workBook.SaveAs(this.FileName ,Excel.XlFileFormat.xlWorkbookNormal,Missing.Value ,Missing.Value ,
Missing.Value ,Missing.Value ,Excel.XlSaveAsAccessMode.xlNoChange,Missing.Value ,Missing.Value ,Missing.Value ,
Missing.Value );
workBook.Saved = true;
workBook.Close(false,null,null); 
exApp.UserControl = false;
exApp.Quit ();
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(workSheet);
}
catch(Exception e1)
{
System.Diagnostics.Debug.WriteLine(e1.Message);
}
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(workBook);
}
catch(Exception e2)
{
System.Diagnostics.Debug.WriteLine(e2.Message);
}
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(exApp);
}
catch(Exception e3)
{
System.Diagnostics.Debug.WriteLine(e3.Message);
}
workSheet = null;
workBook = null;
exApp  = null;
System.GC.Collect();
