When i convert byte in string has a lot of unnecessary information c#

I need to convert this bytes in a string:

var smallDCWBytes = new byte[]
         {
              0xFE, 0x00, 0x00, 0xEF, 0xFF, 0xF8, 0x24, 0x16, 0x01, 0x04, 0x00, 0x00, 0x66, 0x37, 0x58, 0xCA,
              0xB8, 0x82, 0x00, 0x80, 0x53, 0x6D, 0x61, 0x6C, 0x6C, 0x20, 0x44, 0x43, 0x57, 0x20, 0x52, 0x65,
              0x63, 0x65, 0x69, 0x76, 0x65, 0x64
         };

var localDCWResponseText = System.Text.Encoding.ASCII.GetString(smallDCWBytes).Trim();

this is the answered that i received: "?\0\0???$\u0016\u0001\u0004\0\0f7X???\0?Small DCW Received"

I only need the "Small DCW Received", how is the better way to do this?

Actually it is doing what is requested, because it is converting every byte of your array. You can use:

var smallDCWBytes = new byte[]
     {
          0x53, 0x6D, 0x61, 0x6C, 0x6C, 0x20, 0x44, 0x43, 0x57, 0x20, 0x52, 0x65,
          0x63, 0x65, 0x69, 0x76, 0x65, 0x64
     };

var localDCWResponseText = System.Text.Encoding.ASCII.GetString(smallDCWBytes);

Or, if you are forced to use that array, you case do something like:

var smallDCWBytes = new byte[]
     {
          0xFE, 0x00, 0x00, 0xEF, 0xFF, 0xF8, 0x24, 0x16, 0x01, 0x04, 0x00, 0x00, 0x66, 0x37, 0x58, 0xCA,
          0xB8, 0x82, 0x00, 0x80, 0x53, 0x6D, 0x61, 0x6C, 0x6C, 0x20, 0x44, 0x43, 0x57, 0x20, 0x52, 0x65,
          0x63, 0x65, 0x69, 0x76, 0x65, 0x64
     };

var localDCWResponseText = System.Text.Encoding.ASCII.GetString(smallDCWBytes).Substring(21,18);
