如何格式化“dd/MM/yyyy”到日期？ c#.NetCore

Question

我试图在 Swagger 的示例 json 中显示日期格式“dd/MM/yyyy”。 但是，当我想展示它时，它会像这样向我展示：

{
  "contractCode": 0,
  "registers": 0,
  "totalDue1": 0,
  "totalDue2": 0,
  "buildingExpenses": [
    {
      "ownersAssociationCode": 0,
      "functionalUnitCode": 0,
      "period": "hola",
      "ownerName": "string",
      "location": "string",
      "ownerEmail": "string",
      "dueDate1": "2021-12-20T00:00:00",
      "amount1": 0,
      "amount2": 0,
      "electronicPaymentCode": "string",
      "barcode": "string"
    }
  ]
}

我尝试使用 parse 和 parseExact 对其进行格式化，但都没有成功。 我留下我的代码：public class BuildingExpenseModeExample: IExamplesProvider

{
    public object GetExamples()
    {
        var dueDate1 = DateTime.Now.ToString("dd/MM/yyyy");

        return new BuildingExpenseResumeInputDto
        {
            ContractCode = 0,
            Registers = 0,
            TotalDue1 = 0,
            TotalDue2 = 0,
            BuildingExpenses = new List<BuildingExpenseDetailInputDto>
            {
                new BuildingExpenseDetailInputDto
                {
                    OwnersAssociationCode = 0,
                    FunctionalUnitCode = 0,
                    Period = "hola",
                    OwnerName = "string",
                    Location = "string",
                    OwnerEmail = "string",
                    DueDate1 = DateTime.ParseExact(dueDate1, "dd/MM/yyyy", CultureInfo.InvariantCulture),
                    //DueDate1 = DateTime.ParseExact(DateTime.Today.ToString(), "dd/MM/yyyy", CultureInfo.InvariantCulture),
                    Amount1 = 0,
                    Amount2 = 0,
                    ElectronicPaymentCode = "string",
                    Barcode = "string"
                }
            }
        };
    }
}

我希望你能帮帮我！

最后，我能够通过将这两行代码添加到我的 Startup 来纠正它：

services.AddControllers().AddNewtonsoftJson(options =>
            {
                options.SerializerSettings.DateTimeZoneHandling = Newtonsoft.Json.DateTimeZoneHandling.Utc;
                options.SerializerSettings.DateFormatString = "dd/MM/yyyy";
            });

这样就解决了，因为在我的 api 中已经有一个 DateTimeConverter。 非常感谢大家！
