英文:
How does the system go backward one path
问题
当前路径是 C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional
。
我如何将它设置为 C:\Users\USERNAME\OneDrive\Desktop\Pro
?
但我不想通过写字符串来设置它回去,我希望系统能够理解它所在的位置并向后移动。
简单来说,我希望它像 Windows 命令提示符中的 cd..
命令一样。
英文:
It's current path is C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional
How do i set it to C:\Users\USERNAME\OneDrive\Desktop\Pro
But I don't set by writing string to set it back I want the system to understand where it is and go backwards.
Simply put I want it to be like the cd..
command in Windows CMD.

获取当前目录,使用
var currentDirectory = Directory.GetCurrentDirectory();
要获取父目录,使用
var parentDirectory = Path.GetDirectoryName(currentDirectory);
最后,要设置当前目录:
Directory.SetCurrentDirectory(parentDirectory);
英文:
To get the current directory, use
var currentDirectory = Directory.GetCurrentDirectory();
To get the parent directory, use
var parentDirectory = Path.GetDirectoryName(currentDirectory);
And finally to set the current directory:
Directory.SetCurrentDirectory(parentDirectory);

System.IO
中有一个叫做 Path.GetDirectoryName
的方法。它会以你提供的路径作为输入,并返回该路径的父目录。
示例:
string path = "C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional";
string parentDirectory = Path.GetDirectoryName(path);
在这里,parentDirectory
现在包含 C:\Users\USERNAME\OneDrive\Desktop\Pro
。
如果你想向上多级,你可以多次调用;例如,
string path = @"C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional";
string parentDirectory = Path.GetDirectoryName(Path.GetDirectoryName(path));
parentDirectory
现在包含 C:\Users\USERNAME\OneDrive\Desktop
。
英文:
There is a method in System.IO
called Path.GetDirectoryName
. This would take your path as input and return the parent directory of the path which you have given.
Example:
string path = "C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional";
string parentDirectory = Path.GetDirectoryName(path);
Here, the parentDirectory
now contains C:\Users\USERNAME\OneDrive\Desktop\Pro
.
If you want to go up multiple levels, you can call multiple times; e.g.,
string path = @"C:\Users\USERNAME\OneDrive\Desktop\Pro\Professional";
string parentDirectory = Path.GetDirectoryName(Path.GetDirectoryName(path));
The parentDirectory
now contains C:\Users\USERNAME\OneDrive\Desktop
.
