StringHelper字符串處理幫助
現在已經實現的功能有：
1.用給定的字符填充源字符串的左邊以達到指定的長度
2.用給定的字符填充源字符串的右邊以達到指定的長度
3.轉半角的函數(DBC case)
4.轉全角的函數(SBC case)
5.漢字轉拼音縮寫
6.取單個字符的拼音聲母
等等
演示一下:漢字轉拼音縮寫
我是那Windows窗體寫的
代碼:
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);
}
}
}
實現後的結果:
下面看一下StringHepler的代碼:
