Try this :

试试这个:

string url = HttpContext.Current.Request.Url.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx

string path = HttpContext.Current.Request.Url.AbsolutePath;
// /TESTERS/Default6.aspx

string host = HttpContext.Current.Request.Url.Host;
// localhost

You may at times need to get different values from URL.

您可能需要从URL获取不同的值。

Below example shows different ways of extracting different parts of URL

下面的示例展示了提取URL不同部分的不同方法

EXAMPLE: (Sample URL)

例如:(示例URL)

http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

http://localhost:60527 / WebSite1test / Default2.aspx ? QueryString1 = 1 &querystring2 = 2

CODE

代码

Response.Write("<br/> " + HttpContext.Current.Request.Url.Host);
Response.Write("<br/> " + HttpContext.Current.Request.Url.Authority);
Response.Write("<br/> " + HttpContext.Current.Request.Url.Port);
Response.Write("<br/> " + HttpContext.Current.Request.Url.AbsolutePath);
Response.Write("<br/> " + HttpContext.Current.Request.ApplicationPath);
Response.Write("<br/> " + HttpContext.Current.Request.Url.AbsoluteUri);
Response.Write("<br/> " + HttpContext.Current.Request.Url.PathAndQuery);

OUTPUT

输出

localhost
localhost:60527
60527
/WebSite1test/Default2.aspx
/WebSite1test
http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString1=2
/WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

You can copy paste above sample code & run it in asp.net web form application with different URL.

您可以复制上面的示例代码并在asp.net web表单应用程序中使用不同的URL运行它。

I also recommend reading ASP.Net Routing in case you may use ASP Routing then you don't need to use traditional URL with query string.

我也推荐阅读ASP。如果您可能使用ASP路由，那么不需要使用带有查询字符串的传统URL。

Just sharing as this was my solution thanks to Canavar's post.

多亏了Canavar的帖子，分享这一点是我的解决方案。

If you have something like this:

如果你有这样的东西:

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:

或者像这样:

"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:

你只需要用户输入的部分就可以了:

String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:

结果是:

"http://localhost:1234/"
"https://www.something.com/"

#4

if you just want the part between http:// and the first slash

如果您只想要http://和第一个斜杠之间的部分

string url = Request.Url.Host;

would return *.com if called from this page

如果从这个页面调用，会返回*.com吗

Here's the complete breakdown

这是完全崩溃

#5

the request.rawurl will gives the content of current page it gives the exact path that you required

请求。rawurl将给出当前页面的内容，它将给出所需的确切路径

use HttpContext.Current.Request.RawUrl

使用HttpContext.Current.Request.RawUrl

#6

If you want to get

如果你想要

localhost:2806

from

从

http://localhost:2806/Pages/

then use:

然后使用:

HttpContext.Current.Request.Url.Authority

#7

a tip for people who needs the path/url in global.asax file;

给需要全局路径/url的人的提示。asax文件;

If you need to run this in global.asax > Application_Start and you app pool mode is integrated then you will receive the error below:

如果需要在全局环境中运行。asax > Application_Start与您的app池模式集成后，您将收到以下错误:

Request is not available in this context exception in Application_Start.

在Application_Start的这个上下文异常中，请求不可用。

In that case you need to use this:

在这种情况下，您需要使用以下内容:

System.Web.HttpRuntime.AppDomainAppVirtualPath

System.Web.HttpRuntime.AppDomainAppVirtualPath

A search landed me at this page, but it wasn't quite what I was looking for. Posting here in case someone else looking for what I was lands at this page too.

我找到了这个页面，但它并不是我想要的。张贴在这里，以防有人寻找什么我是在这页。

There is two ways to do it if you only have a string value.

如果只有一个字符串值，有两种方法可以做到这一点。

.NET way:

net道:

Same as @Canavar, but you can instantiate a new Uri Object

与@Canavar相同，但是您可以实例化一个新的Uri对象

String URL = "http://localhost:1302/TESTERS/Default6.aspx";
System.Uri uri = new System.Uri(URL);

which means you can use the same methods, e.g.

也就是说你可以用同样的方法，例如

string url = uri.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx

string host = uri.host
// localhost

Regex way:

正则表达式:

Getting parts of a URL (Regex)

获取URL的一部分(Regex)

#9

I guess its enough to return absolute path..

2 .我想这足以补偿我的损失。

 Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;

使用先;
