C＃-使用DataContractJsonSerializer将JSON字符串反序列化为Enum []

Question

I have this JSON string

[ \"postal_code\" ]

My enum definition:

[DataContract]
public enum MyEnum
{
    [EnumMember(Value = "postal_code")]
    PostalCode,
}

Here's what I've done so far:

byte[] byteArray = Encoding.ASCII.GetBytes(jsonString);
MemoryStream outputStream = new MemoryStream(byteArray);
DataContractJsonSerializer dataContractJsonSerializer = new DataContractJsonSerializer(typeof(MyEnum[]));
MyEnum[] myEnum = (MyEnum[]) dataContractJsonSerializer.ReadObject(outputStream);
outputStream.Close();
//return myEnum ;

I get an error upon reaching the ReadObject line

System.FormatException: Input string was not in the correct format: nDigits == 0.

How can I properly deserialize the JSON string to MyEnum?

I also want to avoid using JSON.Net. I'd want to go with DataContractJsonSerializer.

Answer 1

as you can read here .

Enumeration member values are treated as numbers in JSON, which is different from how they are treated in data contracts, where they are included as member names

Also

All enum members are serializable. The EnumMemberAttribute and the NonSerializedAttribute attributes are ignored if used.

So, try to use another deserializer for this purpose. Maybe JSON.net or extend the JsonSerializer as proposed here .
