Question

我想从我的视图中传递id值。我正在使用Html.ActionLink属性。我表现得像这样

  @foreach (var item in Model)
{

    <div class="grid_1_of_4 images_1_of_4">

        <a href="preview.html"><img src="/@item.p_imageUrl" alt="" /></a>
        <h2>@item.p_name </h2>
        <div class="price-details">
            <div class="price-number">
                <p><span class="rupees">@item.p_price</span></p>
            </div>
            @Html.ActionLink("Add to Cart", "Mobiles", new { id = item.ProductId }, new { @class = "add" })
            <div class="clear"></div>
        </div>

    </div>
}

但是这不会发布它而是让动作在控制器中调用。如何修复

您可以使用可选参数功能对这两个操作使用一个操作，无需执行其他操作：

public ActionResult Mobiles(int id=0) 
{ 
// id will be initialized 0 when no id passed to action
if(id > 0)
{

// if id is coming do something here

var q = from n in db.Mobiles 
        where n.ProductId == id
        select n;  

 return View(q);

}

else
{
 var q = from n in db.Mobiles 
         select n;             // id is not passed

 return View(q);
}


}

从正在接收IEnumerable List的视图中传递id值
