NPOI Excel保护

List<int> array = new List<int>();
 int[] i ={1,2,3}; //指定那些列需要修改，当然剩下的列就是你希望只读的列了
 array.AddRange(i);
for (int i = 0; i < array.Count; i++)
{
  HSSFCellStyle _cellstyle = workbook.CreateCellStyle();
  _cellstyle.IsLocked = false;//解除锁定
  short m=(short)array[i];
  sheet.SetDefaultColumnStyle(m, _cellstyle); 
}

ICellStyle lockStyle = book.CreateCellStyle();
lockStyle.IsLocked = true;

ICellStyle unLockStyle = book.CreateCellStyle();
unLockStyle.IsLocked = false;

dataCell = dataRow.GetCell(materialCodeColIndex);
if (dataCell == null)
{
dataCell = dataRow.CreateCell(materialCodeColIndex);
dataCell.CellStyle = unLockStyle;
dataRow.Cells.Add(dataCell);
}
else
{
dataCell = dataRow.CreateCell(materialCodeColIndex);
dataCell.CellStyle = unLockStyle;
dataRow.Cells.Add(dataCell);
}

// 把不需要保护的工作表取消保护，然后再保护工作表

dataValidSheet.ProtectSheet("MD5");
