system.text.json

问题 Is it possible to merge two json objects like this with System.Text.Json? Object 1 { id: 1 william: "shakespeare" } Object 2 { william: "dafoe" foo: "bar" } Result Object { id: 1 william: "dafoe" foo: "bar" } I am able to achieve it with newtonsoft.json like this var obj1 = JObject.Parse(obj1String); var obj2 = JObject.Parse(obj2String); obj1.Merge(obj2); result = settings.ToString(); But is there a way with System.Text.Json ? 回答1: As of .Net Core 3.0 merging of JSON objects is not

问题 I have json that looks like this, the key "123" could be any number. { "key1": "", "key2": { "items": { "123": { "pageid": 123, "name": "data" } } } } I want to deserialize or query the json with System.Text.Json so i can get the value of the key "name". How can I do that with System.Text.Json? I'm using .NET Core 3.1. 回答1: Something like: public class Rootobject { public string key1 { get; set; } public InnerObject key2 { get; set; } } public class InnerObject { public Dictionary<string,

问题 I have the following situation. I have simplified the problem into the following example, although my real situation is more complicated. System.Text.Json does not serialise the object fully but Newtonsoft Json.NET does. Suppose I have the following class structure. public class A { public string AProperty { get; set; } = "A"; } public class A<T> : A where T : class, new() { public T TObject { get; set; } = new T(); } public class B { public string BProperty { get; set; } = "B"; } public

问题 The dotnet example in the documentation: https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-converters-how-to#support-polymorphic-deserialization shows manually parsing each property of a polymorphic type. However: my polymorphic objects are complex deep hierarchies, I can't hand code every field so I need to invoke the JsonSerializer . the clue for the type is specified in sibling fields. Given there is no guarantee about json element order, a Utf8JsonReader may
