根据类型反序列化json字符串 [英] deserialize json string depending on type
本文介绍了根据类型反序列化json字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
具有这样的json字符串(我无法控制发布者):
Having json strings like this (I have no control over the publisher):
{
"TypeName": "Type1"
}
{
"TypeName": "Type1"
}
这是一种动态地反序列化json字符串的可接受方法吗?:
Is this an acceptable way to deserialize the json strings dynamically?:
public class DeserializationFactory
{
public static IPoco GetEvent(string jsonString)
{
var o = JObject.Parse(jsonString);
IPoco poco = null;
switch (o["TypeName"].ToString())
{
case "Type1":
poco = JsonConvert.DeserializeObject<Type1>(jsonString);
break;
case "Type2":
poco = JsonConvert.DeserializeObject<Type2>(jsonString);
break;
}
return poco;
}
}
推荐答案
您可以尝试 JsonSubtypes 转换器实现和此布局:
You can try with JsonSubtypes converter implementation and this layout:
[JsonConverter(typeof(JsonSubtypes), "TypeName")]
[JsonSubtypes.KnownSubType(typeof(Type1), "Type1")]
[JsonSubtypes.KnownSubType(typeof(Type2), "Type2")]
public interface IPoco
{
string TypeName { get; }
}
public class Type1 : IPoco
{
public string TypeName { get; } = "Type1";
/* ... */
}
public class Type2 : IPoco
{
public string TypeName { get; } = "Type2";
/* ... */
}
