将Enum值用作下拉列表ASPCore中的值

Question

Im trying to use a value from an enum I've declared in my code previously

Here is the enum :

public enum CompanyStatus
{
    WaitingForApproval = 1,
    Approved = 2,
    Disapproved = 3
}

Here is the select list where I am trying to use that Id that has been already declared

<select id="CompanyStatusFilter" validateme="true" class="form-control fullWidth" placeholder="Status" data-validation="length alphanumeric" data-validation-length="min1">
                            <option value=""></option>
                            <option value="(int)Core.Engine.CompanyStatus.Approved">Approved</option>
                            <option value="@Html.GetEnumSelectList<CompanyStatus>">Waiting for approval</option>                                
                        </select>

I don't want to explicitly type in the id as the value. Thanks in advance

Answer 1

IMHO it would be better if you used the helper for Enums for example:

@Html.DropDownListFor(m => m, Html.GetEnumSelectList(Model.GetType()))

and on the Enum values you can use the [Display(Name = "Test 1")] attribute to control what gets shown.

Answer 2

You can use GetEnumSelectList to render a select for the enum values.

<select name="CompanyStatus" asp-items="Html.GetEnumSelectList(typeof (CompanyStatus))">
</select>

我能够通过将其转换为Int32来获取枚举的ID

<option value="@Convert.ToInt32(Core.Engine.CompanyStatus.WaitingForApproval)">Waiting for approval</option>
