精确的正则表达式模式匹配一​​个字符串与单引号 [英] Exact Regex Pattern Match of a string with single quotes

问题描述

大家好，



我有一个包含单引号的字符串，例如他和'她'是我的爸爸朋友。我想用Latha取代'她'。那么请你告诉我这是否可行。以下示例适用于没有单引号的完全匹配。但单引号却失败了。请帮忙。

  string  pattern =  @  \ bLatha \ b; 
  string  input =  他和她是我父亲的朋友们; 
  string  result = Regex.Replace（input，pattern， 她，RegexOptions.None）; 

结果是：他和Latha是我爸爸的朋友



< pre lang =c＃> string pattern = @ \bLatha\b;
string input = 他和'她是我爸爸的朋友;
string result = Regex.Replace（input，pattern， '她'，RegexOptions.None）;

结果是：他和'她'是我的爸爸朋友



期望的结果是：他和Latha是我爸爸的朋友





请告诉我你的建议。



谢谢&此致，

Mathi。

解决方案

试试这个：

  const   string  pattern =   Latha; 
  const   string  input =  他和'她'是我爸爸的朋友; 
  var  regExpr =  new 正则表达式（  \'。* \'，RegexOptions.IgnoreCase）; 
  var  result = regExpr.Replace（input，pattern）; 

这应该工作，单引号与否：

 使用系统; 
 使用 System.Text.RegularExpressions; 
 
  public   class 计划
 {
  public   static   void  Main（）
 {
  string  pattern =  @  \ '？she\'？; 
  string  input =  他和'她是我爸爸的朋友; 
  string  result = Regex.Replace（input，pattern，  Latha，RegexOptions.None）; 
 Console.WriteLine（result）; 
} 
} 

试试这个：

  string  pattern =  '她'; 
  string  input =  他和'她是我爸爸的朋友; 
  string  result = Regex.Replace（input，pattern，  Latha，RegexOptions.None）; 

我相信你混淆了模式和替换。

Hi All,

I have a string which contains single quotes say for example "He and 'she' are my Dad friends". I want to replace 'she' with Latha. So Could you please let me know whether this is possible. The below example works for exact match without single quotes. But with single quote this fails. Please help.

string pattern = @"\bLatha\b"; 
string input = "He and she are my Dad friends"; 
string result = Regex.Replace(input, pattern, "she", RegexOptions.None); 

result is : He and Latha are my Dad friends

string pattern = @"\bLatha\b"; 
string input = "He and 'she' are my Dad friends"; 
string result = Regex.Replace(input, pattern, "'she'", RegexOptions.None); 

result is : He and 'she' are my Dad friends

Expected result is : He and Latha are my Dad friends


Kindly let me know your suggestions.

Thanks & Regards,
Mathi.

解决方案

Try this:

const string pattern = "Latha";
const string input = "He and 'she' are my Dad friends";
var regExpr = new Regex("\'.*\'", RegexOptions.IgnoreCase);
var result = regExpr.Replace(input, pattern);

This should work, single quote or not:

using System;
using System.Text.RegularExpressions;

public class Program
{
    public static void Main()
    {
        string pattern = @"\'?she\'?";
        string input = "He and 'she' are my Dad friends";
        string result = Regex.Replace(input, pattern, "Latha", RegexOptions.None);
        Console.WriteLine(result);
    }
}

Try this:

string pattern = "'she'";
string input = "He and 'she' are my Dad friends";
string result = Regex.Replace(input, pattern, "Latha", RegexOptions.None);

I believe you mixed up the pattern and replacement.
