只读或使用open xml sdk锁定特定的单元格或行 [英] Read only or Lock the particular cells or rows using open xml sdk

问题描述

我使用open xml sdk来导出excel。我得到的excel文件，并将该文件复制到另一个地方，然后我插入新的行与数据。

I am using open xml sdk to export excel. I get the excel file and copying that file to another place and then I'm inserting new rows with the data.

我应该把这行作为只读（或我使用open xml sdk进行锁定。

I should make that rows as read only (or I've to lock) using open xml sdk..

如何做？

推荐答案

我已经引用了以下链接 Excel文件密码使用Open XML SDK进行保护。

I've referred the following link Excel File Password Protection with Open XML SDK.

这里我给了你完整的代码，从目录打开文件并插入单元格。这里我只插入了一个单元格。您可以根据需要插入。这里我插入了锁定的单元格。找到这个，这对你来说非常有帮助..

Here I gave you full code to open the file from directory and insert cells. Here I've inserted only one cell. You can insert as you want. Here I've inserted locked cells. Find this one, it'll very helpful to you..

注意：这里我只提到了代码只读现有文件并插入行和单元格并锁定手动插入的单元格

谢谢。

// To read the xlsx file..

// create a document
