最近在做項目時遇到這個問題,比如將漢字“沖”轉換後為 “51B2”,程序使用的是unicode字符集,下面是通過查資料後整理的解決方法:
//---------------------------------------------------------------------
//函數:W2C
//功能:將16位wchar_t轉換為 8位char[2]
//參數:w_cn為待轉換的16位字符,c_cn[]為轉換後的8位字符
//備注:wchar_t的高位字節應該存儲在char數組的低位字節
//作者:chuchong
//---------------------------------------------------------------------
void StyleConvert::W2C(wchar_t w_cn , char c_cn[])
{
//following code convert wchar to char
c_cn[0] = w_cn >> 8 ;
c_cn[1] = (char)w_cn ;
}
//-------------------------------------------------------------------
//函數:ConvertWCHARToHex
//功能:將16位字符串轉換為十六進制字符串
//參數:待轉換的字符串,字符串長度
//返回值:轉換後的字符串
//作者:chuchong
//-------------------------------------------------------------------
CString StyleConvert::ConvertWCHARToHex(CString Data, long nDataLength)
{
CString sResult("");
for (long nLoop=0; nLoop<nDataLength; nLoop++)
{
wchar_t ch = Data.GetAt(nLoop);
//將wchar_t轉換為char[2]
char c_cn[2]={'0'};
W2C(ch,c_cn);
static const char *hex = "0123456789ABCDEF";
for(int i=0;i<2;i++)
{
unsigned char chHexA = hex[((unsigned char)(c_cn[i]) >> 4) & 0x0f];
unsigned char chHexB = hex[(unsigned char)(c_cn[i]) & 0x0f];
sResult += (char)chHexA;
sResult += (char)chHexB;
}
}
return sResult;
}
