std::string的一些操作

將LPCTSTR轉換為std::string

LPCTSTR folder_path;char   str[1024]; wsprintfA(str, "%S ",folder_path); string str_(str);

去掉string的空格：

#include <iostream>#include <string>#include <boost/algorithm/string.hpp>using namespace std;using namespace boost;int main() {  string s = "  hello boost!! ";  trim(s);  cout << s << endl;}

string與wstring之間有轉換：

#include <string>#include <algorithm>// Prototype for conversion functionsstd::wstring StringToWString(const std::string& s);std::string WStringToString(const std::wstring& s);std::wstring StringToWString(const std::string& s){std::wstring temp(s.length(),L' ');std::copy(s.begin(), s.end(), temp.begin());return temp; }std::string WStringToString(const std::wstring& s){std::string temp(s.length(), ' ');std::copy(s.begin(), s.end(), temp.begin());return temp; }using namespace std;int main(){string s1 = "Hello";wstring s2 = StringToWString(s1);s1 = WStringToString(s2);return 0;}
