推荐答案

Regex.Matches方法可用于提取字符的十进制值，然后Select 的Select 方法可用于转换每个字符十进制值转换为字符，然后可以从chars 数组构造string ，如下所示:

The Regex.Matches method can be used to extract the decimal values of the characters and then Select method of IEnumerable can be used to convert each decimal value into character and then a string can be constructed from the array of chars as shown below:

string str =  "& #1047;& #1076;& #1088;& #1072;& #1074;& #1077;& #1081;, & #1089;& #1074;& #1103;& #1090;";

MatchCollection charNums = Regex.Matches(str,@"(?<=#\s*)\d+(?=\s*)", 
                                    RegexOptions.CultureInvariant);
string strFinal = new string(charNums.OfType<Match>().Select (
                            m => (char)Convert.ToInt32(m.Value)).ToArray());
Console.WriteLine (strFinal);

输出

Output

Здравейсвят

没有用漂亮的整齐的方法包装，但这也有效:

Not wrapped in a nice tidy method, but this also works:

string str = "& #1047;& #1076;& #1088;& #1072;& #1074;& #1077;& #1081;, & #1089;& #1074;& #1103;& #1090;";

 str = Regex.Replace(str, @"& #(\d+);", m => ((char)int.Parse(m.Groups[1].Value)).ToString());

输出:

Output:

Здравей, свят
