Update a Cell with C# and Sheets API v4

Question

Does anyone have a good C# example for updating a cell with the v4 API?

I have the get cell values c# example from the developer website working with Google Sheets API v4. I am trying to modify the example to update a cell with a value of "Tom". I'm stuck on the settings for SpreadSheets.Values.Update.

using Google.Apis.Util.Store;

using System.Collections.Generic;

using System.Threading.Tasks;

namespace GoogleSheetsAPI4_v1console
    {
    class Program
    {
        // If modifying these scopes, delete your previously saved credentials
        // at ~/.credentials/sheets.googleapis.com-dotnet-quickstart.json
        static string[] Scopes = { SheetsService.Scope.Spreadsheet };
        static string ApplicationName = "TestSpreadsheet";

        static void Main(string[] args)
        {
            UserCredential credential;

            using (var stream =
                new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
            {
                string credPath = System.Environment.GetFolderPath(
                    System.Environment.SpecialFolder.Personal);
                credPath = Path.Combine(credPath, ".credentials/sheets.googleapis.com-dotnet-quickstart.json");

                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    Scopes,
                    "user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;
                Console.WriteLine("Credential file saved to: " + credPath);
            }

            // Create Google Sheets API service.
            var service = new SheetsService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });


            // Define request parameters.
            String spreadsheetId = "<<myspreadsheetid>>";
            String range = "Sheet1!D5";  // single cell D5
            String myNewCellValue = "Tom";
            SpreadsheetsResource.ValuesResource.UpdateRequest request = service.Spreadsheets.Values.Update(<<what goes here?>>, spreadsheetId, range);

            // Prints the names and majors of students in a sample spreadsheet:
            // https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
            ValueRange response = request.Execute();
            IList<IList<Object>> values = response.Values;
            Console.WriteLine(values);
        }
    }
}

Here is a working example using a console to write a singe cell. Thank you everyone who assisted !!

        static void Main(string[] args)

                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(

            String spreadsheetId2 = "<my spreadsheet ID>";
            String range2 = "<my page name>!F5";  // update cell F5 
            ValueRange valueRange = new ValueRange();

            var oblist = new List<object>() { "My Cell Text" };
            valueRange.Values = new List<IList<object>> { oblist };

            SpreadsheetsResource.ValuesResource.UpdateRequest update = service.Spreadsheets.Values.Update(valueRange, spreadsheetId2, range2);
            update.ValueInputOption = SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum.RAW;
            UpdateValuesResponse result2 = update.Execute();

            Console.WriteLine("done!");
