Try this :
尝试这个 ：
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
回答by roman m
if you just want the part between http:// and the first slash
如果你只想要 http:// 和第一个斜杠之间的部分
string url = Request.Url.Host;
would return stackoverflow.com if called from this page
如果从此页面调用，将返回 stackoverflow.com
Here's the complete breakdown
这是完整的细分

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.
搜索使我进入了这个页面，但这并不是我想要的。在这里发帖以防其他人也在此页面上寻找我的内容。
There is two ways to do it if you only have a string value.
如果您只有一个字符串值，有两种方法可以做到。
.NET way:
.NET方式：
Same as @Canavar, but you can instantiate a new Uri Object
与@Canavar 相同，但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.
这意味着您可以使用相同的方法，例如
string url = uri.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx
string host = uri.host
// localhost
Regex way:
正则表达式方式：

Just sharing as this was my solution thanks to Canavar's post.
只是分享，因为这是我的解决方案，感谢 Canavar 的帖子。
If you have something like this:
如果你有这样的事情：
"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:
并且您只需要用户输入的部分，然后这将起作用：
String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");
which would result in these:
这将导致这些：
"http://localhost:1234/"
"https://www.something.com/"

I guess its enough to return absolute path..
我想它足以返回绝对路径..
Path.GetFileName( Request.Url.AbsolutePath )
using System.IO;
使用 System.IO；

如果你想得到
localhost:2806
from
从
http://localhost:2806/Pages/

HttpContext.Current.Request.Url.Authority

You may at times need to get different values from URL.
您有时可能需要从 URL 获取不同的值。
Below example shows different ways of extracting different parts of URL
下面的示例显示了提取 URL 不同部分的不同方法
EXAMPLE:(Sample URL)
示例：（示例网址）
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.
您可以复制粘贴上面的示例代码并在具有不同 URL 的 asp.net Web 表单应用程序中运行它。
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.
我还建议您阅读 ASP.Net Routing，以防您可能使用 ASP Routing，然后您就不需要使用带有查询字符串的传统 URL。
