Save/Close Excel Workbook and quit excel with no popups c#

I have the below code which works to delete the first row of a specified excel workbook. After this is done I would like to save (Overwrite changes) and exit the excel applications.
I gathered this may be achieved by Workbook.Close(True) but the popups still occur and the Object workbook is not referenced.
Any help would be much appreciated.
public void DeleteRows(string workbookPath)
{
// New Excel Application
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
//Open WorkBook
Microsoft.Office.Interop.Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath,
0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "",
true, false, 0, true, false, false);
Microsoft.Office.Interop.Excel.Sheets excelSheets = excelWorkbook.Worksheets;
string currentSheet = "Sheet1";
Microsoft.Office.Interop.Excel.Worksheet excelWorksheet = (Microsoft.Office.Interop.Excel.Worksheet)excelSheets.get_Item(currentSheet);
Microsoft.Office.Interop.Excel.Range excelCell = (Microsoft.Office.Interop.Excel.Range)excelWorksheet.get_Range("A1", "A1");
Microsoft.Office.Interop.Excel.Range row = excelCell.EntireRow;
row.Delete(Microsoft.Office.Interop.Excel.XlDirection.xlUp);
}

Honestly, all I think that's missing from your code is a save and close. Once you save, the warning should not be issued.
using Excelx = Microsoft.Office.Interop.Excel;
public void DeleteRows(string workbookPath)
{
// New Excel Application
Excelx.Application excelApp = new Excelx.Application();
//Open WorkBook
Excelx.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath,
0, false, 5, "", "", false, Excelx.XlPlatform.xlWindows, "",
true, false, 0, true, false, false);
Excelx.Sheets excelSheets = excelWorkbook.Worksheets;
string currentSheet = "Sheet1";
Excelx.Worksheet excelWorksheet = (Excelx.Worksheet)excelSheets.get_Item(currentSheet);
Excelx.Range excelCell = (Excelx.Range)excelWorksheet.get_Range("A1", "A1");
Excelx.Range row = excelCell.EntireRow;
row.Delete(Excelx.XlDirection.xlUp);
// This should be all you need:
excelWorkbook.Save();
excelWorkbook.Close();
}
I'd be puzzled if this doesn't work, but if it doesn't, it might help when you are debugging to make Excel visible and step through the code:
excelApp.Visible = true;
As a final last attempt, before you save, you can disable warnings which will tell Excel to dispense with any of the dialogs to try to save you from yourself:
excelApp.DisplayAlerts = false;
excelWorkbook.Save();
excelWorkbook.Close();
excelApp.DisplayAlerts = true;
And again, I think you shouldn't even get to step 2 for this to work, but let me know if it doesn't. We would have quite a puzzle.

Copy an Excel Sheet to another Workbook in C#

I have an excel sheet which contains a Signature Line. I tried to copy this sheet to another workbook, but the values of the sheet can be copied, except the signature line. I think this copy method is based on cells.
How to get signature line to another workbook. Here is my code
Excel._Application xlApp;
Excel.Workbook xlTemplateWB;
Excel.Workbook xlTempWB;
object missing = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlApp.Visible = true;
//Open Bench Sheet Template
xlTemplateWB = xlApp.Workbooks.Open(#"C:\TempProjects\test.xlsx", 0, true, 5, "",
"", false, Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);
//Save As a temporary workbook
xlTemplateWB.SaveAs(#"C:\\TempProjects\mytmp.xlsx");
//Open temporary workbook
xlTempWB = xlApp.Workbooks.Open(#"C:\TempProjects\my.xlsx", 0, false, 5, true, "",
true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
xlTemplateWB.Worksheets.Copy(xlTempWB.Worksheets["Sheet1"]);
xlTemplateWB.Close(true, missing, missing);
releaseObject(xlTemplateWB);
xlTempWB.Save();
//Close Workbooks
xlTempWB.Close(true, missing, missing);
xlApp.Quit();
//Release Objects
releaseObject(xlTempWB);
releaseObject(xlApp);

How to check cell contain filter or not in excel sheet through oledb reader?

How to check cell contain filter or not in excel sheet through oledb excel reader?
want method or code for the same..

I had some solution with Interop you can check this , it may resolve your problem...
public bool IsFilterExistInExcel(string excelpath)
{
bool IsFilterExist=false;
Microsoft.Office.Interop.Excel.Application excelApp = null;
Microsoft.Office.Interop.Excel.Workbooks workBooks = null;
Microsoft.Office.Interop.Excel.Workbook workBook = null;
Microsoft.Office.Interop.Excel.Worksheet workSheet;
excelApp = new Microsoft.Office.Interop.Excel.Application();
workBooks = excelApp.Workbooks;
workBook = workBooks.Open(excelpath, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
workSheet = workBook.Worksheets.get_Item(1);
IsFilterExist = workSheet.AutoFilterMode;
return IsFilterExist;
}

