C#之使用StringHelper来处理汉字转拼音

StringHelper字符串处理帮助

现 5b4 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:
