使用方法：
在form中调用GetSub就行了。
List1.AddItem ("公网IP:" GetSub + "..")。
VB.NET2010 怎么获取IP
1.获取当前电脑名：System.Net.Dns.GetHostName()
2.根据电脑名取出全部IP地址：System.Net.Dns.Resolve(电脑名).AddressList
或者 System.Net.Dns.GetHostByName(电脑名).AddressList
3.根据IP地址取出电脑名：System.Net.Dns.Resolve(IP地址).HostName
VB点虐 2015 如何获取外网IP并保存到软件目录下的IP.txt文件
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
Dim str As String
str = Me.WebBrowser1.Document.Body.InnerHtml
Dim a As Integer = 0
Dim b As Integer = 0
a = InStr(str, "[")
b = InStr(str, "]")
TextBox1.Text = Mid(str, a + 1, b - a - 1)
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.WebBrowser1.Navigate("
)
End Sub
End Class
网页上显示的有点问题，form1_load 中代码是：Me.WebBrowser1.Navigate("")
原理：访问查IP网页后，获取网页上显示的本机外网ip地址
