std::string的一些操作
将LPCTSTR转换为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与wstring之间有转换:
#include <string> #include <algorithm> // Prototype for conversion functions std::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; }
