  This topic demonstrates how to convert various Visual C++ string types into other strings. The strings types that are covered include char *, wchar_t*, _bstr_t, CComBSTR, CString, basic_string, and System.String. In all cases, a copy of the string…

通过前一篇文章<C++中string,wstring,CString的基本概念和用法>,对Cstring.wstring 和string有了一个了解.string是C++提供的标准字符串操作类.wstring是操作宽字符串的类..CString是对string(字符串)和wstring(宽字符串)的一个封装,常用在mfc中,用来解决编码问题的.在编程过程中,经常会遇到Cstring.wstring 和string之间的相互转换,在这里做了个简单地总结,另外也会附上其他类型的转换.常见的转换方式…

1. CString  转 char* ); CString name; name.Format(_T("bookUC%d.txt"),m_ID); std::wstring _name=name; _bstr_t t = _name.c_str(); char* pchar = (char*)t; 2. wstring  转 string wstring ws; _bstr_t t = ws.c_str(); char* pchar = (char*)t; string result…

在VC++开发中,经常会用到string和wstring,这就需要二者之间的转换,项目中封装了wstring和string相互转换的2个函数,实现如下: //将wstring转换成string std::string ConvertWStringToAnsi(std::wstring wstr) { std::string result; int len = WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), wstr.size(), NULL, 0, NU…

个人倾向于使用优秀的开源库做这个. 最近使用boost进行转换,代码极其简单: boost::filesystem::path src(wchar_t); char = src.string().c_str(); 当然也支持wstring和string的转换…

通常 object 到 string 有四种方式(假设有object obj):obj.ToString().Convert.ToString().(string)obj.obj as string.他们都能将 object 对象转换成 string 对象.我就讲讲他们的异同以及在实际中应该使用哪个. 前两个方法通常是由别的对象得到 string 对象,它们间的区别只表现在要转换的对象为 null 时,如果 obj 为 null,调用 obj.ToString 方法会导致 NullReferen…

how convert large HEX string to binary I have a string with 14 characters . This is a hex represantation of 7bytes. I want to convert it to binary. int32_t Hex2Bin( uint8_t * pHexString, uint8_t * pBinArray ) { ; ; while ( pHexString[ i ] != 0x00 ) {…

How to convert a std::string to const char* or char*? 1. If you just want to pass a std::string to a function that needs const char* you can use std::string str; const char * c = str.c_str(); If you want to get a writable copy, like char *, you can d…
