推荐答案

否，不要拆分任何内容，也不要使用直接的字符串操作其他建议.

取而代之的是，首先使用System.IO.Path.GetDirectoryName提取目录.参见:

关于结果，请使用方法System.IO.Directory.GetParent所需次数，请参阅:
http://msdn.microsoft.com/en-us/library/system. io.directory.getparent.aspx [ ^ ].

与直接字符串操作(您很容易出错)不同，这些方法可靠且与平台无关.

No, don''t split anything and don''t use direct string manipulations as other advised.

Instead, first extract the directory using System.IO.Path.GetDirectoryName; see:
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx[^].

On the result, use the method System.IO.Directory.GetParent required number of times, see:
http://msdn.microsoft.com/en-us/library/system.io.directory.getparent.aspx[^].

Unlike direct string manipulations where you can easily make a mistake, these methods are reliable and platform independent.
