Question

我有一个包含属性“Data”的对象。此属性以Json格式保存其他元数据。

但是，我现在需要将整个对象作为Json字符串发送到网页。我正在使用带有以下代码的.Net Core 2.0

未捕获的SyntaxError：位于3159的JSON中的意外的令牌i 在JSON.parse（）

如何确保我的Data属性在实际需要之前不被视为Json（在这种情况下，我将使用JQuery对我需要的位进行反序列化）

我正在返回的Json字符串看起来像是

services.AddMvc().AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());

显然我有引用问题.....

由于
