使用EPPlus只读取列或单元格
有没有办法使一列或一组单元格locking或只能使用EPPlus读取？ 我已经尝试了下面的代码单独和一起，但都似乎没有预期的效果。 整个工作表都被locking（如果我包含IsProtected语句）或者什么也不是。
ws.Protection.IsProtected = true; ws.Column(10).Style.Locked = true;

这里是我的控制器的整个代码块
FileInfo newFile = new FileInfo("C:\\Users\\" + User.Identity.Name + "\\Desktop" + @"\\ZipCodes.xlsx"); ExcelPackage pck = new ExcelPackage(newFile); var ws = pck.Workbook.Worksheets.Add("Query_" + DateTime.Now.ToString()); //Headers ws.Cells["A1"].Value = "ChannelCode"; ws.Cells["B1"].Value = "DrmTerrDesc"; ws.Cells["C1"].Value = "IndDistrnId"; ws.Cells["D1"].Value = "StateCode"; ws.Cells["E1"].Value = "ZipCode"; ws.Cells["F1"].Value = "EndDate"; ws.Cells["G1"].Value = "EffectiveDate"; ws.Cells["H1"].Value = "LastUpdateId"; ws.Cells["J1"].Value = "ErrorCodes"; ws.Cells["K1"].Value = "Status"; ws.Cells["I1"].Value = "Id"; //Content int i = 2; foreach (var zip in results) { ws.Cells["A" + i.ToString()].Value = zip.ChannelCode; ws.Cells["B" + i.ToString()].Value = zip.DrmTerrDesc; ws.Cells["C" + i.ToString()].Value = zip.IndDistrnId; ws.Cells["D" + i.ToString()].Value = zip.StateCode; ws.Cells["E" + i.ToString()].Value = zip.ZipCode; ws.Cells["F" + i.ToString()].Value = zip.EndDate.ToShortDateString(); ws.Cells["G" + i.ToString()].Value = zip.EffectiveDate.ToShortDateString(); ws.Cells["H" + i.ToString()].Value = zip.LastUpdateId; ws.Cells["J" + i.ToString()].Value = zip.ErrorCodes; ws.Cells["K" + i.ToString()].Value = zip.Status; ws.Cells["I" + i.ToString()].Value = zip.Id; i++; } //ws.Protection.IsProtected = true; ws.Column(10).Style.Locked = true; return new ExcelResult { FileName = "ZipCodes.xlsx", Package = pck };
ExcelResult
public class ExcelResult : ActionResult { public string FileName { get; set; } public ExcelPackage Package { get; set; } public override void ExecuteResult(ControllerContext context) { context.HttpContext.Response.Buffer = true; context.HttpContext.Response.Clear(); context.HttpContext.Response.AddHeader("content-disposition", "attachment; filename=" + FileName); context.HttpContext.Response.ContentType = "application/vnd.ms-excel"; context.HttpContext.Response.BinaryWrite(Package.GetAsByteArray()); } }
第二编辑
我试图通过将IsProtected值设置为true来保护工作表，然后将Locked属性设置为除最后一列以外的每列。 电子表格不仅处于只读模式，而且可以编辑每列中的数据。
我注意到，但是我不能自己调整实际的列，所以也许这就是我正在做的事情。 我想locking列中的每个单元格，但是，不能input新的数据。
for (int a = 1; a < 10; a++) { ws.Column(a).Style.Locked = false; } ws.Protection.IsProtected = true;
EPPlus可能会默认所有单元格被locking，在这种情况下，您需要为其他列设置Locked属性为false ，然后将IsProtected设置为true 。
我添加了两个WorkSheet，需要保护除第三个索引之外的所有列。
这对我工作:)
worksheet2.Cells["A1"].LoadFromDataTable(dt_Data, true); //------load data from datatable worksheet2.Protection.IsProtected = true; //--------Protect whole sheet worksheet2.Column(3).Style.Locked = false; //-------Unlock 3rd column
只是以为我会张贴的解决scheme，以防别人帮助其他人。 我必须将整个工作表设置为受保护状态，但将每个非Id字段的Locked属性设置为false。
//Content int i = 2; foreach (var zip in results) { //Set cell values ws.Cells["A" + i.ToString()].Value = zip.ChannelCode; ws.Cells["B" + i.ToString()].Value = zip.DrmTerrDesc; ws.Cells["C" + i.ToString()].Value = zip.IndDistrnId; ws.Cells["D" + i.ToString()].Value = zip.StateCode; ws.Cells["E" + i.ToString()].Value = zip.ZipCode; ws.Cells["F" + i.ToString()].Value = zip.EndDate.ToShortDateString(); ws.Cells["G" + i.ToString()].Value = zip.EffectiveDate.ToShortDateString(); ws.Cells["H" + i.ToString()].Value = zip.LastUpdateId; ws.Cells["I" + i.ToString()].Value = zip.ErrorCodes; ws.Cells["J" + i.ToString()].Value = zip.Status; ws.Cells["K" + i.ToString()].Value = zip.Id; //Unlock non-Id fields ws.Cells["A" + i.ToString()].Style.Locked = false; ws.Cells["B" + i.ToString()].Style.Locked = false; ws.Cells["C" + i.ToString()].Style.Locked = false; ws.Cells["D" + i.ToString()].Style.Locked = false; ws.Cells["E" + i.ToString()].Style.Locked = false; ws.Cells["F" + i.ToString()].Style.Locked = false; ws.Cells["G" + i.ToString()].Style.Locked = false; ws.Cells["H" + i.ToString()].Style.Locked = false; ws.Cells["I" + i.ToString()].Style.Locked = false; ws.Cells["J" + i.ToString()].Style.Locked = false; i++; } //Since we have to make the whole sheet protected and unlock each cell //to allow for editing this loop is necessary for (int a = 65000 - i; i < 65000; i++) { //Unlock non-Id fields ws.Cells["A" + i.ToString()].Style.Locked = false; ws.Cells["B" + i.ToString()].Style.Locked = false; ws.Cells["C" + i.ToString()].Style.Locked = false; ws.Cells["D" + i.ToString()].Style.Locked = false; ws.Cells["E" + i.ToString()].Style.Locked = false; ws.Cells["F" + i.ToString()].Style.Locked = false; ws.Cells["G" + i.ToString()].Style.Locked = false; ws.Cells["H" + i.ToString()].Style.Locked = false; ws.Cells["I" + i.ToString()].Style.Locked = false; ws.Cells["J" + i.ToString()].Style.Locked = false; } //Set worksheet protection attributes ws.Protection.AllowInsertRows = true; ws.Protection.AllowSort = true; ws.Protection.AllowSelectUnlockedCells = true; ws.Protection.AllowAutoFilter = true; ws.Protection.AllowInsertRows = true; ws.Protection.IsProtected = true;
ws.Column(10).Style.Locked = true;
应该这样做。 请检查你的代码的其余部分是否有错误:)
所以我指的是这个问题，这就是我如何locking。
worksheet.Protection.IsProtected = true; //I'm creating a template for users to fill in data.These headers //will come from database tables later on. //So tableHeaders is an array of strings for (int i = 1; i <= tableHeaders.Length; i++) { worksheet.Column(i).Style.Locked = false; } //And then lock the first row. worksheet.Row(1).Style.Locked = true; //Additionally don't allow user to change sheet names excelPackage.Workbook.Protection.LockStructure = true;
首先locking整个工作表，然后解锁你想解锁的单元格。
workSheet.Protection.IsProtected = true; workSheet.Cells[2, 3, pocDeatils.CityMaster.Rows.Count + 1, 4].Style.Locked = false;
