Question

我正在学习vb.net并且想知道如何检查网站，如果它已经启动，设置公共共享，如果它已关闭，则使用不同的公共共享？

我目前的代码为

Public Shared domain As String = "domain"

但是当我启动应用程序然后运行检查时，我很困惑如何检查网站。

---编辑这就是我现在所拥有的，

Dim URL As String = "https://www.personalblog.com"

Public Shared Function IsWebpageOnline(ByVal URL As String) As Boolean
    Try
        Dim req As WebRequest = WebRequest.Create(URL)
        Dim res As WebResponse = req.GetResponse()
    Catch ex As Exception
        Return False
    End Try
    Return True
End Function

 If IsWebpageOnline = 1 Then
Public Shared domain As String = "blog.com"
 Else
Public Shared domain As String = "backupblog.com"
 End If

您可以使用此功能检查网页是否在线。

 Public Shared Function IsWebpageOnline(ByVal URL As String) As Boolean
       Try
            Dim req As WebRequest = WebRequest.Create(URL)
            Dim res As WebResponse = req.GetResponse()
       Catch ex As Exception
            Console.WriteLine(ex.Message)
            Return False
       End Try
    Return True
 End Function

它会尝试向Web服务器发出get请求，然后返回bool值

但我必须建议，尽早切换到C＃。

如何检查网站是否已启动？
