推荐答案

如果您正在寻找替换所有转义字符codeS，不仅是$ C $下 @ ，你可以使用这个片段的code进行转换：

If you are looking to replace all escaped character codes, not only the code for @, you can use this snippet of code to do the conversion:

public static string UnescapeCodes(string src) {
    var rx = new Regex("\\\\([0-9A-Fa-f]+)");
    var res = new StringBuilder();
    var pos = 0;
    foreach (Match m in rx.Matches(src)) {
        res.Append(src.Substring(pos, m.Index - pos));
        pos = m.Index + m.Length;
        res.Append((char)Convert.ToInt32(m.Groups[1].ToString(), 16));
    }
    res.Append(src.Substring(pos));
    return res.ToString();
}

在code依赖于一个普通的前pression找到十六进制数字的所有序列，将它们转换为 INT ，以及铸造结果值到字符。

The code relies on a regular expression to find all sequences of hex digits, converting them to int, and casting the resultant value to a char.
