Unicode下char型数组转换CString问题

[hitwhzhongqiu]

char szTemp[10]="hello";
	CString m_string;
	m_string.Format(_T("%s"),szTemp);
	MessageBox(m_string);

总是会有乱码，请教如何正确显示

char szTemp[10]="hello"; CStringA m_string(szTemp); MessageBox(CString(m_string));

使用wcstombs

[信阳毛尖]

char szTemp[10]="hello"; CString m_string; m_string.Format(_T("%s"),CA2T(szTemp)); MessageBox(m_string); 或者使用MultiByteToWideChar转换吧

直接 char szTemp[10]="hello"; CString m_string(szTemp); 就可以了

CString已经为你做了一个 =号运算符重载. CString Str; char buf[0x100] = "这是文字"; Str = buf; 4楼的构造函数方式也可以

[tixisong]

CString ANSIToUnicode(char * szChar)
{
	int len = 0;
	len = MultiByteToWideChar(CP_ACP, 0, szChar, -1, NULL, 0);
	TCHAR * p;
	p = new TCHAR[len + 1];
	memset(p, 0, (len + 1) * sizeof(TCHAR));
	MultiByteToWideChar(CP_ACP, 0, szChar, -1, p, len);

	CString ss;
	ss.Format(_T("%s"), p);
	delete[]p;
	return ss;
}
string UnicodeToANSI(CString & szStr)
{
	int len = 0; 
	len = WideCharToMultiByte(CP_ACP, 0, szStr, -1, NULL, 0,NULL,NULL);

	char * pElementText;
	pElementText = new char[len + 1];
	memset(pElementText, 0, sizeof(len + 1));
	WideCharToMultiByte(CP_ACP, 0, szStr, -1, pElementText, len, NULL, NULL);

	string ss;
	ss = pElementText;
	delete[]pElementText;
	return ss;

}

// char转WCAHR  
void C2W(const char* szSrc, WCHAR* wszDst, int nMaxLen)
{
	int vMinLen = MultiByteToWideChar(CP_ACP, 0, szSrc, -1, NULL, 0);
	if(vMinLen > nMaxLen)
	{
		MessageBoxA(NULL, szSrc, "转换成UNICODE字串失败", MB_ICONWARNING);
		return;
	}
	MultiByteToWideChar(CP_ACP, 0, szSrc, -1, wszDst, vMinLen); 
}

// WCHAR转char 
void W2C(const WCHAR* wszSrc, char* szDst, int nMaxLen)
{
	int vMinLen = WideCharToMultiByte(CP_ACP, 0, wszSrc, -1, NULL, 0, NULL, FALSE);
	if(vMinLen > nMaxLen)
	{
		MessageBoxW(NULL, wszSrc, L"转换成ANSI字串失败", MB_ICONWARNING);
		return;
	}
	WideCharToMultiByte(CP_ACP, 0, wszSrc, -1, szDst, vMinLen, NULL, FALSE);
}

// char转WCAHR  
void C2W(const char* szSrc, WCHAR* wszDst, int nMaxLen/*wszDst的字符长度*/)
{
	int vMinLen = MultiByteToWideChar(CP_ACP, 0, szSrc, -1, NULL, 0);
	if(vMinLen > nMaxLen)
	{
		MessageBoxA(NULL, szSrc, "转换成UNICODE字串失败", MB_ICONWARNING);
		return;
	}
	MultiByteToWideChar(CP_ACP, 0, szSrc, -1, wszDst, vMinLen); 
}

// WCHAR转char 
void W2C(const WCHAR* wszSrc, char* szDst, int nMaxLen/*szDst的字符长度*/)
{
	int vMinLen = WideCharToMultiByte(CP_ACP, 0, wszSrc, -1, NULL, 0, NULL, FALSE);
	if(vMinLen > nMaxLen)
	{
		MessageBoxW(NULL, wszSrc, L"转换成ANSI字串失败", MB_ICONWARNING);
		return;

	WideCharToMultiByte(CP_ACP, 0, wszSrc, -1, szDst, vMinLen, NULL, FALSE);

6楼的不错。 改成智能指针更好。

谢谢大家了 很受用
