            {
                char currChar = buf[i];
                if (lastChar == '\r' &&
                    currChar == '\n')
                {
                    sb.Remove(sb.Length - 1, 1);
                    messageList.Add(new CommandData(sb.ToString()));
                    sb.Clear();

            }
            return messageList.ToArray();
        }有没有更好的方法

Answer 1

replace方法            string s = "aaaaadsdsd\rds\nd\r\ncc";
            s = s.Replace("\r\n","");

Answer 2

            var messageList = new List<CommandData>();
            TextReader reader = new StringReader(buffer.ToString());
            string lineData = string.Empty;
            while( (lineData = reader.ReadLine()) != null )
            {
                messageList.Add(new CommandData(lineData));
            }
            reader.Close();
            return messageList.ToArray();

Answer 3

对返回来的数据用Replace方法进行过滤

string Str = "Hello\0\0\0\0\0\0\0\0\0".Replace("\0", "");
