将URL拆分为VB.Net的不同部分

Question

我想将URL拆分为不同的组件,类似于JavaScript中的location对象.我想要的部分是:哈希,主机,主机名,路径名,端口,协议和查询字符串.我要拆分的网址是:http://localhost:8080/settings/settings.php?setting=layout&value=normal#appearance.

目前,我有:

Dim url as String = "http://localhost:8080/settings/settings.php?setting=layout&value=normal#appearance"
Dim protocol as String = url.Split("://")(0)
Dim hash = url.Split("#")(1)
Dim query as String = url.Split("?")(1).Split("#")(0)

但我不认为它有效或可靠.我也不知道如何获得剩下的部分.

有更有效的方法来获取查询字符串吗？如何将URL拆分为我描述的部分？

使用内置类System.Uri,它可以自动为您执行所有解析:

Dim url as String = "http://localhost:8080/settings/settings.php?setting=layout&value=normal#appearance"
Dim uri as New Uri(url)

有了一个实例,Uri你应该能够轻松地检索所有这些部分.

Dim protocol as String = uri.Scheme     ' http
Dim host as String = uri.Host           ' localhost
Dim port as Integer = uri.Port           ' 8080
Dim path as String = uri.AbsolutePath   ' /settings/settings.php
Dim querystring as String = uri.Query   ' ?setting=layout&value=normal
Dim hash as String = uri.Fragment       ' #appearance
