Any difference between File.ReadAllText() and using a StreamReader to read file contents?

Question

At first I used a StreamReader to read text from a file:

StreamReader reader = new StreamReader(dialog.OpenFile());
txtEditor.Text = reader.Read

Looking at the code within mscorlib, File.ReadAllText actually calls StreamReader.ReadToEnd internally!

private static string InternalReadAllText(string path, Encoding encoding, bool checkHost)
{
    string result;
    using (StreamReader streamReader = new StreamReader(path, encoding, true, StreamReader.DefaultBufferSize, checkHost))
    {
        result = streamReader.ReadToEnd();
    }
    return result;
}
