我试图将不同的数据放入同一工作簿中的不同工作表中，并且每个工作表具有不同的页面设置（例如页眉，页脚等）。
当我执行程序时，数据可以成功显示在不同的工作表中，但是当我检查打印预览时页面设置无法正常工作（例如缺少页眉和页脚），有人知道原因吗？
bellow是按钮单击事件：
private void btnExportAllToExcel_Click(object sender, EventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel Documents (*.xls)|*.xls";
sfd.FileName = "StockReport(ALL)_" + DateTime.Now.ToString("ddMMyyyy HHmmss") + ".xls";
if (sfd.ShowDialog() == DialogResult.OK)
{
Cursor = Cursors.WaitCursor; // change cursor to hourglass type
object misValue = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Excel.Application xlexcel = new Microsoft.Office.Interop.Excel.Application();
xlexcel.PrintCommunication = false;
xlexcel.ScreenUpdating = false;
xlexcel.DisplayAlerts = false; // Without this you will get two confirm overwrite prompts
Workbook xlWorkBook = xlexcel.Workbooks.Add(misValue);
saveDataToSheet(xlWorkBook);
xlexcel.Calculation = XlCalculation.xlCalculationManual;
//Save the excel file under the captured location from the SaveFileDialog
xlWorkBook.SaveAs(sfd.FileName, XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlexcel.DisplayAlerts = true;
xlWorkBook.Close(true, misValue, misValue);
xlexcel.Quit();
releaseObject(xlWorkBook);
releaseObject(xlexcel);
// Clear Clipboard and DataGridView selection
Clipboard.Clear();
dgvStockReport.ClearSelection();
// Open the newly saved excel file
if (File.Exists(sfd.FileName))
System.Diagnostics.Process.Start(sfd.FileName);
}
}
bellow是用于将数据从datagridview复制到工作表方法的代码，我认为问题就在这里，但我找不到它：
//copy data from datagridview to clipboard and paste to excel sheet
private void saveDataToSheet(Workbook xlWorkBook)
{
int sheetNo = 1;
Worksheet xlWorkSheet = null;
bool gotData = false;
//load different data list to datagridview by changing the comboBox selected index
for (int i = 0; i <= cmbType.Items.Count - 1; i++)
{
cmbType.SelectedIndex = i;
for (int j = 0; j <= cmbSubType.Items.Count - 1; j++)
{
cmbSubType.SelectedIndex = j;
if (cmbType.Text.Equals(CMBPartHeader))
{
gotData = loadPartStockData();//if data != empty return true, else false
}
else if (cmbType.Text.Equals(CMBMaterialHeader))
{
gotData = loadMaterialStockData();//if data != empty return true, else false
}
if(gotData)//if datagridview have data
{
copyAlltoClipboard();//select all from datagridview and copy to clipboard
//create new sheet
var xlSheets = xlWorkBook.Sheets as Sheets;
var xlNewSheet = (Worksheet)xlSheets.Add(xlSheets[sheetNo], Type.Missing, Type.Missing, Type.Missing);
xlWorkSheet = xlNewSheet;
xlWorkSheet = (Worksheet)xlWorkBook.Worksheets.get_Item(sheetNo);
xlWorkSheet.Name = cmbSubType.Text;
//Header and Footer setup
xlWorkSheet.PageSetup.LeftHeader = "&\"Calibri,Bold\"&11 " + DateTime.Now.Date.ToString("dd/MM/yyyy"); ;
xlWorkSheet.PageSetup.CenterHeader = "&\"Calibri,Bold\"&16 (" + cmbSubType.Text + ") Stock List";
xlWorkSheet.PageSetup.RightHeader = "&\"Calibri,Bold\"&11 PG -&P";
xlWorkSheet.PageSetup.CenterFooter = "Printed By " + dalUser.getUsername(MainDashboard.USER_ID);
//Page setup
xlWorkSheet.PageSetup.PaperSize = XlPaperSize.xlPaperA4;
xlWorkSheet.PageSetup.Orientation = XlPageOrientation.xlPortrait;
xlWorkSheet.PageSetup.Zoom = false;
xlWorkSheet.PageSetup.CenterHorizontally = true;
xlWorkSheet.PageSetup.LeftMargin = 1;
xlWorkSheet.PageSetup.RightMargin = 1;
xlWorkSheet.PageSetup.FitToPagesWide = 1;
xlWorkSheet.PageSetup.FitToPagesTall = false;
xlWorkSheet.PageSetup.PrintTitleRows = "$1:$1";
// Paste clipboard results to worksheet range
xlWorkSheet.Select();
Range CR = (Range)xlWorkSheet.Cells[1, 1];
CR.Select();
xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);
//content edit
Range tRange = xlWorkSheet.UsedRange;
tRange.Borders.LineStyle = XlLineStyle.xlContinuous;
tRange.Borders.Weight = XlBorderWeight.xlThin;
tRange.Font.Size = 11;
tRange.EntireColumn.AutoFit();
tRange.Rows[1].interior.color = Color.FromArgb(237, 237, 237);//change first row back color to light grey
sheetNo++;
// Clear Clipboard and DataGridView selection
