.net 汉字转拼音 - 输入汉字获取其拼音

首先，去微软官网下载Microsoft Visual Studio International Pack语言包，下载地址分别如下：
Microsoft Visual Studio International Pack 1.0 SR1、Microsoft Visual Studio International Feature Pack 2.0

下载后分别是“vsintlpack1.zip”、“Vsintlpack2.msi”、双击“Vsintlpack2.msi”安装、路径随意、但是要记得、因为一会要引用的、
安装“Vsintlpack2.msi”之后、解压“vsintlpack1.zip”、里面包含七个语言包、
　例如中文转拼音“CHSPinYinConv.msi”、简体繁体互转“CHTCHSConv.msi”等等。。

　在这里我们用到的是“CHSPinYinConv.msi”、双击安装成功后、打开Visual Studio、新建一个WinForm项目、窗体布局如上图所示、

首先：添加刚刚安装的语言包引用：

“D:\Program Files (x86)\Microsoft Visual Studio International Pack\Simplified Chinese Pin-Yin Conversion Library\ChnCharInfo.dll”
