c# - 在 Google Sheet c# 中创建一个新工作表

Question

我可以使用以下代码检索和更新 Google 表格中的值:

private void btnUpdate_Click(object sender, EventArgs e)
        {
            if (cbYards.Text == "Select Yard")
            {
                MessageBox.Show(@"Please select a yard.");
                return;
            }
            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);
            }

            var service = new SheetsService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            IList<IList<Object>> list = new List<IList<Object>>() { };
            for (var i = 0; i < dataGridView1.Rows.Count - 1; i++)
            {
                var formula = "=IFERROR(VLOOKUP(B"+(i+2)+",Names!$A$2:$B,2,FALSE),\"No Record\")";
                List<object> lists = new List<object>() { formula, dataGridView1.Rows[i].Cells[0].Value.ToString(), 
                    dataGridView1.Rows[i].Cells[1].Value.ToString() };
                list.Add(lists);
            }

            var range = cbYards.Text+"!A2:C";
            ValueRange VRange = new ValueRange();
            VRange.Range = range;
            VRange.Values = list;

            //ValueRange response = request.Execute();
            ValueRange valueRange = new ValueRange();
            valueRange.MajorDimension = "COLUMNS"; 

            SpreadsheetsResource.ValuesResource.UpdateRequest upd = service.Spreadsheets.Values.Update(VRange, spreadsheetId, range);
            upd.ValueInputOption = SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum.USERENTERED;
            UpdateValuesResponse response = upd.Execute();
        }

我的问题是如何在我当前使用的 Google 表格中创建新表格。我以为我需要做的就是更换

SpreadsheetsResource.ValuesResource.UpdateRequest upd = service.Spreadsheets.Values.Update(VRange, spreadsheetId, range);

到

SpreadsheetsResource.ValuesResource.UpdateRequest upd = service.Spreadsheets.create();

但显然这是错误的...

我不明白如何执行 Method: spreadsheets.create 文档中的说明

JSon 与我将如何使用 C# 进行编码有什么关系？非常感谢您的帮助。

更新我在这里找到了这个，但它并不完整，因为它仍然给我一个错误

这是更新后的代码:

private void button1_Click(object sender, EventArgs e)
        {
            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);
            }

            var service = new SheetsService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            string sheetName = string.Format("{0} - {1}-{2}", cbYards.Text, fromDate.Value.ToShortDateString(), toDate.Value.ToShortDateString());
            var myNewSheet = new Google.Apis.Sheets.v4.Data.Spreadsheet();
            myNewSheet.Properties = new SpreadsheetProperties();
            myNewSheet.Properties.Title = sheetName;
            var newSheet = service.Spreadsheets.Create(myNewSheet).Execute();
        }

Answer 1

客户端库中有一个创建方法，您只需将新的工作表对象传递给它即可。不要忘记在分配标题之前实例化属性(下面的第 2 行)

var myNewSheet = new Google.Apis.Sheets.v4.Data.Spreadsheet();
myNewSheet.Properties = new SpreadsheetProperties();
myNewSheet.Properties.Title = "Daimtos awsom sheet";
var awsomNewSheet= service.Spreadsheets.Create(myNewSheet).Execute();
