推荐答案

将12，twelth或第12替换为：12：

This replaces "12," "twelth," or "twelfth," with: "twelve:"

// required
using System.Text.RegularExpressions;

//somewhere in a method

string s = @"additional twelfth consecutive month(s) (""Renewal Term"") by giving";

Regex r = new Regex(@"\b12\b|\btwelth\b|\btwelfth\b");

s = r.Replace(s, "twelve");
