从名为 SqlCommand 的 C# 将数据附加到 Google 表格答案

【问题标题】：Appending data to a Google Sheet from C# called SqlCommand从名为 SqlCommand 的 C# 将数据附加到 Google 表格
【发布时间】：2018-05-16 15:14:30
【问题描述】：

我从基础开始，学习了如何从我的程序中将固定位的行插入到 Google 表格中，现在我一直在尝试弄清楚如何附加 SQL 的输出。我有一个调用存储过程的 C# 程序，或者它可以执行 select * from table。只需尝试将该选择的结果/输出插入到 Google 表格中。我发现的每个示例都在处理硬编码的固定行和列。我的选择产生少于 2000 行的输出。感谢您的帮助！

【问题讨论】：

考虑将您的问题分解为多个组成部分。你想从 SQL 中获取数据，那应该是它自己的方法。一旦你有了这些数据，你想用它来更新你的谷歌表格，这应该是另一种方法。这将问题分成两个相对容易解决的映射问题。

【解决方案1】：

我能够调整此解决方案以使流程正常运行，而无需向 Google 请求增加配额。它的运行速度不是很快，但可以处理约 1000 条记录。
