Reading file every 1 second

[Pujo Aji]

Hello,

I would like to read file during runtime(the other third party vendor
write the program and my program read it every second). I can't do it
until the third party vendor stop writing it. anyone can help?

Sincerely Yours,
Pujo

Hi,

FileStream constructor has a FileShare parameter.
I believe that setting it to "ReadWrite" allow you to
access read/write operation.
But there can be problem if "third party vendor" doesn't
allow to share that file.

Hi,

I think the third party vendor give the access, since I can open using
notepad and see the difference every 1 second.
I use this code before:
string sLN;
try {
using (TextReader tr = new StreamReader(FN )) {
sLN = tr.ReadLine();
while (sLN != null) {
//show in console
sLN = tr.ReadLine();
}
tr.Close();
}
}
catch {
//give some info;
}

How can I use the FileStream, FileShare parameter?

Sincerely Yours,

Hi,

Use a FileStream and decorate it with a StreamReader:

FileStream fs = new FileStream( file , FileMode.Open, FileAccess.Read )
StreamReader reader = new StreamReader( fs)

it may solve your problem.

cheers,

Hi,

I tried to implement your suggestion into my code:
string sLN;
try{
FileStream fs = new FileStream(File ,FileMode.Open, FileAccess.Read );
StreamReader reader = new StreamReader(fs );
sLN = reader.ReadLine ();
while (sLN != null) {
//write to console
sLN = reader.ReadLine ();
}
}
catch{
//Information
}

It doesn't work, the result is the same.Am I missing something?
