C # NPOI operating EXCEL- password and read-only settings

Sometimes, we may need to read only certain cells, such as when making a template, the template data is not at liberty to let others changed. In Excel, can "Review -> Protection Sheet" be accomplished, as shown below:

 

 

 

HSSFSheet sheet1 = hssfworkbook.CreateSheet("Sheet1");

sheet1.ProtectSheet ( "password"); // set a password

HSSFRow row1 = sheet1.CreateRow(0); 
HSSFCell cel1 = row1.CreateCell(0); 
HSSFCell cel2 = row1.CreateCell(1); 

HSSFCellStyle unlocked = hssfworkbook.CreateCellStyle(); 
unlocked.IsLocked = false; 

HSSFCellStyle locked = hssfworkbook.CreateCellStyle(); 
locked.IsLocked = true; 

cel1.SetCellValue("没被锁定"); 
cel1.CellStyle = unlocked; 

cel2.SetCellValue("被锁定"); 
cel2.CellStyle = locked; 

As seen in the code, we pass the set ISLocked CellStype is True, it indicates that the cell will be locked. Equivalent of the following operations performed in Excel:

 

 

 Execution results are as follows:

Not locked column can be modified.

 

Locked click Edit will prompt:

 

 

We need to enter a password before they can (where password is the password we set above)
