Path.Combine和点符号 [英] Path.Combine and the dot notation

问题描述

我正在寻找类似于 Path.Combine 的方法，这将有助于我正确地组合绝对路径和相对路径。例如，我想要

I'm looking for something akin to Path.Combine method that will help me correctly combine absolute and relative paths. For example, I want

Path.Combine(@"c:\alpha\beta", @"..\gamma");

以产生 c：\alpha\gamma 而不是 c：\alpha\..\gamma 作为 Path.Combine 。有没有办法完成这个？不用说，我也想要期限。路径或多个 .. 路径（例如， .. \..\ ）正常工作。

to yield c:\alpha\gamma instead of c:\alpha\..\gamma as Path.Combine does. Is there any easy way of accomplishing this? Needless to say, I also want to period . path or multiple .. paths (e.g., ..\..\) to work correctly.

推荐答案

使用 Path.GetFullPath

string path = Path.Combine(@"c:\alpha\beta", @"..\gamma");
Console.WriteLine(Path.GetFullPath(path));

或 DirectoryInfo 类：

string path = Path.Combine(@"c:\alpha\beta", @"..\gamma");
DirectoryInfo info = new DirectoryInfo(path);
Console.WriteLine(info.FullName);

都会输出：

c:\alpha\gamma
