如何在使用 C# 将 excel 转换为 Google 工作表时复制样式？

Question

我有一个代码可以将 excel sheet 转换为 google sheet。它正在工作，但仅复制值。

如何将样式和范围（合并的单元格）也复制到 google 表格？

是否还有一种更简单的方法来模拟我打开 google sheets 上的文件？

        foreach (var sheet in wb.Worksheets)
        {
            if (sheet.Index == 0)
            {
                // First sheet is created by default, so only set range
                range = $"{defaultWorksheetName}!A:Y";
            }
            else
            {
                // Add a new sheet
                AddSheet(sheetService, spreadhsheet.SpreadsheetId, sheet.Name);
                range = $"{sheet.Name}!A:Y";
            }

            // Get number of rows and columns
            int rows = sheet.Cells.MaxDataRow;
            int cols = sheet.Cells.MaxDataColumn;

            IList<IList<Object>> list = new List<IList<Object>>() { };

            // Loop through rows
            for (int i = 0; i < rows; i++)
            {
                List<object> lists = new List<object>();

                // Loop through each column in selected row
                for (int j = 0; j < cols; j++)
                {
                    lists.Add(sheet.Cells[i, j].Value);
                }
                list.Add(lists);
            }

            // Define range
            ValueRange VRange = new ValueRange();
            VRange.Range = range;

            // Set values
            VRange.Values = list;

            // Create request
            SpreadsheetsResource.ValuesResource.UpdateRequest upd = sheetService.Spreadsheets.Values.Update(VRange, spreadhsheet.SpreadsheetId, range);
            upd.ValueInputOption = SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum.USERENTERED;

            // Execute request
            UpdateValuesResponse response = upd.Execute();

            // Get response
            string responseString = JsonConvert.SerializeObject(response);

        }

您似乎正在遍历 Excel 行来创建一个对象来手动构建 Google Sheet。查看 Microsoft documentation，您可能还可以阅读这些单元格的格式并使用 Sheets API 来应用它，但是，这个过程似乎太过 time-consuming 和 error-prone.

我的建议是让 Google 为您完成这项工作。驱动器 API 能够 uploading Excel files and converting them to Google Sheets by setting the MimeType to application/vnd.google-apps.spreadsheet. There are some limitations，但通常它能很好地保持单元格格式不变。

Google 的文档不包含 .NET 示例，我不是这方面的专家，但您可以查看他们的 .NET API which does have the Files.create methods, or you could use their REST API。

我发现使用云端硬盘 API 而不是表格 API 并按原样上传文件，然后获取 link 会更好更容易在 Google 张中打开它。

public static string UploadFile(Stream file, string fileName, string fileMime, string fileDescription)
{
    DriveService service = GetService();

    var driveFile = new Google.Apis.Drive.v3.Data.File();
    driveFile.Name = fileName;
    driveFile.Description = fileDescription;
    driveFile.MimeType = "application/vnd.google-apps.spreadsheet";

    var request = service.Files.Create(driveFile, file, driveFile.MimeType);
    request.Fields = "id, webViewLink";

    var response = request.Upload();
    if (response.Status != Google.Apis.Upload.UploadStatus.Completed)
        throw response.Exception;

    return request.ResponseBody.WebViewLink;
}

private static DriveService GetService()
{
    string[] Scopes = { SheetsService.Scope.Drive };
    string ApplicationName = "Excel to Google Sheet";

    UserCredential credential = null;

    using (var stream =
        new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
    {
        string credPath = "token.json";

        var thread = new Thread(() =>
                                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
            GoogleClientSecrets.FromStream(stream).Secrets,
            Scopes,
            "user",
            CancellationToken.None,
            new FileDataStore(credPath, true)).Result)
    
        { IsBackground = false };

        thread.Start();
        if (!thread.Join(20000))
        {
            throw new Exception("Timeout exception..!!!");
        }
        else
        {
            var service = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            return service;
        }
    }
}
