JsonConverter 不会用破折号（连字符）转换枚举

Question

我正在尝试使用 .NET Core (5) System.Text.Json JsonSerializer.Deserialize() 将 JSON 对象转换为 C# class，但它抛出了 JsonException .我相信原因是因为它试图转换为枚举的字符串值包含破折号（连字符）。枚举如下所示：

    [JsonConverter(typeof(JsonStringEnumConverter))]
    public enum TypeEnum
    {
        [EnumMember(Value = "loopback")]
        Loopback = 1,

        [EnumMember(Value = "link-local")]
        LinkLocal = 2,
    }

JSON 对象相当大，但导致异常的部分是：

{
    "address": "fe80::3617:ebff:fec0:b54c/64"
    "family": "inet6",
    "type": "link-local"
}

当 JsonSerializer 遇到 "type":"link-local" 时，它不喜欢 "link-local" 并抛出。有什么办法可以解决这个问题吗？

谢谢。

被要求例外，所以这里是：

 System.Text.Json.JsonException : The JSON value could not be converted to DmIfInfoAddr+TypeEnum. Path: $[0].addrs[0].type | LineNumber: 0 | BytePositionInLine: 144.

截至目前，System.Text.Json 不支持 System.Runtime.Serialization 属性，您可以在从 Newtonsoft.Json guide. There is an issue on github which you can track. As workaround you can try to use JsonStringEnumMemberConverter from Macross.Json.Extensions.
