Close an app in C#

[Richie]

Hi all,

I want to close excel application from C#, this is the piece of code I am
trying

"System.Runtime .InteropService s.Marshal.Relea seComObject(exc elApp);"

GC.Collect();

It ain't working ! Any ideas please !!

Thanks.

Assuming that your variable excelApp is just a reference to an Excel
Application, all you have to do is call excelApp.Quit() ;

Re: Close an app in C#

Hi Richie,

This is fine, but on viewing "Task List" the application tab shows
"Excel.exe" running. And if I run the program again the message
"Administra tor is using the file, file will open in readonly mode" shows.

Any ideas ?

Re: Close an app in C#

It sounds like you may be holding a reference to some of the Excel COM
objects. Did you try calling ReleaseComObjec t until it returns 0 on all your
references before calling Quit()?
