Delete a file

[Neven Klofuar]

hi,

I have a problem when trying to delete a file.

I have to extract some information from a file, and then I have to delete
it. When I try to delete it after I read it, I get a "Access denied" error.

help pls, Neven

********************************
StreamReader sr = new StreamReader(sFolderArhiva + sShortFileName);
while ((sLine = sr.ReadLine()) != null) {
try {
if (sLine.Substring(0, "ApplicationItem=".Length) ==
"ApplicationItem=") {
docType =
DohvatiTipDokumenta_TipDokumenta(sLine.Substring("ApplicationItem=".Length));
}
} catch (){}

try {
if (sLine.Substring(0, "ApplicationTag=".Length) ==
"ApplicationTag=") {
ID = sLine.Substring("ApplicationTag=".Length);
}
} catch {}
}

sr.Close();
sr.Dispose();

Hi Neven Klofuar,

Are you sure you aren't holding the file in some other part of your code,
or another program like a text editor. Can you delete the file manually?

A tip when using disposable/closable objects use a using statement

Instead of

StreamReader sr = new StreamReader(sFolderArhiva + sShortFileName);
// additional code here
sr.Close();
sr.Dispose();

Use

using(StreamReader sr = new StreamReader(sFolderArhiva + sShortFileName))
{
// additional code here
}

Makes the scope of the streamreader easier to see.

Neven,

Check if ASPNET account (unless you use impersonation) has write access?

Thanks for the answers, I noticed that file I'm trying to delete has a
read-only property, so I have to find a way to remove that property.

Removing the ReadOnly attribute can be done like this

FileInfo fi = new FileInfo(sFolderArhiva + sShortFileName);

if((fi.Attributes & FileAttributes.ReadOnly) > 0)
fi.Attributes -= FileAttributes.ReadOnly;

fi.Delete();

Thank you all for the help !!!
