C# 汉字转拼音(全拼)

    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);
    }

2007年12月9日补充:一些生僻字转不了,比如:“睿”和“罡”字等。
