Hello,

I have the following reader function :

public static string[] fileReadAllLines(string strFileName)
{
ArrayList content = new ArrayList();

using (StreamReader sr = File.OpenText(strFileName))
{
string input;
while ((input = sr.ReadLine()) != null)
{
content.Add(input);
}
sr.Close();
}

return toStringArray(content);
}

which also can be replaced with :

public static string[] fileReadAllLines(string strFileName)
{
return File.ReadAllLines(strFileName);
}

Both those methods remove all special characters (é,è,ø,æ,...) from the
stream, what to do to get them ?

Thanks

Hi,

The StreamReader uses UTF-8 encoding if not told otherwise. In addition, File.OpenText is meant for UTF-8 encoded files.
Try changing your code to something like

using(FileStream fs = File.Open(strFileName, ...))
{
    using(StreamReader sr = new StreamReader(fs, Encoding.Default))
    {
        ...
    }
}

You don't have to close the StreamReader since the using statement will do it for you.

Happy coding!

This worked :-)
Thanks for your help Morten.

public static string[] fileReadAllLines(string strFileName)
{

ArrayList content = new ArrayList();
using (FileStream fs = File.Open(strFileName,
FileMode.Open, FileAccess.Read))
{
using (StreamReader sr = new StreamReader(fs,
Encoding.Default))
{
string input;
while ((input = sr.ReadLine()) != null)
{
content.Add(input);
}
}
}
return toStringArray(content);
}

Just out of interest, are you using .NET 1.1 or 2.0? 2.0 has
File.ReadAllLines(string, Encoding) which does the same thing, I
believe.

The code is a utility class for both .NET 2.0 and .NET CF which does not
support File.ReadAllLines() unfortunately...
