C++里stringchar*CString之间的转换

Posted 2022-12-06 sanqima

1、string 转 char*

 string strA = "hello";
 char*   pCh = strA.c_str();

2、string 转 wstring

    string  strA = "hello";
    wstring wStr = wstring(strA.begin(), strA.end());
    wcout << "wStr=" << wStr << endl;

3、wstring 转 string

    wstring wStr = L"world";
    string  strA = string(wStr.begin(), wStr.end());
    cout << "strA=" << strA << endl;

4、string 转 CString

string  strA = "hello";
CString sz(strA.c_str());

5、wstring 转 CString

wstring  strW = "hello";
CString sz(strW.c_str());

6、CString 转 string

//1) 方法一
CString sz = "hello";
string strA(CW2A(sz.GetString()));

//2) 方法二
CString szTwo = "hello";
string strB(CT2A(szTwo.GetString()));

//3) 方法三
CString szThr = "hello";
CStringA szA = szThr; //通过CStringA进行桥接
string strC = szA.GetString();

7、CString 转 wstring

//1) 方法一
CString sz = "hello";
Wstring strA(CA2W(sz.GetString()));

//2) 方法二
CString szTwo = "hello";
Wstring strB(CT2W(szTwo.GetString()));
