使用方式：
string spname = ChineseToPinyinHelper.ConvertToSP("姓名"); //获取名字首拼 string qpname = ChineseToPinyinHelper.ConvertToQP("姓名"); //获取名字全拼
结果：spname是XM，qpname是XingMing。
如果要转换字母大小写可用：ToUpper()转大写，ToLower()转小写。
例如有个字符串string testStr=“AbcDefg”;
（1）转换为大写：string UpTestStr=testStr.ToUpper();
转换后UpTestStr结果为:ABCDEFG
（2）转换为小写：string LowTestStr=testStr.ToLower();
转换后LowTestStr结果为：abcdefg
