Asp.net mvc 5 如何在CRUD功能中映射复合键

我需要基于两个键（comp和part）进行映射

---

如果有人有想法，请回复。

find方法通过主键查找实体。如果您有复合主键，则按照在模型中定义的顺序传递键值：

@Html.ActionLink("Edit", "Edit", new { comp = item.comp, part = item.part }) |   
@Html.ActionLink("Details", "Details", new { comp = item.comp, part = item.part }) |
@Html.ActionLink("Delete", "Delete", new { comp = item.comp, part = item.part })

在控制器中，接收两个值：

public ActionResult Edit(int? comp, int? part)
{
    DataView record = db.RecordDataView.Find(comp, part);
    if (record == null)
    {
        return HttpNotFound();
    }
    return View(record);
}

在应用上述建议时，我得到了一个错误：

The parameters dictionary contains a null entry for parameter 'isdel' of non-nullable type 'System.Boolean' for method 'System.Web.Mvc.ActionResult Edit(System.Nullable`1[System.Int32], Boolean)' in Controller'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

但根据 我尝试将细节更改为动作签名

public ActionResult Details(int eid,bool isdeleted) //same parameter name as in my Entity Model.

带有复合键的CRUD功能现在正常执行

谢谢@Jelle Oosterbosch

非常感谢！4年后仍在帮助人们
