以下是我的观点:
@foreach (var item in Model)
{
if(i == 0)
{
@:<div class="row">
}
<div class="col-md-3 col-xs-12" style="margin-top:20px;">
@Html.ActionLink(item.Name, "ClientDetail", "Client", null, new { @class = "btn btn-primary btn-block", id = @item.id})
</div>
i++;
if(i%4 == 0)
{
@:</div>
i = 0;
}
}
这是控制器:
public ActionResult ClientDetail(int id)
{
ClientModel model = cserv.Get(id, User.Identity.GetUserId());
ClientViewModel viewModel = new ClientViewModel(model);
return View(viewModel);
}
每次点击我的某个链接时,都会出现此错误:
The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult ClientDetail(Int32)' in 'TechUCRM.Controllers.ClientController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
为什么我的id参数没有传递给控制器?
谢谢!

您希望将ID放在 routeValues 参数中。
@Html.ActionLink(item.Name, "ClientDetail", "Client",
new { id = item.id},
new { @class = "btn btn-primary btn-block"})
与
相同@Html.ActionLink(item.Name, "ClientDetail", "Client",
routeValues: new { id = item.id },
htmlAttributes: new { @class = "btn btn-primary btn-block" })

更改此行:
@Html.ActionLink(item.Name, "ClientDetail", "Client", null, new { @class = "btn btn-primary btn-block", id = @item.id})
为:
@Html.ActionLink(item.Name, "ClientDetail", "Client", new{ id= item.Id }, new { @class = "btn btn-primary btn-block"})
你用过的那个设置了HTML的id属性。它不是路由的ID。
