Hello,
I need to send data to COM port, but in cp1251 or cp866 encoding.
How can i convert string in UTF8 encoding, to byte[] in cp866?
Or how to set encoding to SerialPort?
In Windows application I use:
Encoding destinationEncoding = Encoding.GetEncoding(0x362);
Encoding unicode = Encoding.Unicode;
byte[] bytes = unicode.GetBytes("Test string"));
byte[] buffer = Encoding.Convert(unicode, dstEncoding, bytes);
SerialPort.Write(buffer, 0, buffer.Length);
NETMF only has native support for UTF8 so any encoding other than that you’d have to do manually…[italic]yikes[/italic] :o
This is a way, i found to convert encoding
Any optimisation ideas for faster converting?
//symbols array

}
//convert input string to bytes
public static byte[] GetBytes866(string strInput)
{
char[] inCharData = strInput.ToCharArray();
byte[] outBytes = new byte[inCharData.Length];

{

}
return outBytes;

This is very bad 
try this
return (byte)charIn;
Oh, yes ;D Thanks a lot!
