Question

我想在我的视图中从复选框中返回一个Personnes列表，并在我的控制器中获取它，但selectedObjects count始终为0 ...

这是我的复选框视图：

--SET VARIABLE FOR A REGISTRATION MARK
DECLARE @Reg nvarchar(10);
SET @Reg = 'PH-BGO';

--SET VARIABLE FOR MANUFACTURER OF REGISTRATION MARK
DECLARE @Manufacturer nvarchar(100);
SET @Manufacturer = (SELECT FleetInfoKLM.Manufacturer FROM FleetInfoKLM WHERE FleetInfoKLM.Reg = @Reg);

--SET VARIABLE FOR FAMILY OF REGISTRATION MARK
DECLARE @Family nvarchar(100);
SET @Family = (SELECT FleetInfoKLM.Family FROM FleetInfoKLM WHERE FleetInfoKLM.Reg = @Reg);

--SET VARIABLE FOR SERIES OF REGISTRATION MARK
DECLARE @Series nvarchar(100);
SET @Series = (SELECT FleetInfoKLM.Series FROM FleetInfoKLM WHERE FleetInfoKLM.Reg = @Reg);

--SHOW LOCAL VARIABLES VALUES
SELECT @Manufacturer;
SELECT @Family;
SELECT @Series;

--SELECT MAINTENANCE DOCUMENTS BASED ON VARIABLES FOR MANUFACTURER, FAMILY AND SERIES
SELECT MaintenanceDocumentation.name FROM MaintenanceDocumentation
WHERE MaintenanceDocumentation.path_locator IS NOT NULL
    AND CONTAINS(file_stream, @Manufacturer)
    AND CONTAINS(file_stream, @Family)
    AND CONTAINS(file_stream, @Series);

我的控制员：

@using (Html.BeginForm("Presence", "Evenement"))
{
    foreach (var p in Model.Personnes)
    {
        <input type="checkbox" name="selectedObjects" value="@p" />
    }
    @Html.AntiForgeryToken()
    <input type="submit" value="Valider Presence" class="btn btn-primary" />
}

您无法将复选框绑定到复杂对象。复选框仅回发单个值。相反，您需要绑定到Personne的属性，例如，如果它具有属性int ID，那么

foreach (var p in Model.Personnes)
{
    <input type="checkbox" name="selectedObjects" value="@p.ID" />
}

然后将POST方法签名更改为

public ActionResult Presence(int[] selectedObjects)

从复选框返回对象列表
