本文主要解析cstring和int，double，char*之间的相互转换方法：

        cout<<"测试1：int to cstring"<<endl;int num=19;CString cstr;cstr.Format(_T("%4d"),num);wcout<<cstr.GetString()<<endl;cout<<"测试2：float to cstring"<<endl;float f1=19.3234876;cstr.Format(_T("%.2f"),f1);wcout<<cstr.GetString()<<endl;cout<<"测试3：double to cstring"<<endl;double d1=19.3234876;cstr.Format(_T("%.8lf"),d1);wcout<<cstr.GetString()<<endl;cout<<"测试4：16进制 to cstring"<<endl;int num2=10;cstr.Format(_T("%x"),num2);wcout<<cstr.GetString()<<endl;cout<<"测试5：char to cstring"<<endl;char ch[10]="中国ABC";cstr.Format(_T("%S"),ch);wcout<<cstr.GetString()<<endl;cout<<"测试6：cstring to int"<<endl;CString cstrnum=_T("9987");num=_ttoi(cstrnum);cout<<num<<endl;cout<<"测试7：cstrign to double"<<endl;CString cstrdou=_T("987.32673");double d2= _wtof(cstrdou);cout<<d2<<endl;cout<<"测试8：cstrign to char*"<<endl;cstr=L"你好ABc";string s=Unicode_To_Ansi(cstr.GetString());cout<<s<<endl;

CString转std::wstring

std::wstring str = filename.GetString();

std::wstring转CString

CString str( filename.c_str() );
