I am making a page. I am trying to make a DropDownList on this page. There should be two items in this DropDownList. I am trying to determine these two items through the Controller.

But I am getting an error like this:

My codes:

Index.cshtml:

@model IncomeAndExpensiveWeb.Models.IncomeExpensiveTable
@{
    ViewData["Title"] = "Money";
}

<div >Add</div>
<form  action="IncomeExpensiveTables/AddRecord" method="post">
    <div >
        <div >
            <div >
                <label for="Name" >Name:</label>
                @Html.TextBoxFor(m => m.Name, new { @class = "form-control" })
            </div>
        </div>
        <div >
            <div >
                <label for="Surname" >Surname:</label>
                @Html.TextBoxFor(m => m.Surname, new { @class = "form-control" })
            </div>
        </div>
        <div >
            <label>
                <select >
                    @foreach (var item in (IEnumerable<IncomeExpensiveTable>)ViewBag.MoneyStatusList)
                    {
                        <option value="@item.Id">@item.MoneyStatus</option>
                    }
                </select>
            </label>
        </div>  
        <div >
            <label>Image:</label>
            <input type="File" name="UploadedImage"/>
        </div>
        <br/>
        <div>
            <button >Add</button>
        </div>
    </div>
</form>

Controller:

[HttpGet]
public ActionResult Index()
{
    List<string> MoneyStatusList = new List<string>();
    MoneyStatusList.Add("Income");
    MoneyStatusList.Add("Expensive");
    ViewBag.MoneyStatusList = MoneyStatusList;
    return View("Index");
}

Why could this be? How can I solve it? Thanks for help.

select >
                    @foreach (var item in (IEnumerable<IncomeExpensiveTable>)ViewBag.MoneyStatusList)
                    {
                        <option value="@item.Id">@item.MoneyStatus</option>
                    }

"IncomeExpensiveTable" is string on code behind. Thats why you can't cast.

CodePudding user response：

You have to cast it your ViewBag model type which is List() and only use just item there is no any item.Id or item.MoneyStatus.

Like this:

 <select >
                @foreach (var item in (List<string>)ViewBag.MoneyStatusList)
                {
                    <option value="@item">@item</option>
                }
  </select>
