c# System.Text.Json 反序列化Dictionarystring,object时未转换基础类型的处理方法

public class ObjectToInferredTypesConverter: JsonConverter<object>{public override object Read(ref Utf8JsonReader reader,Type typeToConvert,JsonSerializerOptions options){if (reader.TokenType == JsonTokenType.True){return true;}if (reader.TokenType == JsonTokenType.False){return false;}if (reader.TokenType == JsonTokenType.Number){if (reader.TryGetInt64(out long l)){return l;}return reader.GetDouble();}if (reader.TokenType == JsonTokenType.String){if (reader.TryGetDateTime(out DateTime datetime)){return datetime;}return reader.GetString();}// Use JsonElement as fallback.// Newtonsoft uses JArray or JObject.using JsonDocument document = JsonDocument.ParseValue(ref reader);return document.RootElement.Clone();}public override void Write(Utf8JsonWriter writer,object objectToWrite,JsonSerializerOptions options) =>throw new InvalidOperationException("Should not get here.");}//注入配置builder.AddJsonOptions(options =>{options.JsonSerializerOptions.Converters.Add(new ObjectToInferredTypesConverter());});
