的参数化查询 '（@ 0 nvarchar的（3），@ 1个为nvarchar（12），@ 2为nvarchar（8），@ 3为nvarchar（4），@ 4' 预期参数'@ 8'，没有提供。 –

检查你是否确实有一个名为“Truck_Vin”的表单字段 –

你@ 8列出两次，而你错过了@ 4。

是的，我在我的代码中解决了这个问题，但仍然给出了同样的错误，我认为@ 4是说应该是@ 8，所以我改变了Truck_Vin = @ 4到8，只是为了检查，但忘记把它放回到4之前张贴在这里。虽然它仍然是相同的错误... –

好简单的数学：从@ 0到@ 19有20个变量吗？但是从Request.Form []'获得19个值，我想你应该在db.Execute（）方法中传递一个值。 – mihkov

是在该块中有19个Request.Form [“”]变量，但最顶端是1，它是var ID = Request [“id”]变量，因为这是一个更新查询，它将该变量从URL本身truck_edit.cshtml？id = 2场景。这是列表中@ 19，并在最后的db.Execute（updateQueryString ,,,,,,,,,,,,,,,, ID）设置... –
