删除regex不工作的\u字符[关闭]

我不知道你有什么问题。以下代码(带第一个regex)有效:

using System;
using System.Text.RegularExpressions;


public class Program
{
    public static void Main()
    {
        var text = @":art!art@irc.org private #timing :\u000314CODEERROR:\u0003 [\u000304X012\u0003] Server time is different than UTC";
        var res = Regex.Replace(text, @"\\u0{3}3\d{0,2}", string.Empty);
        System.Console.WriteLine(res);
    }
}

输出:

:art!art@irc.org private #timing :CODEERROR: [X012] Server time is different than UTC
