Chars received
-
Hi I am trying to figure out why my method keeps only showing me the first character from a sent string. I would like it to show all the characters that were sent.
public void OnDataReceived(IAsyncResult asyn)
{
try
{
SocketPacket socketData = (SocketPacket)asyn.AsyncState;int iRx = 0; iRx = socketData.currentSoc.EndReceive(asyn); char\[\] chars = new char\[iRx\]; System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder(); int charLen = d.GetChars(socketData.dataBuffer, 0, iRx, chars, 0); System.String szData = new System.String(chars); MessageBox.Show(szData);<<<<<<<<<<< -

Instead of
System.String szData = new System.String(chars)
you could try
StringBuilder str = new StringBuilder();
for (int x = 0; x < charLen; x++)
{
str.Append(chars[x]);
}I haven't had a problem with that.

Hate to break it you, but this had no effect.

What do you see when you watch the variables? [Edit]I see you don't like debugging - too much like hard work is it?[/Edit]

Here are the main possibilities: 1. you may be invoking a receive with a small buffer; if you were to ask for one byte, then you would only get one byte. 2. you might have an encoding mismatch between sender and receiver. e.g. if the sender uses Unicode, regular characters would look like real (ANSI) bytes and NULLs intertwined; an 8-bit encoder would react badly on the NULLs. 3. what EndReceive returns is the number of bytes, not characters, hence
char[] chars = new char[iRx];is wrong. IMO you should use [EDIT]Encoding.GetString()right away to convert bytes into a string.[/EDIT] :)Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] Nil Volentibus Arduum
