获得汉字字符串的首个拼音字母的缩写_[Asp.Net教程]

获得汉字字符串的首个拼音字母的缩写_[Asp.Net教程]

标题可能不太清楚,实现的功能如下:我爱中国-WAZG
1。汉字字符与英文字母之间区别
标准的asc表不包含汉字字符,因为一个asc字符只有1byte,就是8bit,8bit所能代表的数字范围,如果是有符号的好,因该为-128-127,无符号的话,应该为0-255。而我们知道,一个汉字字符,应该占有2个byte,表示范围应该为-32768-32767,所以汉字的asc,举例一段bit: 11002111,11111101它所代表的字符,应该超过了asc所能表述的范围,这时候就会产生溢出。所以占有两个byte的汉字字符的asc码应该为负的。
