Question

总的来说，我遇到了一个问题，我无法从表格中读取数据。我遇到的问题非常简单，我将在Excel电子表格的示例中对其进行描述。

从状态表中获取单元格值，如果此单元格显示＆＃34;未发送＆＃34;或者在这种情况下单元格是空的，我从另一个单元格中获取同一行中的数据并开始使用这些数据。成功完成任务后，我设置状态＆＃34;发送＆＃34;到接收数据的单元格。这里一切都很简单，但使用API不明白。已经掌握了授权，即使用标准代码我可以将数据写入表中，但无法取悦，编辑代码。这是代码：

您可以按照此Google Sheets with C#教程进行操作。它表示您将需要来自两个客户端库的NuGet包。第一个是我们需要验证的当前Google .net client library。第二个是我们用来访问Google SpreadSheets的旧版Gdata library。您也可以参考此SO帖子：Accessing Google Spreadsheets with C# using Google Data API
