Have tried a few including excelApp.ActiveWorkbook.Close(0,0,0); but it does not always close down the version thats open any ideas please
It seems to add 4 then take of 3 so that one stays and the open instances of excel seems to grow

// FIND ALL THE DATA OFF THE SPEAD SHEET FOR THE DISECTION INTO THE ARRAY
        private void GetCSVData(String filePath)
        {
          //  String filePath = @"C:\aeltest\@3rdmill.csv";
            // EXTRACT THE FILE NAME FOR THE SITE
            int startstr = filePath.IndexOf("@");
            string FileNme = filePath.Substring(startstr, filePath.Length - startstr);

            Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
            Microsoft.Office.Interop.Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(filePath, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
            Microsoft.Office.Interop.Excel.Sheets excelSheets = excelWorkbook.Worksheets;
            Microsoft.Office.Interop.Excel.Worksheet excelSheet = (Microsoft.Office.Interop.Excel.Worksheet)excelSheets.get_Item(1);

            for (int intI = 1; intI < 100; intI++)
            {
                Microsoft.Office.Interop.Excel.Range range1 = (Microsoft.Office.Interop.Excel.Range)excelSheet.Cells[intI, 1];
                Microsoft.Office.Interop.Excel.Range range2 = (Microsoft.Office.Interop.Excel.Range)excelSheet.Cells[intI, 2];
                Microsoft.Office.Interop.Excel.Range range3 = (Microsoft.Office.Interop.Excel.Range)excelSheet.Cells[intI, 3];
                Microsoft.Office.Interop.Excel.Range range4 = (Microsoft.Office.Interop.Excel.Range)excelSheet.Cells[intI, 4];
                Microsoft.Office.Interop.Excel.Range range5 = (Microsoft.Office.Interop.Excel.Range)excelSheet.Cells[intI, 5];

                try
                {
                    string cellValue1 = range1.Value2.ToString();
                    string cellValue2 = range2.Value2.ToString();
                    string cellValue3 = range3.Value2.ToString();
                    string cellValue4 = range4.Value2.ToString();
                    string cellValue5 = range5.Value2.ToString();

                    String abc = cellValue1;
                    CSVData[intI, 1] = cellValue1;
           //         PullApartTheCSVString( cellValue1, cellValue2, cellValue3, cellValue4, cellValue5, intI);
                    savetoDB( FileNme, cellValue1, cellValue2, cellValue3, cellValue4, cellValue5, intI);

                    //        savetoDB( String FileName, int intI);

                }
                catch
                {
                  //  intI = 101;
                }
            }

Try writing this in the finally block
finally
{
excelApp.ActiveWorkbook.Close(0,0,0);
}

Open in new window



Or by using a using keyword for this

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();

you have indeed to close and even dispose all objects (using using suggested above is the best method for that.

Dim worksheet As New Microsoft.Office.Interop.Excel.Worksheet
worksheet = CType(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
CType(worksheet, Microsoft.Office.Interop.Excel._Worksheet).Activate()
    '        ' If wanting excel to shutdown...
CType(excel, Microsoft.Office.Interop.Excel._Application).Quit()

If you want to quit the Excel application wouldn't it be this:
excelApp.Quit();

Open in new window


This looks more like it's for closing a workbook.
excelApp.ActiveWorkbook.Close(0,0,0);

Open in new window
