C＃导出到XLS问题
我打算将数据导出到一个格式化的XLS，但我似乎有某种限制问题。 它导出一些数据集，有些则不。
我浏览了结果的XML并对大部分行进行了评论，然后一个接一个地对它们进行了解，直到文档被打开。 我知道行和列的限制，但导致的文档无法在Excel之前打开。 我说的是超过34个excel行（大约500条格式化的XML行）失败。
这是我的完整的出口代码：

有没有人有一个线索，为什么Excel不会打开这个文件？
ExpandedRowCount是你的问题。 显然它不符合实际的行数。
我删除它，它打开得很好。
更好的select是输出实际的行数。
我不认为这是一个限制，因为我们知道Excel不限于这么less的行数。 这几乎肯定是数据/转义特殊字符的问题…你用AppendLine添加行的方式是不安全的…数据中没有“<”或其他无效的XML字符？
我build议你使用适当的XLS组件，以便解决所有这些问题。有很多免费的，开源的和商业的提供。
