UTF8 Question

[Nuno Magalhaes]

Why does (in the code below) the message should appear as "keep-alive -
keep-alive - test" but it only appears as "keep-alive - keep-alive".
That is why the last comparation (Equals) isn't getting true. Is it
from the "Convert.ToByte('\0')" that does the comparation false?
I'm shure that the strings are identical but it gives me false. Why?

Any help is appreciated, (Possible some UTF8 compatibility issues?)

Here's the code:
***************************************************************
byte[] connectionBytes=new byte[16];
for(int i1=index+12,i2=0;;i1++,i2++)
{
if(bytes[i1]=='\n')
{
connectionBytes[i2]=Convert.ToByte('\0');
break;
}
connectionBytes[i2]=bytes[i1];
}
string strTemp=Encoding.UTF8.GetString(connectionBytes).ToLower();
MessageBox.Show("keep-alive - "+strTemp+" - test");
if(Encoding.UTF8.GetString(connectionBytes).ToLower().Equals("keep-alive"))keepAlive=true;
else keepAlive=false;

keep-alive - test" but it only appears as "keep-alive - keep-alive".

Because the MessageBox will only show the string up to the first '\0'
character.

That is why the last comparation (Equals) isn't getting true. Is it
from the "Convert.ToByte('\0')" that does the comparation false?

Yes one string will have a null character at the end but the literal
"keep-alive" doesn't.

Thanks for the reply.
I solved the problem with a Substring(0,10) comparision.
