我有一个使用模态窗体的web应用程序来确认我的用户（或管理员）可能允许执行的一些操作。模式表单设置取自微软的IdentitySampleApplication项目，并且在我的项目中以大体相同的方式结合了这一点。我正在使用通用模态窗体。我试图让用户在应用程序上拥有多个用户角色（虽然他们的示例假设用户只有一个角色）。MVC.NET Core Bootstrap-Modal forms with multi-parameters do not reach Post控制器
我现在正在制定删除此类型多角色方案的角色保养。我应该指出，只涉及一个id的代码的所有实例都可以正常工作，这是一个具有2个id的实例，它无法通过控制器中需要的任何一个id。
删除用户角色需要用户和角色的关键。 我的控制器有一些类似于下面的代码来接受id并呈现一种模式形式，其工作得非常好。
[HttpGet]
public IActionResult DeleteUserRole(string userid, string roleid){...}
的HttpPost部分看起来像这样
[HttpPost]
public IActionResult DeleteUserRole(string userid, string roleid, IFormCollection form){...}
然而，这第二个动作永远不会被传递到模式窗体的IDS get方法。
在只有一个路由ID的所有方法中，我没有问题。只有这一种方法让我烦恼。我从这个链接调用它。请注意两个ASP-路线变量，我怀疑这是我的问题的心脏，但get调用是罚款与此，它是没有价值的帖子：
<a id="deleteRoleModal" asp-action="DeleteUserRole"
asp-route-userid="@item.userId" asp-route-roleid="@item.roleId"
data-toggle="modal" data-target="#modal-action-role"
class="btn btn-sm btn-danger">
，其中在该基地形成我有一个模式的形式实现它使用看起来像这样：
@await Html.Partial("_Modal", new BootstrapModel { ID = "modal-action-role", AreaLabeledId = "modal-action-role-label", Size = ModalSize.Medium })
我的情态的形式看起来很像在IdentitySampleProject使用的样品，并在这里显示，它没有以任何有意义的方式改变尚未正常工作与单参数回调：
@model string
@using MyModels
<form asp-action="DeleteUserRole" role="form">
@Html.AntiForgeryToken()
@await Html.Partial("_ModalHeader", new ModalHeader { Heading = "Delete User Role" })
<div class="modal-body form-horizontal">
Are you sure you want to delete user role @Model?
</div>
@await Html.Partial("_ModalFooter", new ModalFooter { SubmitButtonText = "Delete" })
</form>
我正在寻找解决问题的方向。我希望确实双线路ID是我的问题，但我似乎无法找到其他人在样本中做这样的事情。
