我正在尝试使用EPPlus为XLSM文件设置工作表权限,但似乎我只能设置默认保护级别,未设置单个保护。为了记录,我正在尝试在this article中以编程方式完成方法1。这是我正在使用的代码:
using (var p = new ExcelPackage("output.xlsm"))
{
var ws = p.Workbook.Worksheets["MySheet"];
// Set some cell values here
// Filtering, sorting, protection
ws.Cells[7, 1, 10, 5].AutoFilter = true;
ws.View.FreezePanes(7, 1);
ws.ProtectedRanges.Add("FilteredCells", new ExcelAddress(7, 1, 10, 5));
// Worksheet protection
ws.Protection.AllowAutoFilter = true;
ws.Protection.AllowDeleteColumns = false;
ws.Protection.AllowDeleteRows = false;
ws.Protection.AllowEditObject = false;
ws.Protection.AllowEditScenarios = false;
ws.Protection.AllowFormatCells = false;
ws.Protection.AllowFormatColumns = false;
ws.Protection.AllowFormatRows = false;
ws.Protection.AllowInsertColumns = false;
ws.Protection.AllowInsertHyperlinks = false;
ws.Protection.AllowInsertRows = false;
ws.Protection.AllowPivotTables = false;
ws.Protection.AllowSelectLockedCells = false;
ws.Protection.AllowSelectUnlockedCells = true;
ws.Protection.AllowSort = true;
ws.Protection.IsProtected = true;
ws.Protection.SetPassword("hunter2");
p.SaveAs(new FileInfo("output.xlsm"));
}
这样运行没有错误,但是当我在Excel中打开文件或将其加载回EPPlus时,我发现已经应用了不同的保护选项:
AllowAutoFilter = false
AllowDeleteColumns = false
AllowDeleteRows = false
AllowEditObject = true
AllowEditScenarios = true
AllowFormatCells = false
AllowFormatColumns = false
AllowFormatRows = false
AllowInsertColumns = false
AllowInsertHyperlinks = false
AllowInsertRows = false
AllowPivotTables = false
AllowSelectLockedCells = true
AllowSelectUnlockedCells = true
AllowSort = false
IsProtected = true
这些显然不是我之前设置的权限,所以如何确保它们设置正确?其他一切都得到了妥善保存。

设置IsProtected
属性会覆盖您的选择:
public bool IsProtected
{
get
{
return GetXmlNodeBool(_isProtectedPath, false);
}
set
{
SetXmlNodeBool(_isProtectedPath, value, false);
if (value)
{
AllowEditObject = true;
AllowEditScenarios = true;
}
else
{
DeleteAllNode(_isProtectedPath); //delete the whole sheetprotection node
}
}
}
将您的IsProtected = true
电话移至您想要的代码或句柄的开头,但您无意中覆盖了之前的选择。我会查看该链接的属性,看看哪些将覆盖您现有的选择。
