.Net常用技巧_汉字转拼音类（除汉字外，其余的原样输出）
注：如果是多音字，则默认取第一个拼音。

调用时示例：
注：调用时最好写在KeyUp事件中
private void txtMaterialName_KeyUp(object sender, KeyEventArgs e)
{
//传入待处理的字符串或文本框内容，生成助记码
this.txtNnemonicCode.Text = MyTool.PinYinConver.CreateNnemonicCode(this.txtMaterialName.Text);
//传入待处理的字符串或文本框内容，生成拼音编码
this.txtSpellCode.Text = MyTool.PinYinConver.CreateSpellCode(this.txtMaterialName.Text);
}
