C ++ - ifstream不喜欢相对路径 [英] C++ - ifstream not liking relative paths

问题描述

使用ifstream

I have been having trouble with opening files with ifstream

打开文件时遇到问题：

ifstream myfile;
    myfile.open("C:/Users/build/windows/Debug/map1.xml");

它工作正常，但如果我做一个相对路径（可执行文件在Debug /）

it works fine, but if I do a relative path (the executable is in Debug/)

ifstream myfile;
    myfile.open("map1.xml");

找不到文件。任何帮助？

It will not find the file. Any help? Am I missing something silly?

推荐答案

很可能，您的IDE在启动时会更改程序的工作目录。尝试将 map1.xml 插入 c：\users\build\windows

Most likely, your IDE changes your program's working directory when launching it. Try putting map1.xml into c:\users\build\windows
