C#: silent access to opened file

Question

Possible Duplicate:
Read file which is in use?

I have a such situation/question:

One txt file opened at present time by some program. This program writes some log stuff into file.
My C# program should open that file in read-only mode but access should be silent and should not block access to file.

What C# function(s) could help me?

Thanks in advance.

You just have to pass the appropriate parameters to the File.Open() method:

using (var stream = File.Open("path", 
   FileMode.Open, 
   FileAccess.Read, 
   FileShare.ReadWrite))
{
    // You can read, they (logger) can write
}

The FileShare flag allows to open an opened file.
