下面小编就为大家带来一篇c#把unicode编码转换为gb编码的实例。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
实例如下：
public string unicodetogb(string text)
{
System.Text.RegularExpressions.MatchCollection mc = System.Text.RegularExpressions.Regex.Matches(text, "\\\\u([\\w]{4})");
if (mc != null && mc.Count > 0)
{
foreach (System.Text.RegularExpressions.Match m2 in mc)
{
string v = m2.Value;
string word = v.Substring(2);
byte[] codes = new byte[2];
int code = Convert.ToInt32(word.Substring(0, 2), 16);
int code2 = Convert.ToInt32(word.Substring(2), 16);
codes[0] = (byte)code2;
codes[1] = (byte)code;
text = text.Replace(v, Encoding.Unicode.GetString(codes));
}
}
else
{
}
return text;
}
