我正在尝试将数据插入多个工作表。对于我的Excel，我有两张“chart”和“ChartData”。我能够更新sheet2，chartdata表中的数据，但我无法将数据插入到sheet1。这是我试图将数据插入Excel工作表的代码。这里的数据来自数据库。
double ticks = DateTime.Now.Ticks;
// MarketAnalysis ms = new MarketAnalysis();
//ms.Marketanalysis();
File.Copy(Srcpath, @"E:\Works\OpenXML\DownloadTemplates\ExcelGenerated" + ticks + ".xlsx", true);
using (SpreadsheetDocument myworkbok = SpreadsheetDocument.Open(@"E:\Works\OpenXML\DownloadTemplates\ExcelGenerated" + ticks + ".xlsx", true))
{
//Acess the main workbook which contain all the references
WorkbookPart workbookpart = myworkbok.WorkbookPart;
//Get sheet by name
Sheet sheet = workbookpart.Workbook.Descendants<Sheet>().Where(s => s.Name == "ChartData").FirstOrDefault();
//Worksheet Part by ID
WorksheetPart worksheetpart = workbookpart.GetPartById(sheet.Id) as WorksheetPart;
//Sheet data contains all the data
SheetData sheetdata = worksheetpart.Worksheet.GetFirstChild<SheetData>();
DataSet ds = db.Chart1Data();
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
// if (ds.Tables[0].Rows !=DBNull)
//{
string Rowlabel = ds.Tables[0].Rows[i][0].ToString();
// float? FY13Actuval = Convert.ToInt32(ds.Tables[0].Rows[i][1]);
if (!string.IsNullOrEmpty(ds.Tables[0].Rows[i][1].ToString()))
{
// string s = ds.Tables[0].Rows[i][1].ToString();
//FY13Actuval=float.Parse(ds.Tables[0].Rows[i][1].ToString());
FY13Actuval = Convert.ToDouble(ds.Tables[0].Rows[i][1].ToString());
}
else
{
FY13Actuval = null;
}
double? Budget = Convert.ToDouble(ds.Tables[0].Rows[i][2].ToString());
double? Actuval = Convert.ToDouble(ds.Tables[0].Rows[i][3].ToString());
Row contentrow = CreateContentRow(index, Product, Actual, Budget, Forecast);
index++;
sheetdata.AppendChild(contentrow);
// }
}
.......Same code for the other 3 charts
Sheet sheet1 = workbookpart.Workbook.Descendants<Sheet>().Where(s => s.Name == "Charts").FirstOrDefault();
WorksheetPart worksheetpart1 = workbookpart.GetPartById(sheet1.Id) as WorksheetPart;
//Sheet data contains all the data
SheetData sheetdata1 = worksheetpart1.Worksheet.GetFirstChild<SheetData>();
DataSet dsTbl = db.Table();
int SCMTblIndex=5;
for (int i = 0; i < dsTbl.Tables[0].Rows.Count; i++)
{
Row tblRow = CreateScorecardMetricTblRow(SCMTblIndex, dsTbl.Tables[0].Rows[i][0].ToString(),
dsTbl.Tables[0].Rows[i][1].ToString(),
dsTbl.Tables[0].Rows[i][2].ToString());
SCMTblIndex++;
sheetdata1.AppendChild(tblRow);
}
myworkbok.WorkbookPart.Workbook.Save();
}
和创建单元格的方法：
public static string[] headerColumns = new string[]{ "A", "B", "C", "D", "E", "F", "G", "I", "J" };
public static string[] header = new string[] { "D", "E", "F" };
private static Row CreateContentRow(int index, string Product, double? Actual, double? Budget, double? Forecast)
{
//Create New ROw
Row r = new Row();
r.RowIndex = (UInt32)index;
//Begin colums
Cell c0 = new Cell();
c0.CellReference = headerColumns[0] + index;
CellValue v0 = new CellValue();
v0.Text = Product;
c0.AppendChild(v0);
r.AppendChild(c0);
Cell c1 = new Cell();
c1.CellReference = headerColumns[1] + index;
CellValue v1 = new CellValue();
v1.Text = Actual.ToString();
c1.AppendChild(v1);
r.AppendChild(c1);
Cell c2 = new Cell();
c2.CellReference = headerColumns[2] + index;
CellValue v2 = new CellValue();
v2.Text = Budget.ToString();
