视图模型属性不能访问到ASP-路线-ID

Question

在此表中

<table border="1" cellpadding="10"> 
@foreach (var device in @Model.Devices) 
{ 
    <tr> 
     <td>@device.DeviceID</td> 
     <td>@device.DeviceName</td> 
     <td>@device.CALs</td> 
     <td align="right">@device.UnlockedFrom.ToShortDateString()</td> 
     <td align="right">@device.UnlockedTo.ToShortDateString()</td> 
     <td> 
      <a asp-action="DeleteDevice" 
       asp-controller="Manage" 
       asp-route-id="@device.DeviceId"> 
       Delete 
      </a> 
     </td> 
    </tr> 
} 

<td>@device.DeviceID</td>是好的，但asp-route-id="@device.DeviceId给人一种波浪device does not contain a definition for DeviceId

视图模型公开设备的集合

public IEnumerable<Device> Devices { get; set; } 

Device包括以下属性

public int DeviceID { get; set; } 
    public string UserId { get; set; } 
    public virtual ApplicationUser User { get; set; } 
    public int CALs { get; set; } 
    public string DeviceName { get; set; } 
    public DateTime UnlockedFrom { get; set; } 
    public DateTime UnlockedTo { get; set; } 

怎样使DeviceId可传递给控制器​​？

Answer 1

因为您的房产名称是DeviceID，而不是DeviceId。作为asp-route-*属性值传递的属性名称区分大小写。

更改您的代码

<a asp-action="DeleteDevice" asp-controller="Home" 
               asp-route-id="@device.DeviceID">Delete </a>
