我是新手,有空私聊我。很抱歉这么含糊;代码执行并写入损坏的文件。我无法进入损坏的文件来观察任何错误/异常。大小确实看起来像是要合并的文件的总和。
我已经用谷歌搜索了鼻涕,找不到任何我能理解如何实施的东西。
打开的Word错误是:文件无法打开,因为内容有问题
和
Word 发现无法阅读的内容,您要继续吗?
当我单击“是”时,我再次收到第一个错误,然后我就退出了。
这些文档具有同名的内容控件,但我已将其修改为仅添加 1 个文档,以查看是否存在重复内容类型的问题;相同的损坏文件结果。
顺便说一句....我的最终意图是覆盖“模板”(...Aggregate Report.dotx)。但我无法在任何地方保存有效文件,所以...... :-/