Add datafrom textfile to excel worksheet and save

Hello There,
I am trying to enter data from text to excel and save it under particular worksheet name. It works if there is only 1 worksheet but it doesn't work when I call same code again as it overwrites the excel file. I was wondering if I can copy data from text and add to worksheet. I have used clipboard method but it throws STA error. I repeat copy text file to worksheet again and again. Here is my code: help is appreciated.
a_Books.OpenText(reportloc + ".txt", Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, 1,
Microsoft.Office.Interop.Excel.XlTextParsingType.xlDelimited, Microsoft.Office.Interop.Excel.XlTextQualifier.xlTextQualifierDoubleQuote,
false, true, false, false, false, false, a_Opt, a_Opt, a_Opt, a_Opt, a_Opt);
a_Book = a_Excel.Workbooks.Add(a_Opt);
a_Book.Sheets.Add();
Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)a_Book.ActiveSheet;
worksheet.Activate();
worksheet.Name = reportname;
FormatRaw_Data(worksheet);
a_Book.SaveAs(reportloc + ".xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, a_Opt, a_Opt, a_Opt, a_Opt, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, a_Opt, a_Opt, a_Opt, a_Opt, a_Opt);

I am not sure how you insert the new data, but if you are writing to the same worksheet and writing to the same cells, then yes it would always override it.
Solution:
Add a new worksheet, or change the range where you write to, to avoid loss of data.
EDIT:
On your code when you add the worksheet you select the active worksheet thats why it always writes to the same worksheet you have to select the new worksheet like this:
a_Book.Sheets.Add();
Microsoft.Office.Interop.Excel.Worksheet worksheet = a_Book.Sheets[a_Book.Sheets.Count - 1];
worksheet .Name = "You can put a name";

Use Code Below:
Read the excel. Make sure it exists:
a_Book = a_Excel.Workbooks.Open(reportloc + ".xls", 0, false, 5, "", "", false, XlPlatform.xlWindows, "\t", true, false, 0, true, false, false);
Use TexttoColumns Property:
for (int i = 0; i < range.Rows.Count; i++)
{
range.Rows[i].Value = lines[i];
range.Rows[i].TextToColumns(
range.Rows[i],
Microsoft.Office.Interop.Excel.XlTextParsingType.xlDelimited,
Microsoft.Office.Interop.Excel.XlTextQualifier.xlTextQualifierNone,
false,
true
);
}

How to copy an Excel Worksheet from one Workbook to another

I have been searching online for an answer to this. There are dozens of "solutions", but nothing seems to work right. The application I'm building (using C#) pulls data from a mdb querydef and creates an Excel workbook with two worksheets. That part works perfectly. Now for the part that should be simple: I have a workbook with multiple worksheets (each worksheet will calculate the data differently) I need the code to open the "template" workbook, copy the correct worksheet, and place the copy in the newly created workbook with the other two worksheets. Here's a sample of the code that I feel "should" work:
_Application xlApp;
Workbook xlTemplateWB;
Workbook xlTempWB;
object missing = System.Reflection.Missing.Value;
xlApp = new ApplicationClass();
xlApp.Visible = true;
//Open Bench Sheet Template
xlTemplateWB = xlApp.Workbooks.Open(Elmnt.getDBPath() + TEMPLATENAME, 0, true, 5, "", "",
false, XlPlatform.xlWindows, "", true, false, 0, true, false, false);
//Open temporary workbook
xlTempWB = xlApp.Workbooks.Open(XLTempDir + XLTempName, 0, false, 5, true, "", true,
XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
//Copy "BOD" Worksheet
xlTempWB.Worksheets.Copy(xlTemplateWB.Worksheets["BOD"]);
xlTempWB.Save();
//Close Workbooks
xlTempWB.Close(true, missing, missing);
xlTemplateWB.Close(true, missing, missing);
xlApp.Quit();
//Release Objects
releaseObject(xlTempWB);
releaseObject(xlTemplateWB);
releaseObject(xlApp);

Based on my reading of the MSDN documentation, Worksheet.Copy() will only work within a Workbook. Your C# syntax looks correct.
There are a couple of ways to approach this:
Duplicate the entire template workbook (using WorkBook.SaveCopyAs()) and delete what you don't need.
Select the range you want to move and use the clipboard (Range.Select; Range.Copy; Range.Paste;) to copy it.
Hope this helps.

Thank you for your help. After trying a few more things, I found that the only thing I could get to work was copying the whole workbook and deleting the non-applicable worksheets. I feel that this is very cumbersome, so if anyone finds a better way to do it, I'm all ears. Here's the code that I ended up using:
_Application xlApp;
Workbook xlTemplateWB;
Workbook xlTempWB;
object missing = System.Reflection.Missing.Value;
xlApp = new ApplicationClass();
xlApp.Visible = true;
//Open Bench Sheet Template
xlTemplateWB = xlApp.Workbooks.Open(Elmnt.getDBPath() + TEMPLATENAME, 0, true, 5, "", "",
false, XlPlatform.xlWindows, "", true, false, 0, true, false, false);
//Save As a temporary workbook
xlTemplateWB.SaveAs(XLTempDir + XLTempName);
xlTemplateWB.Close(true, missing, missing);
releaseObject(xlTemplateWB);
//Open temporary workbook
xlTempWB = xlApp.Workbooks.Open(XLTempDir + XLTempName, 0, false, 5, true, "", true,
XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
//Remove non-applicable worksheets
for (int i = xlTempWB.Sheets.Count; i > 0; i--)
{
if (((Worksheet)xlTempWB.Sheets[i]).Name != bchSheet)
{
xlApp.DisplayAlerts = false;
((Worksheet)xlTempWB.Sheets[i]).Delete();
xlApp.DisplayAlerts = true;
}
}
xlTempWB.Save();
//Close Workbooks
xlTempWB.Close(true, missing, missing);
xlApp.Quit();
//Release Objects
releaseObject(xlTempWB);
releaseObject(xlApp);
