==============

Here is one example of how you can import files with .NET's StreamReader:

static void ImportWithStreamReader(Args _args)
{
    Filename                filename = @'C:\Temp\importme.txt';           
    System.IO.StreamReader  reader;
    System.String           line;
    InteropPermission       interopPermission;
   
    interopPermission = new InteropPermission(InteropKind::ClrInterop);
    interopPermission.assert();

    reader = new System.IO.StreamReader(filename, 

                                       System.Text.Encoding::get_UTF8());

    line = reader.ReadLine();

    while (!System.String::IsNullOrEmpty(line))
    {
        // Do something with line

        line = reader.ReadLine();
    }

    reader.Close();
    reader.Dispose();
}

If you can work with the file as on big chunk of text you can get away with just reading once, using the ReadToEnd method.
