创建开放的我们在.NET自动urlde codeS从传递的字符串的所有参数 [英] Creating an Uri in .NET automatically urldecodes all parameters from passed string

问题描述

假设我要创建以下字符串的Uri对象：

Suppose I want to create an Uri object from the following string:

string url = @"http://someserver.com?param1=1&url=http%3a%2f%2fwww.otherserver.com";
Uri uri = new Uri(url, UriKind.Absolute);

预期结果将是：

Expected result would be:

http://someserver.com?param1=1&url=http%3a%2f%2fwww.otherserver.com 

获得：

http://someserver.com/?param1=1&url=http://www.otherserver.com

同样的行为注意到，在许多相关的方法，使开放的创作：Uri.TryCreate，UriBuilder.Uri等

The same behavior is noticed in many related methods that allow Uri creation: Uri.TryCreate, UriBuilder.Uri, etc.

我将如何得到一个URI，它preserve初始连接codeD参数？

How would I get an Uri that preserve initial encoded parameter?

推荐答案

此行​​为的记载：

随着标准化在构造函数中的一些方案的一部分，   逃脱重新presentations被压缩。该计划为其URI将   小巧转义序列包括以下内容：文件，HTTP，HTTPS，   net.pipe和的net.tcp。对于所有其他方案，逃脱序列   不板结。例如：如果您％的EN code中的两个点..作为   ％2E％2E那么URI构造函数将压缩该序列的部分   计划。例如，下面的code示例显示了一个URI   构造http方案。

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.

所以，一个解决办法可能是暂时使用自定义方案（如 leavemealone：// ）来构造URL对象（可能通过 UriBuilder ？）。

So one workaround might be temporarily using a custom scheme (e.g. leavemealone://) to construct the URL objects (possibly through UriBuilder?).
