使用多个LINQ语句的SQL日期时间溢出

我遇到以下问题。使用多个LINQ语句的SQL日期时间溢出

在下面的代码块中，第一次通过if语句触发并且一切正常。第二次通过formData.Where发生SQL DateTime溢出错误。被撤回的值是一个字符串，与日期无关。正在引用的记录确实有一个日期，但它是当天。我已经改变了这些if语句触发的顺序，并且哪一个是第一个或第二个都没有关系。第二个总是抛出异常。

foreach (string riderGroup in riderGroups) 
      { 
       if (riderGroup == "69") 
       { 
        var deathRiderValue = formData.Where(x => x.FieldName == "rider69Value").Select(x => x.FieldValue).Single().ToString(); 
        var rider = _riderDataService.GetRiderById(Convert.ToInt32(deathRiderValue)); 
        premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy });       
       } 
       if (riderGroup == "211") 
       { 
        var gmabRiderValue = formData.Where(x => x.FieldName == "rider211Value").Select(x => x.FieldValue).Single().ToString(); 
        var rider = _riderDataService.GetRiderById(Convert.ToInt32(gmabRiderValue)); 
        premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy }); 
       } 
       if (riderGroup == "96") 
       { 
        var giveawayPromoValue = formData.Where(x => x.FieldName == "rider96Value").Select(x => x.FieldValue).Single().ToString(); 
        if (giveawayPromoValue == "1") 
        { 
         var rider = _riderDataService.GetRiderById(5); 
         premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy }); 
        } 
       } 
      }

任何想法？

你是什么意思'DateTime overflow'？所有这些代码中使用了“DateTime”的位置？什么是*实际*错误？ 'datetime'字段不允许存储无效值，那么如何溢出？你是否将日期存储为字符串，并试图将它们转换为'DateTime'？这本身就是一个严重的错误。 –

发布* full *例外，包括其调用堆栈。你可以用'Exception.ToString（）'得到它。还张贴实际引发错误的代码。你在这里发布的内容似乎并没有在任何地方使用日期 –

添加了异常和堆栈跟踪 – HarvP

你的例外规定发生了什么事在“没有fromdate”变量，它被设置为null。在那里使用断点，在“fromdate”内跟踪值，它不能小于1/1/1753 12:00:00 AM并且不能大于12/31/9999 11:59:59 PM。如果您尝试将DateTime类型的变量设置为null，则会发生此错误。声明该变量为可空，即DateTime?。这将解决问题。

有2列需要到期DateTime。 1是DateCreated，我们不允许为null，并且DateModified已经可以为null。 – HarvP

fromdate是一个DateTime类型？ –

没有从日期。我不确定你在哪里看到。有一个FormData类从具有DateCreated和DateModified的实体类继承。 – HarvP

这应该是注释，但它太长：

像@M阿迪尔·哈立德在他的回答表示，最常见条件造成这种异常试图把一个值在SQL Server datetime列即对于C＃有效但对于SQL Server无效。 可能发生的情况是关键，但很难从您提供的信息中分辨出来。

你的粘贴代码是哪一行出现异常？
堆栈跟踪（粘贴在下面）中的那些2行号码如何？

FrontOffice.HelperExtensions.FormProcessHelper.AddOnPremiumProcess（的Int32 ID）在C：\用户\ hprentiss \文件\ SI项目\ T3核心\开发\ FrontOffice \ HelperExtensions \ FormProcessHelper.cs：314

FrontOffice .Areas.NewBusiness.Controllers.ImportFormsController。ProcessFormAddOnPremium（Int32 id）in c：\ Users \ hprentiss \ Documents \ SI Project \ T3 Core \ Dev \ FrontOffice \ Areas \ NewBusiness \ Controllers \ ImportFormsController.cs：135

我想这些不是您自己的代码，但那就是你可能从中得到的线索。如果我们假设Datetime.Now是一个有效的值，那么将null的值更改为其他值，就像完整性检查一样？

这里没有Datetimes。 NHibernate发布了一个更新并决定一个空日期应该是最小值。 – HarvP

够公平的，但实际上这是“有DateTime的东西”。只是导致它在NHibernate内部发生并不会改变异常的性质。 – SlimsGhost
