c# - 有没有办法使用 Uri 类在 url 中保留点段？

Question

当我创建带有点段的 uri 时:

var uri = new Uri("http://localhost/../../g");

uri 类删除了 ../ 段，结果 uri 变为:

http://localhost/g

当点之前有路径时:

var uri = new Uri("http://localhost/a/b/c/./../../g");
// Result: http://localhost/a/g

看起来 Uri 类在 the standart 之后(第 33 页 - remove_dot_segments)，但是有什么方法可以保留点段而不是使用 Uri 自动解析目标 uri类(class)？还是我需要自定义实现？

如果您使用的是 HTTP，则不会，如果您使用 Uri 类，它总是会转义它们。它对以下所有内容进行转义:file、http、https、net.pipe 和 net.tcp

如果您使用的是 ftp 之类的东西，那么它不会转义，但听起来这不是您的选择。

来自 MSDN's documentation :

As part of canonicalization in the constructor for some schemes, escaped representations are compacted. The schemes for which URI will compact escaped sequences include the following: file, http, https, net.pipe, and net.tcp. For all other schemes, escaped sequences are not compacted. For example: if you percent encode the two dots ".." as "%2E%2E" then the URI constructor will compact this sequence for some schemes. For example, the following code sample shows a URI constructor for the http scheme.
