Unicode and Chinese characters transcoding each other

\uxxxx This format is a Unicode notation that represents a character in which XXXX represents a 16-digit, range-0~65535. Unicode hexadecimal numbers can only contain numeric 0~9, uppercase letters A~F, or lowercase a~f. It is important to note that the size-to-end problem of Unicode, which is usually small-ended, such as \u5c0f, which represents the ' small ' word in Chinese, is converted to 10 binary is 9215, so the byte array should be 1592. Kanji to Unicode

private string Unicode2chinese (string strunicode)
{
    string[] splitstring = new string[1];
    Splitstring[0] = "\\u";
    string[] Unicodearray = Strunicode.split (splitstring, stringsplitoptions.removeemptyentries);
    StringBuilder sb = new StringBuilder ();

    foreach (string item in Unicodearray)
    {
        byte[] codes = new byte[2];
        int Code1, Code2;
        Code1 = Convert.ToInt32 (item. Substring (0, 2), (+);
        Code2 = Convert.ToInt32 (item. Substring (2), (+);
        Codes[0] = (byte) code2;//must be small end in front
        codes[1] = (byte) code1;
        Sb. Append (Encoding.Unicode.GetString (codes));
    }

    Return SB. ToString ();
}
