用C#组合两个相对路径 [英] Combining two relative paths with C#

问题描述

将相对路径附加到绝对路径"有很多欺骗，但我需要添加相对于相对.

There are many dupes for "appending a relative path to an absolute path", but I need to add relative to relative.

例如:

Path1 = "Parent/Child/a.txt"
Path2 = "../Sibling/file.cs"

Result = "Parent/Sibling/file.cs"

尝试过:

---

Tried:

• Directory.GetParent() - 有效，但我找不到返回结果的方法(它只能返回绝对路径)
• Path.Combine() - 仅适用于简单情况和绝对路径.使用带有相对路径的.."失败(严重！)

• Directory.GetParent() - works, but I can't find a way to return the result (it can only return absolute paths)
• Path.Combine() - only works for simple cases and absolute paths. Fails (badly!) on the use of ".." with relative paths

...编写一个字符串标记的 Path 类来解决这个问题似乎很荒谬，但我一直在挖掘 MSDN 文档，似乎找不到一个可以正确处理相对路径的工作路径/目录类.

...it seems absurd to write a string-tokenizing Path class to solve this, but I've been digging through the MSDN docs and can't seem to find a working Path/Directory class that correctly works with relative paths.

更糟糕的是......我正在努力让这项工作一直回到 .NET 2(感谢 Mono 兼容性)

To make matters worse ... I'm trying to make this work all the way back to .NET 2 (thanks to Mono compatibilty)

推荐答案

我知道下面的代码很丑但可以工作(抱歉我还没有确认单声道):

I know the following code is ugly but will work (sorry I don't confirm on mono yet):

var Result =
    Path.GetFullPath(Path.Combine(Path.GetDirectoryName(Path1), Path2))
    .Substring(Directory.GetCurrentDirectory().Length + 1); // +1 to remove leading path separator
