StreamReader throws an exception if I attempt to open a .csv file which
is also opened by Excel.
I checked this list and found what I though was the solution, first
open the file stream in read only,
But unfortunately that doesn't work either
Stream s = File.OpenRead(f ilename);
using (StreamReader sr = new StreamReader(s) )
{
}
File.OpenRead still throws the "can not access file" exception,
however I can open the file in Notepad at the same time as it is opened
in Excel.
Is this another bug in .NET, and is there any workaround ?
Thanks

I havent looked anything up, but it sounds like excel opens a csv with
an exclusive file lock.
Try opening the file by passing in the filename into StreamReader
instead of opening a stream first from the file:
StreamReader sr = new StreamReader("f ile.csv");
Does that still throw an exception?
Hope this helps!

That was the first thing I did, but unfortunately that doesn't work
either, and that is the reason why I tried the other way.
The weird thing is that I can open the same csv file with notepad while
open in Excel with no problem.

I found the question interesting, and couldn't figure it out myself,
which was a little crazy, but found the answer online, and it works,
but I couldn't explain to you why. http://tinyurl.com/pw2xs
StreamReader reader = new StreamReader(ne w FileStream(@"fi le.csv",
FileMode.Open, FileAccess.Read , FileShare.ReadW rite));

yep - that works, thank you very much.
I think what does the trick is to set the share to ReadWrite instead of
Read.

I need to edit the text in many files so I'm writing a small routine to do
this.
First I have a method that loops through all the files in a directory and
passes the full file path to another method (ReadFile).
I'm going to use this to edit the file paths in all of my WMP play lists.
When I run this the string variable is not being changed using the replace
method. Here's what I have:
