Convert ASCII in a byte array to string

Question

I seem to be having problems with my string conversions in C#. My application has received a byte array consisting of an ASCII string (one byte per character). Unfortunately

Answer 1

 byte[] exampleByteArray = new byte[] { 0x00, 0x52, 0x50, 0x4D, 0x20, 0x3D, 0x20, 0x32, 0x35, 0x35, 0x2C, 0x36, 0x30, 0x0A, 0x00 };
 string myString = System.Text.ASCIIEncoding.Default.GetString(exampleByteArray);

Result: myString = "\0RPM = 255,60\n\0"

Answer 2

var buffer = new byte[] { 0x00, 0x52, 0x50, 0x4D, 0x20, 0x3D, 0x20, 0x32, 0x35, 0x35, 0x2C, 0x36, 0x30, 0x0A, 0x00 }
    .Skip(1)
    .TakeWhile(b => b != 0x00).ToArray();

Console.WriteLine(System.Text.Encoding.ASCII.GetString(buffer));

Answer 3

byte[] exampleByteArray = new byte[] { 0x00, 0x52, 0x50, 0x4D, 0x20, 0x3D, 0x20, 0x32, 0x35, 0x35, 0x2C, 0x36, 0x30, 0x0A, 0x00 };
exampleByteArray = exampleByteArray.Where(x=>x!=0x00).ToArray(); // not sure this is OK with your requirements 
string myString =  System.Text.Encoding.ASCII.GetString(exampleByteArray).Trim();

Result :

RPM = 255,60

you can add this to listBox

listBox.Items.Add(myString);

Update :

As per new comment byte array can contain garbage after the trailing 0x00 (remnants of previous strings).

You need to skip first 0x00 and then consider bytes until you get 0x00, so you can use power of Linq to do this task. e.g ASCII.GetString(exampleByteArray.Skip(1).TakeWhile(x => x != 0x00).ToArray())
