C＃：防止子进程锁定呼叫者文件夹

Question

I start app1.exe which is located in the folder myFolder.

This app1.exe calls another app2.exe via Process.Start in C#.

I close app1.exe.

app2.exe tries to delete myFolder but it says it is locked because app2.exe is using it even though app2.exe isn't doing anything with myFolder.

Note: If I start app2.exe alone (by clicking .exe), I am able to delete myFolder. It only prevents me if app2.exe was started from app1.exe.

---

Is there a way to allow a separate process to delete its caller folder? Both app1.exe and app2.exe are in C#.

Answer 1

Check the ProcessStartInfo ( Process.StartInfo property) involved when you start app2 . It may well be that app2 is starting with WorkingDirectory set to the folder in which app1 is located. If that's the case you could either trying setting WorkingDirectory to somewhere else before you start app2 or you can have app2 change the directory after it has been started.
