如何在MVC C＃中将名称链接到ID

Question

I'm new to MVC in addition to C#, so... please work with me.

I'm developing a simple MVC project -

tables - prospects and contacts

My issue comes when I'm trying to link the prospect ID field in the contacts model to the prospect name from the prospect table.

Prospect Model -

public class Prospect
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string PostalCde { get; set; }
}

Activity Model -

public class Activity
{
    public int Id { get; set; }
    public string Type { get; set; }
    public DateTime Date { get; set; }

    public int ProspectId { get; set; }
    public int ProspectName{ get; set; }
}

Activity Controller

    public ActionResult Index()
    {
        return View(db.Activities.ToList());
    }

Activity Index View

@foreach (var item in Model) {
<tr>
    <td>
        @Html.ActionLink(item.Type, "Edit", "Activity", new { id=item.Id }, null)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.Date)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.ProspectId)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.ProspectName)
    </td>
    <td>

        @Html.ActionLink("Delete", "Delete", new { id=item.Id })
    </td>
</tr>
}

How can I link the prospectname to the prospectid in the activity model.

Eventually, I'd like to essentially join an activity to a prospect always, so the id and name are both automatically generated, but for now, I'm fine writing in the prospect id.

Any ideas would be greatly appreciated.

Answer 1

I am not sure I understand completely your requirement.

In Edit when you trying to change the Activity instead if textbo, use the dropdown which showing all the available Prospect Ids so one can select from only available Ids. So if you have available Prospect Id you can easily get its Name from table.

Answer 2

Do you just need help with the LINQ statement? If so, it would look something like this...

    Prospect p = dbContext.Prospects.Where(p => Name == "Smith").FirstOrDefault();

(...replacing "Smith" with whatever the name is, obviously).
