多字节和宽字节字符串的转换

使用MultiByteToWideChar函数和WideCharToMultiByte函数可以实现多字节宽字节之间的转换。ATL的一个很好的字符串的转换宏：A2W和W2A，使用起来更加简单。

一、MultiByteToWideChar和WideCharToMultiByte函数

#include <string> 
#include <windows.h> 
using namespace std; 
//Converting a WChar string to a Ansi string 
std::string WChar2Ansi(LPCWSTR pwszSrc) 
{ 
         int nLen = WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, NULL, 0, NULL, NULL); 
         if (nLen<= 0) return std::string(""); 
         char* pszDst = new char[nLen]; 
         if (NULL == pszDst) return std::string(""); 
         WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, pszDst, nLen, NULL, NULL); 
         pszDst[nLen -1] = 0; 
         std::string strTemp(pszDst); 
         delete [] pszDst; 
         return strTemp; 
}
string ws2s(wstring& inputws) 
{ 
        return WChar2Ansi(inputws.c_str()); 
}
//Converting a Ansi string to WChar string 
std::wstring Ansi2WChar(LPCSTR pszSrc, int nLen) 
{ 
    int nSize = MultiByteToWideChar(CP_ACP, 0, (LPCSTR)pszSrc, nLen, 0, 0); 
    if(nSize <= 0) return NULL; 
         WCHAR *pwszDst = new WCHAR[nSize+1]; 
    if( NULL == pwszDst) return NULL; 
    MultiByteToWideChar(CP_ACP, 0,(LPCSTR)pszSrc, nLen, pwszDst, nSize); 
    pwszDst[nSize] = 0; 
    if( pwszDst[0] == 0xFEFF)                    // skip Oxfeff 
        for(int i = 0; i < nSize; i ++) 
                            pwszDst[i] = pwszDst[i+1]; 
    wstring wcharString(pwszDst); 
         delete pwszDst; 
    return wcharString; 
}
std::wstring s2ws(const string& s) 
{ 
     return Ansi2WChar(s.c_str(),s.size()); 
}

二、MultiByteToWideChar和WideCharToMultiByte函数

std::wstring AsciiToUnicode(const std::string& str)
{
    // 预算-缓冲区中宽字节的长度  
    int unicodeLen = MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, nullptr, 0);
    // 给指向缓冲区的指针变量分配内存  
    wchar_t *pUnicode = (wchar_t*)malloc(sizeof(wchar_t)*unicodeLen);
    // 开始向缓冲区转换字节  
    MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, pUnicode, unicodeLen);
    std::wstring ret_str = pUnicode;
    free(pUnicode);
    return ret_str;
}
 
std::string UnicodeToUtf8(const std::wstring& wstr)
{
    // 预算-缓冲区中多字节的长度  
    int ansiiLen = WideCharToMultiByte(CP_UTF8, 0, wstr.c_str(), -1, nullptr, 0, nullptr, nullptr);
    // 给指向缓冲区的指针变量分配内存  
    char *pAssii = (char*)malloc(sizeof(char)*ansiiLen);
    // 开始向缓冲区转换字节  
    WideCharToMultiByte(CP_UTF8, 0, wstr.c_str(), -1, pAssii, ansiiLen, nullptr, nullptr);
    std::string ret_str = pAssii;
    free(pAssii);
    return ret_str;
}
 
//ANSI转UTF8
std::string AsciiToUtf8(const std::string& str)
{
    return UnicodeToUtf8(AsciiToUnicode(str));
}
 
//UTF8转ANSI
std::string Utf8toAscii(const std::string strUTF8)
{
    std::string  strAnsi = "";
    //获取转换为多字节后需要的缓冲区大小，创建多字节缓冲区
    UINT nLen = MultiByteToWideChar(CP_UTF8, NULL, strUTF8.c_str(), -1, NULL, NULL);
    WCHAR *wszBuffer = new WCHAR[nLen + 1];
    nLen = MultiByteToWideChar(CP_UTF8, NULL, strUTF8.c_str(), -1, wszBuffer, nLen);
    wszBuffer[nLen] = 0;
    nLen = WideCharToMultiByte(936, NULL, wszBuffer, -1, NULL, NULL, NULL, NULL);
    CHAR *szBuffer = new CHAR[nLen + 1];
    nLen = WideCharToMultiByte(936, NULL, wszBuffer, -1, szBuffer, nLen, NULL, NULL);
    szBuffer[nLen] = 0;
    strAnsi = szBuffer;
    //清理内存
    delete[]szBuffer;
    delete[]wszBuffer;
    return strAnsi;
}

三、A2W、W2A、A2T、T2A的使用方法
类型T。如果定义了 _UNICODE，则T表示W；如果定义了 _MBCS，则T表示A
头文件包含
#include <atlbase.h>

//（1）A2W的用法
USES_CONVERSION;   // 只需要调用一次，就可以在函数中进行多次转换
CString tmpStr;  
char*LineChar="fdsfdsa";  
const WCHAR * cLineChar = A2W(LineChar);  
tmpStr=cLineChar;  
//获取字符个数
wcslen(cLineChar );

W2A的用法：

USES_CONVERSION;  
CString tmpStr;  
WCH LineChar="fdsfdsa";  
const char* cLineChar = A2W(LineChar);  

A2T的用法：

USES_CONVERSION;  
char * pChar="char to cstring";  
CString cTemp=A2T(pChar);  

T2A的用法：

USES_CONVERSION;  
CString cTemp =_T("char to cstring");  
char * pChar=T2A(cTemp.GetBuffer(cTemp.GetLength())); 

四、几种ANSI和UNICODE的宏定义

L 在字符串前加一个L，如 L”我的字符串” 表示将ANSI字符串转换成unicode的字符串，就是每个字符占用两个字节。

strlen(L”asd”) = 6;

_T宏可以把一个引号引起来的字符串，根据你的环境设置，使得编译器会根据编译目标环境选择合适的（Unicode还是ANSI）字符处理方式。

TEXT,_TEXT 和_T 一样的。

std兼容字符串定义

 

#ifdef _UNICODE  
#define tstring std::wstring  
#else  
#define tstring std::string  
#endif

 

long int strtol(const char *str, char **endptr, int base) 把参数 str 所指向的字符串根据给定的 base 转换为一个长整数（类型为 long int 型），base 必须介于 2 和 36（包含）之间，或者是特殊值 0。

 

实例：

#include <stdio.h>
#include <stdlib.h>
int main()
{
   char str[30] = "2030300 This is test";
   char *ptr;
   long ret;
   ret = strtol(str, &ptr, 10);
   printf("数字（无符号长整数）是 %ld\n", ret);
   printf("字符串部分是 |%s|", ptr);
   return(0);
}

结果：

 

数字（无符号长整数）是 2030300

字符串部分是 | This is test|
