Question

My software needs to generate files on the filesystem that can be read by any other instance of my program, regardless of the user account it’s running under. The problem I’m having is that if a file is created under an admin account then I run into an UnauthorizedAccessException when trying to read the contents of the file under a different account. Here’s the code I’m using to create the file

using (var fileStream = File.Create(path))
using (var streamWriter = new StreamWriter(fileStream))
{
    streamWriter.Write(/*some data*/);
}

and to read from the file

using (var fileStream = new FileStream(fileName, FileMode.Open))
using (var streamReader = new StreamReader(fileStream))
{
    var idLine = streamReader.ReadLine();
    if (idLine != null) fileContents = idLine;
}

Thanks

If you want to change the access to your file, you have to use the AccessControl : http://msdn.microsoft.com/en-us/library/9c13ttb3.aspx
