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

问题描述

我在找一个类似于 Path.Combine 的方法，这将有助于我正确地结合绝对和相对路径。例如，我想

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");

得 C：\阿尔法\伽玛而不是 C：\阿尔法\ .. \伽玛为 Path.Combine 一样。有没有实现这一点有没有简单的方法？不用说，我也想时期。路径或多个 .. 路径（例如， .. \ .. \ ）才能正常工作。

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<一个href="http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx"><$c$c>Path.GetFullPath

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

或<一href="http://msdn.microsoft.com/en-us/library/system.io.directoryinfo.aspx"><$c$c>DirectoryInfo类：

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

双方将输出：

Both will output:

c:\alpha\gamma
