【问题描述】：
我在打印验证时遇到了问题 视图中的输入字段。
我有一个希望用户填写表单的视图。在这个表格中我 需要在用户继续之前验证输入。在我的 dbModel 我对如何验证代码设置了不同的规则。在 我尝试使用的视图显示错误消息 Html.Validationssummary(true)
它在早期的项目中运行良好。但不是在这个...
这是 DbModel 类
public class Kjop
{
[Key]
public int ordreid { get; set; }
public int kundeid { get; set; }
public int produktid { get; set; }
public DateTime tid { get; set; }
[Required(ErrorMessage = "Fornavn må oppgis")]
[StringLength(50, ErrorMessage = "Maks 50 bokstaver")]
[DisplayName("Fornavn")]
public string fornavn { get; set; }
[Required(ErrorMessage = "Etternavn må oppgis")]
[StringLength(50, ErrorMessage = "Maks 50 bokstaver")]
[DisplayName("Etternavn")]
public string etternavn { get; set; }
[RegularExpression("^[a-z0-9_\\+-]+(\\.[a-z0-9_\\+-]+)*@[a-z0-9-]+(\\.[a-z0-9]+)*\\.([a-z]{2,4})$", ErrorMessage = "Ugylding formatering på epost")]
[Required(ErrorMessage = "feil i epost")]
[StringLength(50, ErrorMessage = "Maks 50 bokstaver")]
[DisplayName("Epost")]
public string epost { get; set; }
[Required(ErrorMessage = "Telefon må oppgis")]
[RegularExpression(@"[0-9]{8}", ErrorMessage = "8 tegn i telefonnr")]
[DisplayName("Telefon")]
public string telefon { get; set; }
[Required(ErrorMessage = "Adresse må oppgis")]
[StringLength(50, ErrorMessage = "Maks 50 bokstaver")]
[DisplayName("Adresse")]
public string adresse { get; set; }
[Required(ErrorMessage = "Postnr må oppgis")]
[RegularExpression(@"[0-9]{4}")]
[DisplayName("Postnummer")]
public string postnr { get; set; }
[Required(ErrorMessage = "Poststed må oppgis")]
[DisplayName("Poststed")]
public string poststed { get; set; }
public bool betalt { get; set; }
public int antall { get; set; }
}
变量名是挪威语，没关系。代码还在 任何语言都一样:)
我的控制器
public ActionResult Registrering()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Registrering(FormCollection innKunde)
{
try
{
using (var dbB = new databaseContext())
{
using (var dbP = new produktContext())
{
var produktId = from d in dbP.Produkter
where d.ProduktNavn.Equals(GlobalVariables.valgtProdukt)
select d;
int produktid = 0;
foreach (var b in produktId)
{
produktid = b.ProduktID;
}
var nyttKjop = new Kjop()
{
kundeid = 0,
produktid = produktid,
fornavn = innKunde["Fornavn"],
etternavn = innKunde["Etternavn"],
antall = Convert.ToInt32(GlobalVariables.produktAntall),
tid = DateTime.Now,
epost = innKunde["Epost"],
telefon = innKunde["Telefon"],
adresse = innKunde["Adresse"],
postnr = innKunde["Postnr"],
poststed = innKunde["Poststed"],
};
dbB.Kjoper.Add(nyttKjop);
dbB.SaveChanges();
Response.Write("Data lagt inn");
Session["Nykunde"] = nyttKjop;
//Adde sessions på variabler til kvitteringsiden
return RedirectToAction("Kredittkort");
}
}
}
catch (Exception feil)
{
Response.Write(feil);
return View();
}
}

当我尝试解析某些内容时出现以下异常...
System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
谁能帮我弄清楚我做错了什么？
