Question

我尝试从30个以上的单元中获取数据（如果我没记错的话，大约是40个），但是一直到30个单元以下。如何解决此问题？

在第9种情况下-好的
第10种情况-失败。

行有30个项目，但我选择了更多

namespace CBox
{
    public partial class Form1 : Form
    {
        static string[] Scopes = { SheetsService.Scope.SpreadsheetsReadonly };
        static string ApplicationName = "CBox";

        static String spreadsheetId = "1LovVHkHGQYADfgEBMGEaZFTDkSgQEQhQ-FuRZHWkXHo";
        String range;
        static String credPath = "token.json";
        static FileStream stream = new FileStream("credentials.json", FileMode.Open, FileAccess.Read);
        SpreadsheetsResource.ValuesResource.GetRequest request;

        static UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.Load(stream).Secrets, Scopes, "user", CancellationToken.None, new FileDataStore(credPath, true)).Result;
        SheetsService service = new SheetsService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = ApplicationName,
        });


        private void ComboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

            comboBox2.Items.Clear();

            range = "A2:AT9";
            request = service.Spreadsheets.Values.Get(spreadsheetId, range);
            //request.MajorDimension = SpreadsheetsResource.ValuesResource.GetRequest.MajorDimensionEnum.COLUMNS;
            ValueRange response = request.Execute();
            IList<IList<Object>> values = response.Values;

            switch (comboBox1.SelectedIndex)
            {
                ***********

                case 9:                                                     //120
                    foreach (var rows in values)
                    {
                        if (rows[28] != "" && rows[29] != "")
                        {
                            comboBox2.Items.Add(rows[0]);
                        }
                    }
                    break;

                case 10:                                                     //130
                    foreach (var rows in values)
                    {
                        if (rows[30] != "" && rows[31] != "")
                        {
                            comboBox2.Items.Add(rows[0]);
                        }
                    }
                    break;


            }
        }
    }
}

Answer 1

您可以检查范围内的所有单元格是否都有值？将返回包含值的单元格的最大范围。因此，如果您在范围末尾输入了一些空值，则不会返回它们。

编辑.. 我试图从您在评论中发布的表格中获取范围，没问题。

{"majorDimension":"ROWS","range":"'????1'!A9:AT9","values":[["Prime Grand 2835 3 Lens","74","15","180","0,72","160","75","Cool White","http://tdkatod.ru/1497","","","","","","100","75","110","80","130","90","140","100","150","115","160","125","170","130","180","140","190","150","200","160","210","170","220","180","230","190","240","220"]],"ETag":null}

您使用哪个API版本？如果您在Google API页面上尝试使用代码（C＃），那么它将正常工作。

Answer 2

Google严格按照内容切割行。

假设您在Google表格中有一个表格：

[dsds] [dwdw] []
[dswg] [] []
[dswf] [] [dwdw]

如果您请求指定范围（A0：C2），然后在调试过程中查看VisualStudio中的值，您会发现每行中没有三个元素，但是恰好需要的数量。不会自动上传任何多余的空单元格。

[dsds] [dwdw]
[dswg]
[dswf] [] [dwdw]

我没有考虑到这一点。我将值与字符串中的索引进行了比较，实际上不存在该索引，尽管从理论上讲该单元格处于请求的范围内。

为什么一张桌子不能容纳30个以上的单元格？
