知识点：

CString转char*，string

string转char*,CString

char* 转CString,string

一、CString转char*，string

    //字串转换测试

    CString CString1;

    std::string string1;

    CHAR*  char1=NULL;

    //

    string1=CString1.GetBuffer();

    CString1.ReleaseBuffer();

    //

    char1=CString1.GetBuffer();

    CString1.ReleaseBuffer();

二、string转char*,CString

    //

    CString1=string1.data();

    //

    char1=new CHAR[string1.length()+];

    strcpy(char1,string1.data());

三、CHAR* 转CStringwstring

        CString1=char1;

             string1=char1;

    //// TODO: 在此添加控件通知处理程序代码

    //CString CString1="CString";

    //std::string string1="string";

    //CHAR * char1="char1";

    ////一、CString 字串转string ,char*

    //string1=CString1;

    //char1=CString1.GetBuffer();

    //CString1.ReleaseBuffer();//释放掉字串缓冲区

    ////二、string 转CString char*

    //string1="string1";

    //CString1=string1.data();

    ////char1=string1.data();

    //new char[string1.length()+1];

    //strcpy(char1,string1.data());

    ////三、char* 转CString ,string

    //char1="char1";

    //CString1=char1;

    //string1=char1;

    //// TODO: 在此添加控件通知处理程序代码

    //CString CString1=L"CString";

    //std::wstring string1=L"string";

    //WCHAR * char1=L"char1";

    ////一、CString 字串转string ,char*

    //string1=CString1;

    //char1=CString1.GetBuffer();

    //CString1.ReleaseBuffer();//释放掉字串缓冲区

    ////二、string 转CString char*

    //string1=L"string1";

    //CString1=string1.data();

    ////char1=string1.data();

    //new WCHAR[string1.length()+1];

    //wcscpy(char1,string1.data());

    ////三、char* 转CString ,string

    //char1=L"char1";

    //CString1=char1;

    //string1=char1;

    // TODO: 在此添加控件通知处理程序代码

    CString CString1=  _T("CString");

    std::string string1=_T("string");

    TCHAR * char1=_T("char1");

    //一、CString 字串转string ,char*

    string1=CString1;

    char1=CString1.GetBuffer();

    CString1.ReleaseBuffer();//释放掉字串缓冲区

    //二、string 转CString char*

    string1=_T("string1");

    CString1=string1.data();

    //char1=string1.data();

    new TCHAR[string1.length()+];

    strcpy(char1,string1.data());

    //三、char* 转CString ,string

    char1=_T("char1");

    CString1=char1;

    string1=char1;
