c# Newtonsoft.Json转System.Text.Json

Question

这段代码是 Newtonsoft.Json 的 转成 System.Text.Json 改怎么写

    static readonly  JsonSerializerSettings? mSettings = CreateSettings();
    static JsonSerializerSettings CreateSettings(bool camelCase = true, bool indented = false)
    {
        var settings = JsonSerializerSettingsProvider.CreateSerializerSettings();
        settings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
        settings.FloatParseHandling = FloatParseHandling.Decimal;
        settings.Formatting = indented ? Formatting.Indented : Formatting.None;
        settings.Converters.Add(new TimeOnlyConverter());
        if (camelCase)
        {
            settings.ContractResolver = new CamelCaseMultiplePropertyContractResolver();
        }
        else
        {
            settings.ContractResolver = new MultiplePropertyContractResolver();
        }

        return settings;
    }

Answer 1

using System.Text.Json;

static readonly JsonSerializerOptions? mOptions = CreateOptions();
static JsonSerializerOptions CreateOptions(bool camelCase = true, bool indented = false)
{
    var options = new JsonSerializerOptions();
    options.PropertyNamingPolicy = camelCase ? JsonNamingPolicy.CamelCase : null;
    options.WriteIndented = indented;
    options.Converters.Add(new TimeOnlyConverter());
    // 在这你添加实现 ContractResolver

    return options;
}
