Ok after some more testing I found that if I have 2 different files,
one
called test1.txt and the other called test2.txt and I wrap the code in
a
using statement I still have the same issue.

Now I am deleting the file successfully, but I have Googled this and
every solution doesn't work for me.
Here is the super short test code.
---
string filePath = Path.Combine(QRWatchedFolder, e.Name);
using (TextReader reader = File.OpenText(filePath))
{
textBox1.Text = textBox1.Text + reader.ReadToEnd();
reader.Close();
}

File.Delete(filePath);
---
The code is in a SystemFileWatcher_Created Event.

Thanks in advance!

Subject: [DotNetDevelopment] File Read Issues


I need some help with a file read issue.


I have a watched folder that reads the text file and writes it to a
standard
textbox. For testing purposes I have a file called text.txt on my
desktop that I copy
to the watched folder.

The first time I copy the file to the watched folder it reads it fine
and
deletes it from the watched folder.

Then if I take that file and copy it into the folder again I get the
following error.

The process cannot access the file . <path to the file in the watched
folder> . because it is being used by another process.

Here is my test code.
--------

string filePath = Path.Combine(QRWatchedFolder, e.Name);
FileStream file = File.Open(filePath, FileMode.Open, FileAccess.Read,
FileShare.ReadWrite);
StreamReader SR = new StreamReader(file);
textBox1.Text = textBox1.Text + SR.ReadToEnd() + Environment.NewLine;
SR.Close();
File.Delete(filePath);

--------
Now since the file is deleted , when it is copied again from the
desktop why
does it say the file is being used?

Am I not closing my StreamReader properly?

Any help would be greatly appreciated.
Greg
