ModelState.IsValid is always returning false
提问by Mizbella
[HttpPost]
public ActionResult Create(Users user)
{
if (ModelState.IsValid)
{
db.Users.Add(user);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(user);
}
ModelState.IsValidis always false.
so it just return view and new record is not getting added..
ModelState.IsValid总是假的。
所以它只是返回视图并且没有添加新记录..

ModelState.IsValidwill be false if the validation for the Model failed.
ModelState.IsValid如果模型验证失败，则为 false。
- You have DataAnnotationwhich failed the incoming model.
- You added custom validations.
- Make sure there are no null entries in the model for non null properties
- 您的DataAnnotation使传入模型失败。
- 您添加了自定义验证。
- 确保模型中没有非空属性的空条目
Check the ModelState.Errorsfor what is the reason causing this. You can use this:
检查ModelState.Errors导致这种情况的原因是什么。你可以使用这个：
var errors = ModelState.Values.SelectMany(v => v.Errors);
