我目前在从实体框架更新 NopCommerce 数据库时遇到了一个非常烦人的问题。

背景：

我正在编写一个小工具来将一种过时的电子商务应用程序迁移到 nopCommerce。

错误：

The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.
The statement has been terminated.

我做了什么来尝试解决它

过去，当我有一个未初始化的 DateTime 属性（0001 年）时，就会出现这种错误。但在这种情况下，这不是问题所在。我查看并确保正在设置所有 DateTime 属性。由于那不起作用，我也尝试制作 db 列datetime2(7)，但没有运气。最后我将它设置为NULLABLE但它仍然给了我同样的错误。因此，显然这里发生了其他事情，EF 抛出了一些无用的错误。我想知道表上是否可能有一个插入触发器（或任何触发器）试图在产品变体表或另一个表中创建一个条目，然后日期时间错误来自该表，但这不是案子。

编码：

foreach (var piloProduct in piloProducts)
{
    var product = new Models.Nop.Product
    {
        Name = piloProduct.Name,
        ShortDescription = piloProduct.ShortDescription,
        FullDescription = piloProduct.FullDescription,
        ProductTemplateId = 1,
        ShowOnHomePage = false,
        MetaKeywords = piloProduct.MetaKeywords,
        MetaDescription = piloProduct.MetaDescription,
        MetaTitle = piloProduct.MetaTitle,
        SeName = piloProduct.SeName,
        AllowCustomerReviews = false,
        ApprovedRatingSum = 0,
        NotApprovedRatingSum = 0,
        ApprovedTotalReviews = 0,
        NotApprovedTotalReviews = 0,
        Published = true,
        Deleted = false,
        CreatedOnUtc = DateTime.UtcNow,
        UpdatedOnUtc = DateTime.UtcNow
    };
    nopDb.Products.AddObject(product);
}
nopDb.SaveChanges();

我对这个完全不知所措，因为上面的代码非常简单明了。非常感谢任何帮助。

我刚刚尝试使用 Linq-To-SQL 类而不是实体框架 EDMX，但遇到了完全相同的问题。奇怪的是，我直接从 SQL Management Studio 在表上运行了一个“INSERT INTO”语句，但它起作用了.. 去看看......有什么方法可以准确地查看 EF 或生成的“INSERT”语句Linq 到 SQL？

这是 Mark Oreta 要求的 EDMX 生成模型：

是的，我知道发生了什么......基本上，我在事务中运行这一切，并且在产品之前导出其他实体（类别）。问题是我在添加所有类别后没有打电话SaveChanges()......所以出现的错误是关于类别表而不是产品表，但我只有SaveChanges()在我添加后才收到消息产品也是如此..非常令人困惑..我希望将来他们会通过说明错误来自哪个表来更清楚地说明..这将节省大量时间。

这是我的情况，你看不到为什么我没有立即发现问题所在：

using (var transactionScope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromMinutes(30)))
            using (var piloDB = new PiloEntities())
            using (var eSalesDB = new ESalesEntities())
            {
                ExportCategories(piloDB, eSalesDB); //SaveChanges() not called in here
                ExportProducts(piloDB, eSalesDB); //SaveChanges() is called in here
                //export other...
