我有一个相当大的 JSON 对象，我已使用 this post 中表示的方法在 c# 中将其转换为动态对象。需要说明的是，我使用的是寄存器序列化程序方法，而不是 MVC 库中的方法。
我可以很好地读取这些值；但是，我希望能够用新信息更新它们。每次我尝试时，程序都会崩溃，但没有太多关于原因的信息。有没有办法在不使用数据契约创建新类的情况下做到这一点？
如何将值写入此动态对象？
编辑
我一定是错误地引用了对象的值，因为我收到了 "{"'System.Dynamic.DynamicObject' does not contain a definition for 'password'"}" 错误消息。
这是JSON

这是我正在运行的
// register converter
serializer.RegisterConverters(new[] { new DynamicJsonConverter() });
dynamic obj = serializer.Deserialize(result, typeof(object));
obj.userParameters.authenticationConfig.accounts[0].password = "testing";
最佳答案
通过包含您在上一篇文章中使用的序列化程序，我能够重现您的问题。我想出了问题所在:
That Serializer 是只读的，因为 DynamicJsonObject 类没有实现 TrySetMember 方法，因此它默认为 DynamicObject 中的基方法。因此，它不支持值的“设置”。但这很容易补救。您所要做的就是将以下方法添加到 DynamicJsonConverter.cs 文件中的 DynamicJsonObject 类:
public override bool TrySetMember(SetMemberBinder binder, object value)
{
_dictionary[binder.Name] = value;
return true;
}
进行更改后，我确认这可以解决问题，您将能够根据您的示例设置任何值。
