C＃如何设置JsonProperty多个名称？

Question

[XmlElement("A", Type = typeof(MyModelA)), XmlElement("B", Type = typeof(MyModelB))] 
public List<object> context{ get; set; } 

能工作，但我想改变JsonProperty，这样

[JsonProperty("A", ItemConverterType = typeof(MyModelA)), JsonProperty("B", ItemConverterType = typeof(MyModelB))] 
public List<object> context{ get; set; } 

它失败了，我应该怎么办？

{ 
    node:{ 
     A:{ MyModelA } 
     B:{ MyModelB } 
     } 
}

您需要使用属性JsonExtensionData。试试这个：

public sealed class ModuleA 
{ 
    public string Foo { get; set; } 
} 
public sealed class ModuleB 
{ 
    public string Boo { get; set; } 
} 
public class Node 
{ 
    [JsonExtensionData] 
    public Dictionary<string, JToken> Context { get; set; } 
} 
public class Example 
{ 
    public Node Node { get; set; } 
} 

var moduleA = new ModuleA {Foo = "Hello from Module A"}; 
var moduleB = new ModuleB { Boo = "Hello from Module B" }; 
var example = new Example 
     { 
      Node = new Node 
      { 
       Context = new Dictionary<string, JToken> 
       { 
        {"A", JToken.FromObject(moduleA)}, 
        {"B", JToken.FromObject(moduleB)} 
       } 
      } 
     };   

结果：

{ 
"Node": { 
    "A": { 
     "Foo": "Hello from Module A" 
    }, 
    "B": { 
     "Boo": "Hello from Module B" 
    } 
}}
