C#之使用StringHelper来处理汉字转拼音

StringHelper字符串处理帮助

现在已经实现的功能有：

1.用给定的字符填充源字符串的左边以达到指定的长度

2.用给定的字符填充源字符串的右边以达到指定的长度

3.转半角的函数(DBC case)

4.转全角的函数(SBC case)

5.汉字转拼音缩写

6.取单个字符的拼音声母

等等

演示一下:汉字转拼音缩写

我是那Windows窗体写的

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;namespace PyCodeDemo{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void label1_Click(object sender, EventArgs e)        {        }        private void button1_Click(object sender, EventArgs e)        {            this.label1.Text = StringHelper.PYConvert(this.textBox1.Text.Trim(), true);        }    }}

实现后的结果:

下面看一下StringHepler的代码:
