C ++ - 转换std :: basic_string <char>

Question

Brace yourselves! C++ newbie question incoming:

Can someone explain to me why this error occurs and how should I fix it?

std::vector<std::string> options = vectorOGROptions_.get()

I want to get options var as std::vector<std::string> but it seems my vectorOGROptions property returns a different type..

error: conversion from ‘const std::basic_string<char>’ to non-scalar type ‘std::vector<std::basic_string<char> >’ requested

Answer 1

Your get() function returns string , but you are trying to initialize vector with this string, that's not allowed.

You can use something like this

std::vector<std::string> options;
options.push_back(vectorOGROptions.get());

Answer 2

You are trying to assign to a vector a string. You cannot do this. Use an initialiser list.

std::vector<std::string> options{vectorOGROptions_.get()};

Answer 3

The error says that this get() function returns const std::basic_string<char> , which is nothing but std::string . Use vector's push_back() method:

std::vector<std::string> options;
options.push_back(vectorOGROptions_.get());
