ToString Help[resolved]

[Magiaus]

byte b;
string s ="";

for(int i = 0; i < Stream.Length; i++)
{
    b = (byte)Stream.ReadByte();
    s += b.ToString("g");
}

I want ascci text to come out but all I get are numbers. Can anyone tell me about why and what to do. the Stream is from a text file that contains ascii text. I'm confused because I swear when I was using System.Console and reading it I used ToString("g").....
