            {
                var comment = charity.Comment.ToLower().Replace("hot", "###").Replace("cold", "###").Replace("Slow", "###").Replace("enjoy", "###").Replace("BAD", "###");
                charity.Comment = comment;  //Replaces textx from model variable - comment

                charity.TaxBonus = 0.20 * charity.Amount;

                charity.DisplayName = "Annonymus"; //If user doesnt enter name then Annonymus


            }


            db.Donations.Add(charity);
            db.SaveChanges();

                @Html.ValidationMessageFor(model => model.TaxBonus, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">

AdditionalInfo ActionResult

AdditionalInfo ActionResult

[HttpGet]
    public ActionResult Additionalinfo(int id)
    {

        return View("Additionalinfo", new { id });
    }

AdditionalInfo View

AdditionalInfo视图

@{
    ViewBag.Title = "Additionalinfo";
}

<h2>Additionalinfo</h2>

Model

模型

  public class Charity
{
    public int ID { get; set; }
    [RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]
    public string DisplayName { get; set; }

    [DataType(DataType.Currency)]
    [Range(2, Int32.MaxValue, ErrorMessage = "Atleast £2.00 or a whole number please")]
    public int Amount { get; set; }
    [DataType(DataType.Currency)]
    public Double TaxBonus { get; set; }
    public String Comment { get; set; }
}

public class CharityDBContext : DbContext //controls information in database 
{
    public DbSet<Charity> Donations { get; set; } //creates a donation database
}

Hi I am trying to get the information Inputted from the "Create" to be displayed in the "Confirmation", I can just display the database but what I want is the specific information to be carried onto the next page, rather than a whole database. I am new to MVC so trying to get the hang of this.

你好,我正在尝试从“Create”中输入的信息显示在“confirm”中,我可以只显示数据库,但是我想要的是将特定的信息传递到下一个页面,而不是整个数据库。我是MVC的新手,所以我试着弄懂它。

I have created it on a new ActionResult which works but I can't get the passing data to work.

我在一个新的ActionResult上创建了它,它可以工作,但是我不能让传递的数据工作。

You may use session for that:

您可以使用会话来实现:

var products=Db.GetProducts();

//Store the products to a session
Session["products"]=products;

//To get what you have stored to a session
var products=Session["products"] as List<Product>;
