    很多时候我们需要把汉字转换成拼音，比如姓名、城市名等。网上搜索了一把，把汉字转成拼音的代码很多，但大多都只是把汉字转成了拼音的首字母，比如把“深圳”转成了“sz”。那么如何把汉字转成全拼（“深圳”转成了“ShenZhen”。）呢？有的说汉字那么多根本做不到，有的说是要用字库。其实仔细分析一下，虽然汉字很多，但汉字的读音（忽略声调，因为我们不需要）却很有限。利用这个特点，我们把汉字转成拼音就不是一件很困难的事了！

代码：

    private void button1_Click(object sender, EventArgs e)
    {
        this.textBox2.Text = Hz2Py.Convert(this.textBox1.Text);
    }
