警告 CS0618：'IPAddress.Address' 已过时：'此 属性 已被弃用

Question

warning CS0618: 'IPAddress.Address' is obsolete: 'This property has been deprecated. It is address family dependent. Please use IPAddress.Equals method to perform comparisons.

将 IP 地址的八进制表示形式转换为无符号整数（包含在 long 中）。

public static long CastIp(string ip)
{
    return (long)(uint)IPAddress.NetworkToHostOrder((int)IPAddress.Parse(ip).Address);
}

它给了我这个警告；如果上面的代码中没有 IPAddress，我该怎么做才能完成同样的事情？

Answer 1

IPAddress.Address 的 documentation 说：

This property is obsolete. Use GetAddressBytes.

所以我建议你这样做：

public static long CastIp(string ip)
{
    IPAddress address = IPAddress.Parse(ip);
    byte[] addressBytes = address.GetAddressBytes();
    // This restriction is implicit in your existing code, but
    // it would currently just lose data...
    if (addressBytes.Length != 4)
    {
        throw new ArgumentException("Must be an IPv4 address");
    }
    int networkOrder = BitConverter.ToInt32(addressBytes, 0);
    return (uint) IPAddress.NetworkToHostOrder(networkOrder);
}

这似乎给出了相同的结果，在我试过的测试中......你应该检查它是否完全符合你的要求，因为它并不清楚你的期望。
