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。我想要拆分的网址是：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)

但我认为它不高效或可靠。我也不知道如何获得剩下的部分。

是否有更有效的方法来获取查询字符串？如何将URL拆分为我描述的部分？

使用内置类System.Uri，它可以自动为您完成所有解析：

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

使用Uri的实例，您应该能够轻松检索所有这些部分。

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
