Hi
I want to convert from byte to string. How to do this. I used Serial port RS232 Communication Channel to get the value.

Please suggest me

C#

byte[] buff = new byte[8];
            buff[0] = 1;
            string readValue = "";
            int readcount = 1;
            int offset = 1;

            objport.Write(buff, offset, readcount);
            objport.Read(buff, offset, readcount);
            
            label7.Text = buff[1].ToString();         
            readValue = ByteArrayToString(buff); // here readvalue is 01c2000000000000

            if((readValue.Substring(0,1))=="A")
            {
            }

 public static string ByteArrayToString(byte[] ba)
        {
            StringBuilder hex = new StringBuilder(ba.Length * 2);
            foreach (byte b in ba)
                hex.AppendFormat("{0:x2}", b);
            return ( hex.ToString());
        }

Thanks in Advance

Hi palini

thanks for your support now My issue is fixed now. I written the code as below.

Regards
Sheethal

C#

double read1 = 0;
objport.DiscardInBuffer();
byte[] buff = new byte[8];
buff[0] = 1;
string readValue = "";
string[] readValue1 = new string[1];
int readcount = 1;
int offset = 1;
string sWord1 = "", sWord2 = "";
double dResult1 = 0;
double dMulFactor = 0;
double dResult = 0;
//  objport.ReadBufferSize = 0;
objport.Write(buff, offset, readcount);

do
{

}
while (objport.BytesToRead < 2);
byte[] buffer = new byte[objport.ReadBufferSize];
int bytesRead = objport.Read(buffer, 0, 2);
tString = BitConverter.ToString(buffer.ToArray(), 0, 2);
sWord2 = tString.Substring(0, 2);
sWord1 = tString.Substring(3, 2);
int value = Convert.ToInt32(sWord2, 16);

And the actual value is?
I mean, the ByteArrayToString function correctly returns the hexadecimal representation of every byte of the array.
