Answer 1

string[] arr=str.Split(new string[]{"^"},StringSplitOptions.StringSplitOptions.RemoveEmptyEntries);

Answer 2

Airs.Substring(Airs.LastIndexOf("^"), Airs.Length - Airs.LastIndexOf("^"));

Answer 3

    string s = "Airs_21=22APR08^CAN^PEK^HU7802^330^1845^2205^1^1^1^FAFF2550@CACC2210@YAYY1700@BA901530@HA851450@KA801360@LA751280@MA701190@JA000@V7000@W5000@";
            string[] ss = s.Split('^');
            string result = "";
            foreach (string s1 in ss)
            {
                if (s1.Contains("@"))
                {
                    result = s1;
                    break;
                }
            }
            Response.Write(result);
    //结果:FAFF2550@CACC2210@YAYY1700@BA901530@HA851450@KA801360@LA751280@MA701190@JA000@V7000@W5000@
