什么是最小有效UNC路径? [英] What is a minimal valid UNC path?

问题描述

我想建立一个可以解析UNC路径的库，但是我对语法没有完全的了解.

I want to make a library that (among other things) parses UNC paths, but I don't fully understand the grammar.

常见示例为:\\server\share\path

所有这些都是有效文件路径所必需的吗?我可以使用Windows资源管理器导航到\\server(没有share)，但是我假设它正在使用某些共享发现协议，而文件系统API无法理解某些内容–是吗?

Are all of those required for a valid file path? I can navigate to \\server (without share) using Windows Explorer, but I assume it is using some share discovery protocol, not something filesystem APIs understand — is this right?

推荐答案

您是正确的.必须具有共享名称部分的UNC路径.

You are correct. A UNC path is required to have share name component.

引用MSDN:

UNC = \\<hostname>\<sharename>[\<objectname>]*

<hostname>，<sharename>和<objectname>被称为路径名组件"或路径组件".有效的UNC路径由两个或多个路径组成.

The <hostname>, <sharename>, and <objectname> are referred to as "pathname components" or "path components". A valid UNC path consists of two or more path components.