Clipboard.Clear();
dgvStockReport.ClearSelection();
releaseObject(xlWorkSheet);
}
}
}
}
我是新来的，也正在编码，所以如果我做错了，请告诉我，非常感谢^^
答案 0 :(得分：0)
在线研究并修改我的代码大约4个小时后，现在可以正常工作！
我尝试先保存工作簿， 然后将其打开以将数据插入工作表并更改页面设置。
代码：
private void btnExportAllToExcel_Click(object sender, EventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel Documents (*.xls)|*.xls";
sfd.FileName = "StockReport(ALL)_" + DateTime.Now.ToString("ddMMyyyy_HHmmss") + ".xls";
if (sfd.ShowDialog() == DialogResult.OK)
{
string path = Path.GetFullPath(sfd.FileName);
Cursor = Cursors.WaitCursor; // change cursor to hourglass type
object misValue = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Excel.Application xlexcel = new Microsoft.Office.Interop.Excel.Application();
xlexcel.PrintCommunication = false;
xlexcel.ScreenUpdating = false;
xlexcel.DisplayAlerts = false; // Without this you will get two confirm overwrite prompts
Workbook xlWorkBook = xlexcel.Workbooks.Add(misValue);
//Save the excel file under the captured location from the SaveFileDialog
xlWorkBook.SaveAs(sfd.FileName,
XlFileFormat.xlWorkbookNormal,
misValue, misValue, misValue, misValue,
XlSaveAsAccessMode.xlExclusive,
misValue, misValue, misValue, misValue, misValue);
insertDataToSheet(path,sfd.FileName);
xlexcel.DisplayAlerts = true;
xlWorkBook.Close(true, misValue, misValue);
xlexcel.Quit();
releaseObject(xlWorkBook);
releaseObject(xlexcel);
// Clear Clipboard and DataGridView selection
Clipboard.Clear();
dgvStockReport.ClearSelection();
}
}
以下是将数据插入工作表方法的代码：
private void insertDataToSheet(string path, string fileName)
{
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
excelApp.Visible = true;
Workbook g_Workbook = excelApp.Workbooks.Open(
path,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
bool gotData = false;
object misValue = System.Reflection.Missing.Value;
//load different data list to datagridview but changing the comboBox selected index
for (int i = 0; i <= cmbType.Items.Count - 1; i++)
{
cmbType.SelectedIndex = i;
for (int j = 0; j <= cmbSubType.Items.Count - 1; j++)
{
cmbSubType.SelectedIndex = j;
if (cmbType.Text.Equals(CMBPartHeader))
{
gotData = loadPartStockData();//if data != empty return true, else false
}
else if (cmbType.Text.Equals(CMBMaterialHeader))
{
gotData = loadMaterialStockData();//if data != empty return true, else false
}
if (gotData)//if datagridview have data
{
Worksheet addedSheet = null;
int count = g_Workbook.Worksheets.Count;
addedSheet = g_Workbook.Worksheets.Add(Type.Missing,
g_Workbook.Worksheets[count], Type.Missing, Type.Missing);
addedSheet.Name = cmbSubType.Text;
addedSheet.PageSetup.LeftHeader = "&\"Calibri,Bold\"&11 " + DateTime.Now.Date.ToString("dd/MM/yyyy"); ;
addedSheet.PageSetup.CenterHeader = "&\"Calibri,Bold\"&16 (" + cmbSubType.Text + ") STOCK LIST";
addedSheet.PageSetup.RightHeader = "&\"Calibri,Bold\"&11 PG -&P";
addedSheet.PageSetup.CenterFooter = "Printed By " + dalUser.getUsername(MainDashboard.USER_ID);
//Page setup
addedSheet.PageSetup.PaperSize = XlPaperSize.xlPaperA4;
addedSheet.PageSetup.Orientation = XlPageOrientation.xlPortrait;
addedSheet.PageSetup.Zoom = false;
addedSheet.PageSetup.CenterHorizontally = true;
addedSheet.PageSetup.LeftMargin = 1;
addedSheet.PageSetup.RightMargin = 1;
addedSheet.PageSetup.FitToPagesWide = 1;
addedSheet.PageSetup.FitToPagesTall = false;
addedSheet.PageSetup.PrintTitleRows = "$1:$1";
copyAlltoClipboard();
addedSheet.Select();
Range CR = (Range)addedSheet.Cells[1, 1];
CR.Select();
addedSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);
Range tRange = addedSheet.UsedRange;
tRange.Borders.LineStyle = XlLineStyle.xlContinuous;
tRange.Borders.Weight = XlBorderWeight.xlThin;
tRange.Font.Size = 11;
tRange.EntireColumn.AutoFit();
tRange.Rows[1].interior.color = Color.FromArgb(237, 237, 237);//change first row back color to light grey
Clipboard.Clear();
dgvStockReport.ClearSelection();
}
}
}
g_Workbook.Worksheets.Item[1].Delete();
g_Workbook.Save();
}
