winform学习日志（二十八）----------将汉字转化为拼音，正则表达式和得到汉字的Unicode编码
一：上图，不清楚的看代码注解，很详细了
二：具体代码
窗体代码
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Text.RegularExpressions; namespace ChineseToABC { public partial class Frm_Main : Form { public Frm_Main() { InitializeComponent(); } private void txt_Chinese_TextChanged(object sender, EventArgs e) { txt_PinYIn.Text = //调用拼音类的GetABC方法得到拼音字符串 new PinYin().GetABC(txt_Chinese.Text); } } }
拼音类代码
