UNICODE十六進制的數組轉成中英文

實現char*轉換成中英文，每兩個char合成一個wchar_t：

[cpp]view plaincopy

//?UNICODE十六進制數組轉成中英文??

//?hex?array?to?wchar_t*??

//?wchs?==?NULL,?wchsLen?as?output(the?size?of?wchs?will?be?used)??

//?error:?return?-1??

int?YCodec::HexArray2WChars(char*?hexarry,?int?hexarrylen,?wchar_t*?wchs,?int*?wchslen)??

{??

????if(hexarry?==?NULL?||?hexarrylen<=0)?return?-1;??

????if(wchs?==?NULL){??

????????*wchslen?=?hexarrylen/2?+?(hexarrylen%2==0???0?:?1);??

????????return?1;??

????}??

????memset(wchs,?0,?*wchslen?*?sizeof(wchar_t));??

????char?tmp[3];??

????char*?phex?=?hexarry;??

????wchar_t*?pwchs?=?wchs;??

????for(int?i=0;?i<hexarrylen;?i++){??

????????memset(tmp,?0,?3);??

????????tmp[0]?=?*phex++;??

????????if(++i?>=?hexarrylen)????break;??

????????tmp[1]?=?*phex++;??

????????//?two?char?to?a?hex??

????????unsigned?short?hex?=?0x0;??

????????hex?=?(tmp[0]?&?0xff)?<<?8;??

????????hex?|=?tmp[1]?&?0xff;??

????????//?hex?to?wchar_t??

????????*pwchs++?=?(wchar_t)hex;??

????}??

??

????return?1;??

}??

調用實例：

[cpp]view plaincopy

<span?style="white-space:pre">??</span>//wchar_t*?unicode?=?NULL;??

????char?ascii[]?=?{0x62,?0x4b,?0x67,?0x3a,???

????????????????????0x53,?0xf7,?0x4e,?0x3a,??

????????????????????0x00,?0x31,?0x00,?0x38,??

????????????????????0x00,?0x38,?0x00,?0x38,??

????????????????????0x00,?0x37,?0x00,?0x36,??

????????????????????0x00,?0x35,?0x00,?0x35,??

????????????????????0x00,?0x32,?0x00,?0x31,??

????????????????????0x00,?0x30,?0x76,?0x84??

????};??

????int?wchslen?=?0;??

????YCodec?yCodec;??

????//?hex?array?to?wchar_t*??

????if(yCodec.HexArray2WChars(ascii,?32,?NULL,?&wchslen)?!=?-1){??

????????wchar_t*?wchs?=?new?wchar_t[wchslen+1];??

????????memset(wchs,?0,?sizeof(wchar_t)*(wchslen+1)?);??

????????int?n?=?yCodec.HexArray2WChars(ascii,?32,?wchs,?&wchslen);??

????????if(n?!=?-1){??

????????????//?wchar_t?to?CString??

????????????CString?tmp;??

????????????wchar_t?*?pwch?=?wchs;??

????????????for(int?i=0;?i<wchslen;?i++)?tmp.AppendChar(*pwch++);??

????????????m_Disp.SetWindowTextW(tmp);??

????????}??

??

????????delete?[]wchs;??

????}??

在MFC程序中測試通過。

已實現把0x62, 0x4b, 0x67, 0x3a, 0x53, 0xf7, 0x4e, 0x3a, 0x00, 0x31, 0x00, 0x38, 0x00, 0x38, 0x00, 0x38, 0x00, 0x37, 0x00, 0x36, 0x00, 0x35, 0x00, 0x35, 0x00, 0x32, 0x00, 0x31, 0x00, 0x30, 0x76, 0x84這一串unicode的十六進制字符數組轉成中英文。

結果為：

手機號為18887655210的

基本測試通過，暫未發現神馬問題。
