情景描述：由于任务需要，现有一用户表数据，用户名 字段 在新增用户时，输入中文和拼音两种，先要区分同时含有中文和拼音字母的用户名。由于数据很多，可以通过一段代码完成查询：
前提：在阅读本文之前可以先了解前一篇文章： C# 汉字转拼音 将中文转换成拼音 （注：该方法只支持常规字，多音字和生僻字不支持）
创建控制台程序：

在Program.cs加入以下代码
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks; namespace npoi
{
class Program
{
static void Main(string[] args)
{
string path = @"C:\Users\Jie\Desktop\data.txt";
System.Text.Encoding.GetEncoding("gb2312");
//ReadAllLines 必须设置默认编码，不然读取汉字会乱码
List<string> list = File.ReadAllLines(path, System.Text.Encoding.Default).ToList();
List<string> listhz = new List<string>();
List<string> listzm = new List<string>();
foreach (string s in list) {
if (Regex.IsMatch(s, @"^[\u4e00-\u9fa5]+$"))
{ listhz.Add(s);
}
else { listzm.Add(s);
}
} foreach (string hz in listhz) {
var hz2py = ChnToPh.convertCh(hz); foreach(string zm in listzm)
{
if (zm.ToLower() == hz2py.ToLower()) { Console.WriteLine(string.Format("{0}:{1}", hz, zm));
}
}
} Console.ReadLine();
}
}
}
新建 data.txt 如下
放置对应的目录。运行代码 如图：
