json.net

问题 Fundamentally, I want to include or omit a property from the generated Json based on its value at the time of serialization. More-specifically, I have a type that knows if a value has been assigned to it and I only want to serialize properties of that type if there has been something assigned to it (so I need to inspect the value at runtime). I'm trying to make it easy for my API to detect the difference between "has the default value" and "wasn't specified at all". A custom JsonConverter

问题 I am attempting to deserialize a piece of JSON with a specific structure like so: { "label1": "value1", "label2": [ [ [ "concept_id_1", "concept_1" ], score_1 ], [ [ "concept_id_2", "concept_2" ], score_2 ], …… ], "label3": "value3", "label4": "value4" } For what it's worth, the scores are floats and everything else is a string. The number of returned concepts under "label2" is variable. I'm attempting to deserialize it using JSON.net. The only content I actually care about is the inside nest

问题 I am upgrading an application from .NET Core 2.2 to .NET Core 3.0, and the new System.Text.Json serializer is not behaving the same as Newtonsoft did in 2.2. On characters like a non-breaking-space (\u00A0) or emoji characters, Newtonsoft (and even Utf8Json) serialize them as their actual characters, not the Unicode code. I've created a simple .NET Fiddle to show this. var input = new Foo { Bar = "\u00A0 Test !@#$%^&*() 💯\uD83D\uDCAF 你好" }; var newtonsoft = Newtonsoft.Json.JsonConvert
