Byte array to string

[Markus Freitag]

Hello,
I receive a byte array and have to convert it into a string.
I only need one character in my string.
How can I reach my goal?

resToClient = (char)2 + "PING" + (char)4 + "WORK" + (char)4 + "ACK" + (char)3;

//Current Output:
Encoding.UTF8.GetString(buffer, 0, sizeReceive) "\u0002PING\u0004WORK\u0003"
Encoding.ASCII.GetString(new byte[]{ 2 }); "\u0002" string


//Should be:
For ASCII 2 (STX) 3 (ETX) 4 (EOT) I need only one character inside my string not more.

Thanks in advance for your help.

Greetings Markus.


My attempts were.
var buffer = new byte[10000];

sizeReceive = tcpClient.Client.Receive(buffer, 0, buffer.Length, SocketFlags.None);

receiveBuffer += Encoding.UTF8.GetString(buffer, 0, sizeReceive).Replace('\u0002', '2').Replace('\u0003', '3').Replace('\u0004', '4');


byte[] chars = new byte[sizeReceive];
System.Buffer.BlockCopy(buffer, 0, chars, 0, sizeReceive);
//receiveBuffer += new string(chars);

foreach (var item in chars)
{
if (item < 30)
{
int t = (char)item;
receiveBuffer += (char)t;
}
else
receiveBuffer += Convert.ToChar(item);
}
