使用.NET DataContractJsonSerializer序列化程序使用Dictionary对JSON进行序列化
本文关键字:序列化 JSON Dictionary NET DataContractJsonSerializer 程序 使用 | 更新日期: 2023-09-27 18:27:19
首先。。我对JSON.NET或任何其他解析器都不感兴趣。仅DataContractJsonSerializer
我必须使用我获取并发送到REST API的结构,它们看起来是这样的:
{ "records": [
{
"attributes": {
"OBJECTID": 1,
"Address": "380 New York St.",
"City": "Redlands",
"Region": "CA",
"Postal": "92373"
}
},
{
"attributes": {
"OBJECTID": 2,
"Address": "1 World Way",
"City": "Los Angeles",
"Region": "CA",
"Postal": "90045"
}
}
]
我们能看到的是这样的东西:
class SomeData
{
public List<SomeRecord> Records { get; set; }
}
class SomeRecord
{
public List<KeyValuePair<string, string>> Attributes { get; set; }
}
我该如何为我的对象赋予属性,以便序列化程序能够生成这样的结构?或者我应该创建一个属性覆盖每个属性的对象吗?
问题是,这个Web服务似乎到处都是属性,我甚至不确定所有可能的名称。因此,KVP列表似乎是一个不错的选择,但它对我不起作用。
以下内容应该有效,
[DataContract]
[KnownType(typeof(Record))]
public class RecordList
{
public RecordList()
{
Records = new List<Record>();
}
[DataMember]
public List<Record> Records { get; set; }
}
public class Record
{
public Record()
{
Attributes = new AttributeList();
}
[DataMember]
public AttributeList Attributes { get; set; }
}
[Serializable]
public class AttributeList : DynamicObject, ISerializable
{
private readonly Dictionary<string, object> attributes = new Dictionary<string, object>();
public override bool TrySetMember(SetMemberBinder binder, object value)
{
attributes[binder.Name] = value;
return true;
}
public void GetObjectData(SerializationInfo info, StreamingContext context)
{
foreach (var kvp in attributes)
{
info.AddValue(kvp.Key, kvp.Value);
}
}
}
[Test]
public void TestSerialize()
{
var holder = new RecordList();
dynamic record = new Record();
record.Attributes.OBJECTID = 1;
record.Attributes.Address = "380 New York St.";
record.Attributes.City = "Redlands";
record.Attributes.Address = "Region";
record.Attributes.Region = "CA";
record.Attributes.Postal = "92373";
holder.Records.Add(record);
var stream1 = new MemoryStream();
var serializer = new DataContractJsonSerializer(typeof(RecordList));
serializer.WriteObject(stream1, holder);
stream1.Position = 0;
StreamReader sr = new StreamReader(stream1);
Console.Write("JSON form of holder object: ");
Console.WriteLine(sr.ReadToEnd());
}
