这可以通过JsonConverter为您的supplierData班级定做来解决。这是转换器的外观：
class supplierDataConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(supplierData));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JToken token = JToken.Load(reader);
if (token.Type == JTokenType.Object)
{
return token.ToObject<supplierData>();
}
return null;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
serializer.Serialize(writer, value);
}
}
要使用它，你需要做的是添加[JsonConverter]到属性supplier你的财产Data类是这样的：
public class Data
{
[JsonProperty("supplier")]
[JsonConverter(typeof(supplierDataConverter))]
public supplierData supplier { get; set; }
}
下面是运行中的转换器的演示。请注意，该演示假定您具有该data属性的某种包含对象，因为问题中的JSON不能独立存在。我RootObject为此定义了一个类：
public class RootObject
{
[JsonProperty("data")]
public Data Data { get; set; }
}
实际的演示代码如下：
class Program
{
static void Main(string[] args)
{
string json = @"
{
""data"":
{
""supplier"":
{
""id"": 15,
""name"": ""TheOne""
}
}
}";
Console.WriteLine("--- first run ---");
RootObject obj = JsonConvert.DeserializeObject<RootObject>(json);
Dumpsupplier(obj.Data.supplier);
json = @"
{
""data"":
{
""supplier"": false
}
}";
Console.WriteLine("--- second run ---");
obj = JsonConvert.DeserializeObject<RootObject>(json);
Dumpsupplier(obj.Data.supplier);
}
static void Dumpsupplier(supplierData supplier)
{
if (supplier != null)
{
Console.WriteLine("Id: " + supplier.Id);
Console.WriteLine("Name: " + supplier.Name);
}
else
{
Console.WriteLine("(null)");
}
Console.WriteLine();
}
}
这是上面的输出：
--- first run ---
Id: 15
Name: TheOne
--- second run ---
(null)
