我有JSON字符串,类似于:
{"1":{"1":"driver","2":"New York, NY"},"2":{"3":"male","2":"Alabama"}}
我有两个枚举:
public enum StoragePrimaryKeys
{
Login = 1,
Account = 2
};
public enum StorageSecondaryKeys
{
JobTitle = 1,
JobId = 2,
JobLocation = 3,
RenewDate = 4,
ExpirationDate = 5
};
如何将此JSON反序列化为对象?
我想做下一件事:
var jss = new JavaScriptSerializer();
Dictionary<string, string> sData = jss.Deserialize<Dictionary<string, string>>(value);
string output = string.empty;
foreach (KeyValuePair<string, string> entry in sData)
{
if (Convert.ToInt32(entry.Key) == StorageSecondaryKeys.JobTitle) {
}
output += "\n key:" + entry.Key + ", value:" + entry.Value;
}
但也许有更有效的方式?
我认为这是一个新问题,因为我的密钥中的数字应该转换为枚举字符串
感谢。

您的数据模型似乎应如下所示:
Dictionary<StoragePrimaryKeys, Dictionary<StorageSecondaryKeys, string>>
然而,从实验中,我发现JavaScriptSerializer
不支持枚举作为字典键,因此您无法直接反序列化为此类对象。因此,您可以反序列化为字符串键控字典并使用Linq转换:
var dict = new JavaScriptSerializer().Deserialize<Dictionary<string, Dictionary<string, string>>>(value)
.ToDictionary(
p => (StoragePrimaryKeys)Enum.Parse(typeof(StoragePrimaryKeys), p.Key),
p => p.Value.ToDictionary(p2 => (StorageSecondaryKeys)Enum.Parse(typeof(StorageSecondaryKeys), p2.Key), p2 => p2.Value));
这将生成您想要的词典。
或者,您可以安装json.net并直接反序列化到所需的字典,因为Json.NET确实支持枚举词典:
var dict = JsonConvert.DeserializeObject<Dictionary<StoragePrimaryKeys, Dictionary<StorageSecondaryKeys, string>>>(value);
