只读或locking特定的单元格或行使用打开XML XML SDK

我正在使用打开xml sdk导出excel。 我得到的Excel文件，并将该文件复制到另一个地方，然后我插入数据的新行。

我应该使该行为只读（或我必须locking）使用打开XML XML SDK ..

怎么做 ？

Answer 1

我已经提到以下链接Excel文件密码保护与Open XML SDK 。

在这里，我给你完整的代码来打开目录中的文件并插入单元格。 在这里我只插入了一个单元格。 你可以插入你想要的。 这里我插入了locking的单元格。 find这个，对你非常有帮助

注意：在这里我提到的代码只是读取现有文件并插入行和单元格，并locking手动插入的单元格

谢谢。
