动态生成组件异常没有正常得到 Context对象

[杨柳]

环境 MacOS 10.13.5
工具 Visual Studio for mac
dotnet_2.1.301_x64

Windows 环境下是正常的。

Util.Logs 项目下 Log.cs 第89行。 var context = GetLogContext(); 动态生成组件异常没有正常得到 Context对象

我没有mac的环境呢，要不你修复一下提交一个issue上来？

这个问题是因为Util.Helpers.Web.GetLanIp()这个方法引发的异常。
我使用这个方法 @gerardo H https://stackoverflow.com/a/28621250/4861127

目前MacOS和Windows下是正常的。

private static string GetLanIp(NetworkInterfaceType _type = NetworkInterfaceType.Ethernet)
{
    try
    {
        foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
        {
            if (item.NetworkInterfaceType == _type && item.OperationalStatus == OperationalStatus.Up)
            {
                IPInterfaceProperties adapterProperties = item.GetIPProperties();
                if (adapterProperties.GatewayAddresses.FirstOrDefault() != null)
                {
                    foreach (UnicastIPAddressInformation ip in adapterProperties.UnicastAddresses)
                    {
                        if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
                        {
                            return ip.Address.ToString();
                        }
                    }
                }
            }
        }

    }
    catch
    {
        return string.Empty;
    }
    return string.Empty;
}
