如何编写自定义Regex以匹配字符串

本文关键字：字符串 Regex 何编写 自定义 | 更新日期: 2023-09-27 18:16:49

我正在开发一个动态短信模板，下面是我的代码

我的原始短信模板像这个

string str="Dear 123123, pls verify your profile on www.abcd.com with below login details: User ID : 123123 Password: 123123 Team- abcd";

这里123123可以被任何东西取代，比如下面的ex-

Dear Ankit, pls verify your profile on www.abcd.com with below login details: User ID : Ankit@123 Password: Ankit@123 Team- abcd

现在，我如何确保字符串匹配除123123之外的所有内容，123123可以是任何动态值，如Ankit,Ankit@123

string ss="Dear Ankit, pls verify your profile on www.abcd.com with below login details: User ID : 123 Password: 123 Team- abcd";
 Regex Re = new Regex("What Regex Here");
if(Re.IsMatch(ss))
        {
            lblmsg.Text = "Matched!!!";
        }
        else
        {
            lblmsg.Text = "Not Matched!!!";
        }

如何编写自定义Regex以匹配字符串

@"^Dear ('S+?), pls verify your profile on www'.abcd'.com with below login details: User ID : ('S+) Password: ('S+) Team- abcd$"
// A ^ to match the start, $ to match the end, '. to make the dots literal
// ('S+) to match "one or more not-whitespace characters" in each of the 123123 places.
// @"" to avoid usual C# string escape rules
// Not sure what happens to your template if the name or password has spaces in.

例如

using System;
using System.Text.RegularExpressions;
class MainClass {
  public static void Main (string[] args) {
    string ss="Dear Ankit, pls verify your profile on www.abcd.com with below login details: User ID : 123 Password: 123 Team- abcd";
        Regex Re = new Regex(@"^Dear ('S+), pls verify your profile on www'.abcd'.com with below login details: User ID : ('S+) Password: ('S+) Team- abcd$");
        if(Re.IsMatch(ss))
        {
           Console.WriteLine ("Matched!!!");
        }
        else
        {
            Console.WriteLine ("Not Matched!!!");
        }
  }
}