c2.AppendChild(v2);
r.AppendChild(c2);
Cell c3 = new Cell();
c3.CellReference = headerColumns[3] + index;
CellValue v3 = new CellValue();
v3.Text = Forecast.ToString();
c3.AppendChild(v3);
r.AppendChild(c3);
return r;
}
public static Row CreateScorecardMetricTblRow(int index, string Act_Data, string Bud_Data, string VarPr_Data)
{
Row r = new Row();
r.RowIndex = (UInt32)index;
//Begin Colums
Cell c0 = new Cell();
c0.CellReference = header[0] + index;
CellValue v0 = new CellValue();
v0.Text = Act_Data;
c0.AppendChild(v0);
r.AppendChild(c0);
Cell c1 = new Cell();
c1.CellReference = header[1] + index;
CellValue v1 = new CellValue();
v1.Text = Bud_Data;
c1.AppendChild(v1);
r.AppendChild(c1);
Cell c2 = new Cell();
c2.CellReference = header[2] + index;
CellValue v2 = new CellValue();
v2.Text = VarPr_Data;
c2.AppendChild(v2);
r.AppendChild(c2);
return r;
}
答案 0 :(得分：3)
只需更新
的多张工作表// Open the document for editing.
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(docName, true))
{
// Insert code here.
}
为两个工作表创建两个类，您需要更新工作表单元格值。对于每个类构造函数，传递 SpreadsheetDocument 对象并实现insert text into a cell in a spreadsheet document。只需避免插入新代码表单并尝试仅插入单元格代码。

你可以尝试这种方法.....它可能会有所帮助..
私有静态Cell InsertCellInWorksheet（string columnName，int rowIndex，WorksheetPart worksheetPart） { Worksheet workheet = worksheetPart.Worksheet; SheetData sheetData = worksheet.GetFirstChild（）; string cellReference = columnName + rowIndex;
Alignment alignment1 = new Alignment() { WrapText = true };
// If the worksheet does not contain a row with the specified row index, insert one.
Row row;
row = new Row() { RowIndex = 3, StyleIndex = 1 };
if (sheetData.Elements<Row>().Where(r => r.RowIndex == rowIndex).Count() != 0)
{
row = sheetData.Elements<Row>().Where(r => r.RowIndex == rowIndex).First();
}
else
{
row = new Row() { RowIndex = Convert.ToUInt32(rowIndex) };
sheetData.Append(row);
}
// If there is not a cell with the specified column name, insert one.
if (row.Elements<Cell>().Where(c => c.CellReference.Value == columnName + rowIndex).Count() > 0)
{
Row row2;
row2 = new Row() { RowIndex = 3, StyleIndex = 1 };
Cell rCell = null;
foreach (Cell celld in row.Elements<Cell>())
{
if (string.Compare(celld.CellReference.Value, "A3", true) > 0)
{
rCell = celld;
break;
}
}
// Add the cell to the cell table at A1.
Cell newCell = new Cell() { CellReference = "C3" };
//Cell newCell1 = new Cell() { CellReference = "D3" };
row.InsertBefore(newCell, rCell);
//row.InsertBefore(newCell1, rCell);
// Set the cell value to be a numeric value of 100.
newCell.CellValue = new CellValue("#GUIDeXactLCMS#");
//newCell1.CellValue = new CellValue("EN");
newCell.DataType = new EnumValue<CellValues>(CellValues.Number);
return row.Elements<Cell>().Where(c => c.CellReference.Value == cellReference).First();
}
else
{
// Cells must be in sequential order according to CellReference. Determine where to insert the new cell.
Cell refCell = null;
foreach (Cell cell in row.Elements<Cell>())
{
if (string.Compare(cell.CellReference.Value, cellReference, true) > 0)
{
//string val = cell.CellReference.Value;
refCell = cell;
break;
}
}
Cell newCell = new Cell() { CellReference = cellReference };
row.InsertBefore(newCell, refCell);
return newCell;
}
worksheet.Save();
}
