我想用string sentence = "My current address is #6789, Baker Avenue (CB)".代替#6789, Baker Avenue (。

正则表达式为#574, Tomson Street (

如何在C＃中执行此操作？

Answer 1

using System;
using System.Text.RegularExpressions;

public class Program
{
    public static void Main()
    {
        string address = "My current address is #6789, Baker Avenue (CB)";
        Regex regex = new Regex("#.+\\(");
        address = regex.Replace(address, "#574, Tomson Street (");
        Console.WriteLine(address);
    }
}

您需要退出开口支架。同样在c＃\中必须转义字符，因此我们需要组合\\（我从您的提案中删除了^和$。这些字符将模式锚定到短语的开头和结尾。事实并非如此。

尝试一下：

string sentence = "My current address is #6789, Baker Avenue (CB)";

var result = Regex.Replace(sentence, @"#\d+,[^(]+", "#574, Tomson Street ");

模式为#\d+,[^(]+。

这是一个哈希#，后跟至少一个数字\d+，逗号和至少一个不加括号的字符：[^(]+

使用正则表达式C＃替换字符串中的单词
