字段值

示例

以下示例使用 None 属性来指示不应使用任何网络接口。

public static void Main()
{
   // Gets the IP address indicating that no network interface should be used
   // and converts it to a string.
   string address = IPAddress.None.ToString();
   Console.WriteLine("IP address : " + address);
}

Public Shared Sub Main()

    ' Gets the IP address indicating that no network interface should be used
    ' and converts it to a string. 
    Dim address As String = IPAddress.None.ToString()
    Console.WriteLine(("IP address : " + address))
End Sub

注解

Socket.Bind方法使用 None 字段来指示 Socket 不得侦听客户端活动。 字段 None 等效于虚四表示法中的 255.255.255.255。
