中文字符转换成拼音全码

1. 这个小程序可将中文字符转换成拼音码,如遇非中文字符,则返回字符本身,效果图如下:

（注: 此程序也可改写为返回字符拼音全码的首个字符,这个应用可以在程序中创建拼音快捷码）

2.  程序代码如下:

    /// <summary>
    /// 此方法集合汉字存储于数据库,1列为汉字,1列为拼音码,可应用于输入拼音码检索
    /// 拼音码的全码可以处理为截取首字符的快捷码
    /// </summary>
    public partial class Form1 : DevComponents.DotNetBar.Office2007Form
    {
        /// <summary>
        /// 拼音码 value
