This resolved the issue for me. Your code becomes:
public Excel.Application excelApp = new Excel.Application(); public Excel.Workbooks workbooks; public Excel.Workbook excelBook; workbooks = excelApp.Workbooks; excelBook = workbooks.Add(@"C:/pape.xltx");
... Excel.Sheets sheets = excelBook.Worksheets; Excel.Worksheet excelSheet = (Worksheet)(sheets[1]); excelSheet.DisplayRightToLeft = true; Range rng; rng = excelSheet.get_Range("C2"); rng.Value2 = txtName.Text;
And then release all those objects, (Note: All the com object should be release, othewise the excel process won't be closed.)
System.Runtime.InteropServices.Marshal.ReleaseComObject(rng); System.Runtime.InteropServices.Marshal.ReleaseComObject(excelSheet); System.Runtime.InteropServices.Marshal.ReleaseComObject(sheets); excelBook .Save(); excelBook .Close(true); System.Runtime.InteropServices.Marshal.ReleaseComObject(xlBook); System.Runtime.InteropServices.Marshal.ReleaseComObject(workbooks); excelApp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
I wrap this in a try {} finally {}
to ensure everything gets released even if something goes wrong (what could possibly go wrong?) e.g.
public Excel.Application excelApp = null; public Excel.Workbooks workbooks = null; ... try { excelApp = new Excel.Application(); workbooks = excelApp.Workbooks; ... } finally { ... if (workbooks != null) System.Runtime.InteropServices.Marshal.ReleaseComObject(workbooks); excelApp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp); }
