c# - Object Reference not set to an object (calling Razor model from View)

Using C# MVC4

My View:

@using Universe.Models
@model UserModel
@section css {
}
@using (Html.BeginForm("AddUser","Home", FormMethod.Post))

{


            







My Model:

public class UserModel

{
    public int Id { get; set; }
    public string Alias { get; set; }
    public string Email { get; set; }
    public string Password { get; set; }
    public bool IsExternal { get; set; }


    public UserModel()
    {


    }

    public UserModel(User user)
    {
        if (user == null) return;
        Alias = user.Alias;
    }
}



But, I keep getting the error: 



When I try to debug it, it doesn't even go into the Html.TextBox method or into my model.
 
Answer
 

Without seeing your controller action, my guess would be that your model is null.

In your controller, make sure you are passing an instance of the model to your view. For example:


return View(new UserModel());


Instead of:

return View();
