Re: Excel exe is not getting closed ,even if we do GC.COllect relesing com object in asp.net

try with the following

// Garbage collecting
GC.Collect();
GC.WaitForPendingFinalizers();
// Clean up references to all COM objects
// As per above, you're just using a Workbook and Excel Application instance, so release them:
workbook.Close(false, Missing.Value, Missing.Value);
Marshal.FinalReleaseComObject(workbook);
Marshal.FinalReleaseComObject(xlApp);
