2下拉列表mvc4創建自定義的驗證

Question

我有這兩個下拉列表，都應該是年齡和我想要讓這個你不能做比最大年齡

<div class="col-lg-3 col-md-3 col-sm-3 editor-group "> 
    @Html.Label("Mininum Age") 
    @Html.DropDownListFor(model => model.Preference.MinAgeId, new SelectList(Model.MinAges, "AgeId", "CurAge", Model.Preference.MinAgeId),"-Any-", new { @class = " form-control" }) 
    @Html.ValidationMessageFor(model => model.MinAges) 
</div> 
<div class="col-lg-3 col-md-3 col-sm-3 editor-group "> 
    @Html.Label("Maximum Age") 
    @Html.DropDownListFor(model => model.Preference.MaxAgeId, new SelectList(Model.MaxAges, "AgeId", "CurAge", Model.Preference.MaxAgeId),"-Any-", new { @class = " form-control" }) 
    @Html.ValidationMessageFor(model => model.MaxAges) 
</div> 

我不知道，較高的最低年齡如果我創建下拉列表的方式可以使用此nuget包MVC Foolproof Validation來標記它在其他所有下拉列表之間是否無效

Answer 1

。你將能夠做到這一點。如果你不想使用外部庫。您可以在您的模型上實現IValidatableObject並在那裏對驗證進行編碼。
