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

Question

>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}"

一个发送到我正在尝试反序列化的服务器，如下所示：

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

我遇到了一个错误：

"无法将字符串转换为日期时间：13/02/2014。路径 '交货日期'，第 1 行，位置 323。

由于日期有效，我假设这是非美国格式的问题。事实上，我知道这是因为如果我每天做的少于 13 次，它就会很好地反序列化。那么我如何指示反序列化程序使用非美国日期呢？

尝试使用 IsoDateTimeConverter 专门指定DateTime格式，并将其传递给 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);
