoverflow.com/a/48404221/11212251

For your case it would look like this:

[JsonArray]
public class MatchesResponse : ICollection<string>
{
   public ICollection<string> Games { get; }

   public int Count => Games.Count();

   public bool IsReadOnly => Games.IsReadOnly;

   public void Add(string item)
   {
      Games.Add(item);
   }

   public void Clear()
   {
      Games.Clear();
   }

   public bool Contains(string item)
   {
      return Games.Contains(item);
   }

   public void CopyTo(string[] array, int arrayIndex)
   {
      Games.CopyTo(array, arrayIndex);
   }

   public bool Remove(string item)
   {
      return Games.Remove(item);
   }

   public IEnumerator<string> GetEnumerator()
   {
      return Games.GetEnumerator();
   }

   IEnumerator IEnumerable.GetEnumerator()
   {
      return Games.GetEnumerator();
   }
}

var deserializedData = JsonConvert.DeserializeObject<MatchesResponse>(jsonString);
