从包含文件名的路径中获取没有文件名的完整路径 [英] Get full path without filename from path that includes filename

问题描述

System.IO.Path 中是否有任何内置的东西只给我文件路径?

Is there anything built into System.IO.Path that gives me just the filepath?

例如，如果我有一个 string

For example, if I have a string

@"c:webserverpublicmyCompanyconfigspromo.xml",

@"c:webserverpublicmyCompanyconfigspromo.xml",

有什么BCL方法可以给我

is there any BCL method that will give me

"c:webserverpublicmyCompanyconfigs"?

"c:webserverpublicmyCompanyconfigs"?

推荐答案

Path.GetDirectoryName()... 但你需要知道你传递给它的路径确实包含文件名;它只是从路径中删除最后一位，无论是文件名还是目录名(它实际上不知道是哪个).

Path.GetDirectoryName()... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).

您可以首先通过在您的路径上测试 File.Exists() 和/或 Directory.Exists() 来验证是否需要调用 Path.GetDirectoryName

You could validate first by testing File.Exists() and/or Directory.Exists() on your path first to see if you need to call Path.GetDirectoryName
