下面小编就为大家带来一篇.Net(c#)汉字和Unicode编码互相转换实例。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧

{"Tilte": "\u535a\u5ba2\u56ed", "Href": "http://www.jb51.net"}

经常遇到这样内容的json字符串,原来是把其中的汉字做了Unicode编码转换。

Unicode编码:

将汉字进行UNICODE编码,如:“王”编码后就成了“\王”,UNICODE字符以\u开始,后面有4个数字或者字母,所有字符都是16进制的数字,每两位表示的256以内的一个数字。而一个汉字是由两个字符组成,于是就很容易理解了,“738b”是两个字符,分别是“73”“8b”。但是在将 UNICODE字符编码的内容转换为汉字的时候,字符是从后面向前处理的,所以,需要把字符按照顺序“8b”“73”进行组合得到汉字。

 Unicode/汉字互转实现:

/// <summary>
/// <summary>
/// 字符串转Unicode
/// </summary>
/// <param name="source">源字符串</param>
/// <returns>Unicode编码后的字符串</returns>
public static string String2Unicode(string source)
{
 byte[] bytes = Encoding.Unicode.GetBytes(source);
 StringBuilder stringBuilder = new StringBuilder();
 for (int i = 0; i < bytes.Length; i += 2)
 {
  stringBuilder.AppendFormat("\\u{0}{1}", bytes[i + 1].ToString("x").PadLeft(2, &#39;0&#39;), bytes[i].ToString("x").PadLeft(2, &#39;0&#39;));
 }
 return stringBuilder.ToString();
}

/// <summary>
/// Unicode转字符串
/// </summary>
/// <param name="source">经过Unicode编码的字符串</param>
/// <returns>正常字符串</returns>
public static string Unicode2String(string source)
{
 return new Regex(@"\\u([0-9A-F]{4})", RegexOptions.IgnoreCase | RegexOptions.Compiled).Replace(
     source, x => string.Empty + Convert.ToChar(Convert.ToUInt16(x.Result("$1"), 16)));
}
