Answer 1

Open XML SDK不会限制您生成有效的文档。但是，您可以使用OpenXmlValidator类来报告生成的文档中的任何错误。见this，这是一个很好的例子。

Answer 2

在我的具体情况下，由于工作表名称太长，我遇到了这个问题。这是发生在我身上的事情：

• 在我的程序的第一次运行中，我试图创建带有真正大名的工作表。
• Excel自动将大名字裁剪为31个字符。没有例外被抛出。也就是说，我以为我保存了原来的大名，但我实际上是保存了31个字符长的裁剪字符串。
• 在我的程序的第二次运行中，我正在检查这个特定的工作表是否已经存在，但我认为它不存在，因为现有的工作表已被裁剪。
• 我再次保存工作表。没有例外抛出，但是，新的也被裁剪，现在XML包含2个相同工作表的定义。
• 这会导致Excel尝试修复生成的电子表格。即使它正常工作，我认为它只是扔掉第二个，并使用第一个，这不是我想要的。

我通过在所有的比较之前预先裁剪了31个字符来解决了这个问题。现在它很完美

Answer 3

我很早就知道这个问题，我认为我的经验将解决某人的问题。所以我在这里张贴我的答案。

我有一个类似的问题。它发生在没有。纸张名称中的字符数超过限制31.纸张名称字符必须为< = 31.

创建时不会引发任何异常，但在Microsoft Excel中打开时会出现错误。
