How to add a sheet in google sheets API v4 in C#?

Question

I've been using Google Sheets API, and following The Google Guide. However there is no example, even beyond the second page of google, to add a worksheet and write to a new sheet in .NET. There is plenty for js, but I have no idea on how to 1) add a sheet or 2) write to a new sheet.

How can I do this? Right now I'm able to read like in the example with out any problems, and I've only found one other reference to v4 C#. I tried going back to v3, but all documents strongly suggest using v4.

Has anyone been able to do this? Here's all I've been able to do so far:

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

        // Define request parameters.
        // Add new Sheet
        string sheetName = string.Format("{0} {1}", DateTime.Now.Month, DateTime.Now.Day);
        AddSheetRequest addSheetRequest = new AddSheetRequest();
        addSheetRequest.Properties.Title = sheetName;

        // How do I tell this to update??

To save someone in the future a headache to end all headaches. I figured out how to add a sheet after hours of trial and error. Still working on how to update values.

Here's how I did it:

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

        // Add new Sheet
        string sheetName = string.Format("{0} {1}", DateTime.Now.Month, DateTime.Now.Day);
        var addSheetRequest = new AddSheetRequest();
        addSheetRequest.Properties = new SheetProperties();
        addSheetRequest.Properties.Title = sheetName;
        BatchUpdateSpreadsheetRequest batchUpdateSpreadsheetRequest = new BatchUpdateSpreadsheetRequest();
        batchUpdateSpreadsheetRequest.Requests = new List<Request>();
        batchUpdateSpreadsheetRequest.Requests.Add(new Request
        {
            AddSheet = addSheetRequest
        });

        var batchUpdateRequest =
            service.Spreadsheets.BatchUpdate(batchUpdateSpreadsheetRequest, spreadsheetId);

        batchUpdateRequest.Execute();

I was looking for the Java version of this and I managed to get a working version based on sparky's answer. This should work:

            //Set sheet name
            //Can be any string, I chose to set it to the account name
            String sheetName = mCredential.getSelectedAccountName();

            //Create a new AddSheetRequest
            AddSheetRequest addSheetRequest = new AddSheetRequest();
            SheetProperties sheetProperties = new SheetProperties();

            //Add the sheetName to the sheetProperties
            addSheetRequest.setProperties(sheetProperties);
            addSheetRequest.setProperties(sheetProperties.setTitle(sheetName));

            //Create batchUpdateSpreadsheetRequest
            BatchUpdateSpreadsheetRequest batchUpdateSpreadsheetRequest = new BatchUpdateSpreadsheetRequest();

            //Create requestList and set it on the batchUpdateSpreadsheetRequest
            List<Request> requestsList = new ArrayList<Request>();
            batchUpdateSpreadsheetRequest.setRequests(requestsList);

            //Create a new request with containing the addSheetRequest and add it to the requestList
            Request request = new Request();
            request.setAddSheet(addSheetRequest);
            requestsList.add(request);

            //Add the requestList to the batchUpdateSpreadsheetRequest
            batchUpdateSpreadsheetRequest.setRequests(requestsList);

            //Call the sheets API to execute the batchUpdate
            mService.spreadsheets().batchUpdate(spreadsheetId,batchUpdateSpreadsheetRequest).execute();
