我在 excel 中创建了一个空模板。我想打开模板并编辑文档，但我不知道如何更改现有工作表。那是代码：


using (SpreadsheetDocument xl = SpreadsheetDocument.Open(filename, true)) 
{ 
WorkbookPart wbp = xl.WorkbookPart; 
WorkbookPart workbook = xl.WorkbookPart; 
// Get the worksheet with the required name. 
// To be used to match the ID for the required sheet data 
// because the Sheet class and the SheetData class aren't 
// linked to each other directly. 
Sheet s = null; 
if (wbp.Workbook.Sheets.Elements().Count(nm => nm.Name == sheetName) == 0) 
{ 
// no such sheet with that name 
xl.Close(); 
return; 
} 
else 
{ 
s = (Sheet)wbp.Workbook.Sheets.Elements().Where(nm => nm.Name == sheetName).First(); 
} 



WorksheetPart wsp = (WorksheetPart)xl.WorkbookPart.GetPartById(s.Id.Value); 
Worksheet worksheet = new Worksheet(); 
SheetData sd = new SheetData(); 
//SheetData sd = (SheetData)wsp.Worksheet.GetFirstChild(); 
Stylesheet styleSheet = workbook.WorkbookStylesPart.Stylesheet; 
//SheetData sheetData = new SheetData(); 
//build the formatted header style 
UInt32Value headerFontIndex = 
util.CreateFont( 
styleSheet, 
"Arial", 
10, 
true, 
System.Drawing.Color.Red); 



//build the formatted date style 
UInt32Value dateFontIndex = 
util.CreateFont( 
styleSheet, 
"Arial", 
8, 
true, 
System.Drawing.Color.Black); 



//set the background color style 
UInt32Value headerFillIndex = 
util.CreateFill( 
styleSheet, 
System.Drawing.Color.Black); 



//create the cell style by combining font/background 
UInt32Value headerStyleIndex = 
util.CreateCellFormat( 
styleSheet, 
headerFontIndex, 
headerFillIndex, 
null); 
/* 
* Create a set of basic cell styles for specific formats... 
* If you are controlling your table then you can simply create the styles you need, 
* this set of code is still intended to be generic. 
*/ 
_numberStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(3)); 
_doubleStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(4)); 
_dateStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(14)); 
_textStyleId = util.CreateCellFormat(styleSheet, headerFontIndex, headerFillIndex, null); 
_percentageStyleId = util.CreateCellFormat(styleSheet, null, null, UInt32Value.FromUInt32(9)); 



util.AddNumber(xl, sheetName, (UInt32)3, "E", "27", _numberStyleId); 
util.AddNumber(xl, sheetName, (UInt32)3, "F", "3.6", _doubleStyleId); 
util.AddNumber(xl, sheetName, (UInt32)5, "L", "5", _percentageStyleId); 
util.AddText(xl, sheetName, (UInt32)5, "M", "Dario", _textStyleId); 
util.AddDate(xl, sheetName, (UInt32)3, "J", DateTime.Now, _dateStyleId); 
util.AddImage(xl, sheetName, imagePath, "Smile", "Smile", 30, 30); 
util.MergeCells(xl, sheetName, "D12", "F12"); 
//util.DeleteValueCell(spreadsheet, sheetName, "F", (UInt32)8); 



txtCellText.Text = util.GetCellValue(xl, sheetName, (UInt32)5, "M"); 



double number = util.GetCellDoubleValue(xl, sheetName, (UInt32)3, "E"); 
double numberD = util.GetCellDoubleValue(xl, sheetName, (UInt32)3, "F"); 
DateTime datee = util.GetCellDateTimeValue(xl, sheetName, (UInt32)3, "J"); 



//txtDoubleCell.Text = util.GetCellValue(spreadsheet, sheetName, (UInt32)3, "P"); 
txtPercentualeCell.Text = util.GetCellValue(xl, sheetName, (UInt32)5, "L"); 



string date = util.GetCellValue(xl, sheetName, (UInt32)3, "J"); 
double dateD = Convert.ToDouble(date); 
DateTime dateTime = DateTime.FromOADate(dateD); 
txtDateCell.Text = dateTime.ToShortDateString(); 



//worksheet.Append(sd); 
/* 
Columns columns = new Columns(); 
columns.Append(util.CreateColumnData(10, 10, 40)); 



worksheet.Append(columns); 
*/ 
SheetProtection sheetProtection1 = new SheetProtection() { Sheet = true, Objects = true, Scenarios = true, SelectLockedCells = true, SelectUnlockedCells = true }; 
worksheet.Append(sheetProtection1); 
wsp.Worksheet = worksheet; 
wsp.Worksheet.Save(); 



xl.WorkbookPart.Workbook.Save(); 
xl.Close();
谢谢！

更新

我尝试了它，但它不起作用。我正在使用这种方法（GetWorksheetPart()），但我想获取现有的工作表，对其进行编辑并保存修改后的新文档。


using (SpreadsheetDocument xl = SpreadsheetDocument.Open(filename, true))
{
     WorkbookPart wbp = xl.WorkbookPart;


 WorksheetPart worksheetPart = util.GetWorksheetPart(wbp, sheetName);
 SheetProtection sheetProtection1 = new SheetProtection() { Sheet = true, Objects = true, Scenarios = true, SelectLockedCells = true, SelectUnlockedCells = true };

 worksheetPart.Worksheet.Append(sheetProtection1);
 worksheetPart.Worksheet.Save(); </pre></code>

我构建了文档但已损坏。为什么？

To get an existing worksheet to edit use this code to get the part:

        public static WorksheetPart GetWorksheetPart(WorkbookPart workbookPart, string sheetName)
        {
            string relId = workbookPart.Workbook.Descendants<Sheet>()
                                 .Where(s => sheetName.Equals(s.Name))
                                 .First()
                                 .Id;

            return (WorksheetPart)workbookPart.GetPartById(relId);
        }

Just make sure that the sheetname exists you are searching for or you will get some exceptions. Then use the reference to that worksheetpart to perform any edits your want and at the end just call worksheetPart.Worksheet.Save();

EDIT

The SheetProtection element needs to be inserted after the SheetData element. Try this line when appending: worksheetPart.Worksheet.Descendants<SheetData>().First().InsertAfterSelf(sheetProtection1);
