示例1: notation

Try

    ' dotted-quad notation (for example, "www.contoso.com" or "207.46.131.199") to 
    ' obtain an IPHostEntry instance that contains address information for the 
    ' specified host.
    Dim hostInfo As IPHostEntry = Dns.Resolve(hostString)
    ' Get the IP address list that resolves to the host names contained in the Alias 
    ' property.
    Dim address As IPAddress() = hostInfo.AddressList
    ' Get the alias names of the addresses in the IP address list.
    Dim [alias] As [String]() = hostInfo.Aliases

    Console.WriteLine(("Host name : " + hostInfo.HostName))
    Console.WriteLine(ControlChars.Cr + "Aliases : ")
    Dim index As Integer
    For index = 0 To [alias].Length - 1
        Console.WriteLine([alias](index))
