Question

此表正确填充@device.DeviceId但未将@device.DeviceId传递给控制器操作。

<table border="1" cellpadding="10">
    @foreach (var device in @Model.Devices)
    {
        <tr>
            <td>@device.DeviceId</td>
            <td>@device.DeviceName</td>
            <td>
                <a asp-action="DeleteDevice"
                   asp-controller="Device"
                   asp-route-id="@device.DeviceId" asp->
                    Delete
                </a>
            </td>
        </tr>
    }
</table>

控制器操作签名是

public async Task<IActionResult> DeleteDevice(int deviceId)

调用操作，但deviceId = 0。

如何确保@device.DeviceId正确传递给操作？

Answer 1

将控制器操作更改为：

public async Task<IActionResult> DeleteDevice(int id)

或更改a标记，以便asp-route-*属性与参数名称匹配，如下所示：

<a asp-action="DeleteDevice"
   asp-controller="Device"
   asp-route-deviceId="@device.DeviceId">
    Delete
</a>

asp-route-id不传递参数值
