在添加数据时打开XML不保存C＃

我从以下链接做了一个完整的副本： https : //msdn.microsoft.com/en-us/library/dd452407(v=office.12).aspx

从模板复制工作正常， FixChartData()方法正常工作。 但是，输出文件不包含任何数据。 我确实看到contentRow包含通过debugging器的数据，但是当我打开文件时，excel表格没有数据。

非常令人沮丧。 任何帮助，将不胜感激。

大卫，我让你的代码工作正常。 这里是我的控制台应用程序的链接。 。 我把它上传到Github，并稍作修改。 我做了2个改变：

1）我无法从您提供的链接下载样本。 于是我用Excel2016创build了一个空白的空白电子表格，并将其保存在该目录中。

2）Fu​​dge数据丢失，所以我通过自我模拟对象生成了一些样本数据。

电子表格从模板中复制并且您的代码使用fudge数据填充它。 以下是最终的结果：

下载后，您需要创build一个Template和Document子目录。 然后将我的ChartExample.xslx文件放在Template目录中并运行。
