MVC Printing out each Enum value through @foreach

Question

Enum:

    public enum Enumenter
    {
        Products = 10,
        Users = 20,
        Actions = 30
    }

my view:

@model IEnumerable<ServerDB.Tables.EntityType>

@{

    ViewBag.Title = "Infrastruktur";
}


<table class="table">
<tr>
    <th>

        <h2>Infrastruktur</h2>
    </th>

    <th></th>
</tr>

@foreach (var val in Enum.GetNames(typeof(ServerDB.Tables.Enum)))
{


    <tr>
        <td>
            @Html.DisplayName((String.Format("{0}{1}", val, "2")))

        </td>
        <td></td>
        <td>
            <p>
            </p>
        </td>
        <td></td>
    </tr>
}
@foreach (var Ost in Enum.(typeof(ServerDB.Tables.Enum)))
{
    @Html.DisplayName((String.Format("{0}", Ost)))
}

</table>

How do i Print out The values next to the products? im going to use the numbers from the enum to make a query search, so i can search for any product, any users or actions for that matter. im no expert in this, so please be gentle.

you have to cast it to ``int`` like : ``Convert.ToInt32(val)`` — Ehsan Sajjad, Sep 10 '15 at 07:15
Can you explain or link me to what "casting" is? And many thanks for the help. — user3439890, Sep 10 '15 at 07:17
you need value againt enum text so you have to cast it to `int` as the values are ``int`` — Ehsan Sajjad, Sep 10 '15 at 07:18

https://learn.microsoft.com/en-us/dotnet/api/system.enum.parse?view=net-7.0#system-enum-parse(system-type-system-string) has the example showing how to use Enum.GetNames() in tandem with Enum.Parse() (similar example in Enum.GetValues() section) — gawkface, Jan 23 '23 at 21:10

Enum.GetValues returns values for the enum as objects, so you need to cast them to int value (using int instead of var will do that for you). After that you can use Enum.GetName to get the name for specific value:

@foreach (int val in Enum.Values(typeof(ServerDB.Tables.Enum)))
{
   var name = Enum.GetName(typeof(ServerDB.Tables.Enum), val);

    <tr>
        <td>
            @Html.DisplayName((String.Format("{0}{1}", name, "2")))

        </td>
        <td>
            @val
        </td>
        <td>
            <p>

            </p>
        </td>
        <td>

        </td>
    </tr>
}

There is another approach which doesn't use the Enum.GetName method. You simply cast the value you get from Enum.Values to string to get the name and to int to get the value

@foreach (var name in Enum.Values(typeof(ServerDB.Tables.Enum)))
{
    var val = (int)name;
    <tr>
        <td>
            @Html.DisplayName((String.Format("{0}{1}", name, "2")))

        </td>
        <td>
            @val
        </td>
        <td>
            <p>

            </p>
        </td>
        <td>

        </td>
    </tr>
}

@user3439890 I've updated the answer, you should change the `var` to `int` keyword so that it gets the real value – Vsevolod Goloviznin Sep 10 '15 at 07:23
@user3439890 Awesome, you can mark this as an answer :) – Vsevolod Goloviznin Sep 10 '15 at 07:34

I think that you can do `val.ToString()` instead of `Enum.GetName(typeof(ServerDB.Tables.Enum), val);` – Alex Art. Sep 10 '15 at 07:34
