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);     }
