C＃将JSON DynamicObject分配给一个类

Question

public class RootObject
{
    public List<Result> results { get; set; }
    public int result_index { get; set; }
}

...

private void ReadJson()
{
    string JsonString = File.ReadAllText(MyJsonFile);
    DynamicObject jObject = System.Web.Helpers.Json.Decode(JsonString);
    RootObject RO = (RootObject)jObject;
    ...
}

该行：

RootObject RO = (RootObject)jObject;

不正确。如何将DynamicObject分配给我的类？

Answer 1

您无法将DynamicObject分配给RootObject类型的变量，因为类型不是assignable。相反，您应该将JSON反序列化为RootObject，以便开始使用Json.Decode<T>：

var RO = System.Web.Helpers.Json.Decode<RootObject>(JsonString);
