如何在 C# 中获取用户输入并更新 Google 电子表格

Question

我有一个 Google 电子表格，用作文具室的库存清单。这在 c# 中被证明是一个具有挑战性的构建，因为我需要让用户输入他们想要多少支笔并更新电子表格中的 qty 字段。我可以通过硬编码来做到这一点，但是如何更改它以获取用户输入。

我创建了一个可重用的函数，它接受一个以竖线分隔的字符串并将其逐行写入指定的工作表中。我在 DLL 中执行此操作，因此我通常避免从控制台读取/写入。

private string GoogleSheetsUpdate(string fileId, string inputOption, string inputRange, string inputText) {
        //PURPOSE: SETS VALUES IN A RANGE OF A SPREADSHEET.
        //REFERENCE: https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/update
        string result = "Success";
        try {
            //HOW THE INPUT DATA SHOULD BE INTERPRETED:
            //THE VALUES WILL BE PARSED AS IF THE USER TYPED THEM INTO THE UI. NUMBERS WILL STAY AS NUMBERS, BUT STRINGS MAY BE CONVERTED
            //TO NUMBERS, DATES, ETC.FOLLOWING THE SAME RULES THAT ARE APPLIED WHEN ENTERING TEXT INTO A CELL VIA THE GOOGLE SHEETS UI.
            SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum valueInputOption = SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum.USERENTERED;
            inputOption = inputOption.ToLower();
            if (inputOption == "raw") {
                //THE VALUES THE USER HAS ENTERED WILL NOT BE PARSED AND WILL BE STORED AS-IS.
                valueInputOption = SpreadsheetsResource.ValuesResource.UpdateRequest.ValueInputOptionEnum.RAW;
            }

            //ASSIGN VALUES TO DESIRED PROPERTIES OF REQUESTBODY; ALL EXISTING PROPERTIES WILL BE REPLACED
            string[] oRow = inputText.Split('|');
            ValueRange oBody = new ValueRange {
                Values = new List<IList<object>> { oRow },
            };
            SpreadsheetsResource.ValuesResource.UpdateRequest oRequest = sheetsService.Spreadsheets.Values.Update(oBody, fileId, inputRange);
            oRequest.ValueInputOption = valueInputOption;
            UpdateValuesResponse oResponse = oRequest.Execute();
        } catch (Exception e) {
            result = "Google Sheets API: " + e.Message;
        }
        return result;
        //RESPONSE: IF SUCCESSFUL, THE RESPONSE BODY CONTAINS AN INSTANCE OF UPDATEVALUESRESPONSE.
    }
