使用非美国日期格式时,JsonConvert.DeserializeObject无法将字符串转换为DateTime

json

我有以下序列化的json对象:

"{\"LineItems\":[{\"LineID\":1,\"QuoteID\":\"00000000-0000-0000-0000-000000000000\",\"Quantity\":\"1\",\"UnitPriceExTax\":\"2\",\"UnitPriceTaxRate\":\"2\",\"UnitPriceTaxAmt\":0,\"LineTotalExTax\":2,\"LineTotalTaxAmt\":0.040000000000000036,\"LineTotalIncTax\":2.04}],\"QuoteID\":[],\"CurrencyID\":\"2\",\"SupplierRef\":\"SDFSFSDF\",\"DeliveryDate\":\"22/02/2014\",\"QuoteAvailablityStartDate\":\"13/02/2014\",\"QuoteAvailablityEndDate\":\"09/02/2014\",\"OpeningComments\":\"WWSFSFS \",\"PricingComments\":\"XSDFSDF \",\"DeliveryComments\":\"SDFSFSDF SDFSFSF\",\"TermsComments\":\"SFSFSDF SDFSFSDF SDFS\",\"FreightExTax\":\"1\",\"FreightExTax2\":1,\"FreightTaxRate\":\"1\",\"FreightTaxAmt\":0.010000000000000009,\"FreightIncTax\":1.01,\"TotalLinesExTax\":2,\"TotalLinesTaxAmt\":0.040000000000000036,\"TotalExTax\":3,\"TotalTaxAmt\":0.050000000000000044,\"TotalIncTax\":3.05}"

将其发送到我要反序列化的服务器,如下所示:

var json = Request.RequestContext.HttpContext.Request.Params["EoiDraftModel"];
var ld = JsonConvert.DeserializeObject<EoiDraftViewModel>(json);

我碰到一个错误:

“无法将字符串转换为DateTime:13/02/2014。路径’DeliveryDate’,第1行,位置323。”

由于日期是有效的,所以我假设它是非美国格式的问题。实际上,我知道这是因为如果我一天的工作量少于13,那么反序列化就可以了。那么如何指示反序列化器使用非美国日期?

尝试DateTime使用专门指定格式IsoDateTimeConverter,然后将其传递给JsonConvert.DeserializeObject<>()方法。

...
var json = Request.RequestContext.HttpContext.Request.Params["EoiDraftModel"];

var format = "dd/MM/yyyy"; // your datetime format
var dateTimeConverter = new IsoDateTimeConverter { DateTimeFormat = format };

var ld = JsonConvert.DeserializeObject<EoiDraftViewModel>(json, dateTimeConverter);
