The post found here provides code to save the workbook in a temporary file and overwrites the original file with that temporary copy.

Relevant snippet:

//[...]
string tmpName = Path.GetTempFileName();
File.Delete(tmpName);        
wb.SaveAs(tmpName, missing, missing, missing, missing, missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, missing, missing, missing, missing, missing);
wb.Close(false, missing, missing);
excel.Quit();
File.Delete(Fname);
File.Move(tmpName, Fname);
