在C++中,将cstring(即char*或std::string)转换为wchar_t*通常涉及到字符编码的转换。cstring一般使用UTF-8或ASCII编码,而wchar_t*则使用宽字符编码,通常是UTF-16(在Windows上)或UTF-32(在某些Unix-like系统上)。以下是如何实现这一转换的步骤和代码示例: 1. 理解cstring和wchar_t*的数据类型和用途 cstring(cha...
string和CString均是字符串模板类,string为标准模板类(STL)定义的字符串类,已经纳入C++标准之中; CString(typedef CStringT > CString)为Visual C++中最常用的字符串类,继承自CSimpleStringT类,主要应用在MFC和ATL编程中,主要数据类型有char(应用于ANSI),wchar_t(unicode),TCHAR(ANSI与unicode均可); char*为C编程中...
1、将CString转换为const char* CString str = _T("231222"); std::string strDp = CStringA(str); //或: std::string strDp = CT2A(str, CP_ACP); 2、将const char*转换为wchar_t*类型 size_t len = strDp.length() + 1; size_t converted = 0; wchar_t * WStr = (wchar_t*)malloc...
1.CString转wchar_t CStringpath="asdf"; wchar_twstr[256]=path.AllocSysString(); 或者： wchar_twcstring[256]; MultiByteToWideChar(CP_ACP,0,path,-1,wcstring,256); 2.wchar_t转CString WideCharToMultiByte(CP_ACP,0,wcstring,256,path.GetBuffer(0),256,NULL,NULL); path.ReleaseBuffer(0...
unicode下CString 转为wchar_t：方法一：使用api：multibytetowidechar进行转换。char * pfilename = "d:\\校内项目\\qq.bmp"； //计算char *数组大小，以字节为单位，一个汉字占两个字节int charlen = strlen(pfilename)； //计算多字节字符的大小，按字符计算。int len = multibytetowidechar(cp_...
wchar_t转CString WideCharToMultiByte(CP_ACP,0,wcstring,256, path.GetBuffer(0),256,NULL,NULL); path.ReleaseBuffer(0); string 转 CString CString.format("%s", string.c_str()); char 转 CString CString.format("%s", char*); char 转 string ...
CString(typedef CStringT > CString)为Visual C++中最常用的字符串类,继承自CSimpleStringT类,主要应用在MFC和ATL编程中,主要数据类型有char(应用于ANSI),wchar_t(unicode),TCHAR(ANSI与unicode均可); char*为C编程中最常用的字符串指针,一般以'\0'为结束标志; ...
VC之CString,wchar_t,int,string,char*之间的转换 CString path = "asdf"; wchar_t wstr[256] = path.AllocSysString(); 或者: wchar_t wcstring[256]; MultiByteToWideChar(CP_ACP,0,path,-1,wcstring,256); 2. wchar_t转CString WideCharToMultiByte(CP_ACP,0,wcstring,256,path.GetBuffer(0),256,NULL...
wchar_t是UNICODE码,（1）多字节转成宽字节 wstring xx::converToWideChar( const string& str ){ int len = 0; len = str.length(); int unicodeLen = ::MultiByteToWideChar(CP_UTF8,0,str.c_str(),-1,NULL,0); wchar_t * pUnicode; pUnicode = new wchar_t...
