Hi John. Thanks for reply. My code :

Process proc = new Process();
proc.StartInfo.FileName = fileName;//c:\\test.cs
proc.Start();

bool closed = false;
do
{
try
{
// try to open a file stream
using (FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.None))
// if we get here, we didn't get an exception and the file is ready to be used
closed = true;
}
catch (Exception ex)
{
if (ex != null) {}
}
} while (!closed);

Everytime i get closed=true. So i can't detect when file closed. My scenario is correct ? Thanks.
