如何基于角色显示或隐藏控件 - ASP.NET MVC 4 Razor

Install-Package Microsoft.AspNet.Identity.EntityFramework

var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
    // 添加用户到指定角色
    await UserManager.AddToRoleAsync(user.Id, "YourRoleName");
}

@using Microsoft.AspNet.Identity
@using YourProjectName.Models

@if (Request.IsAuthenticated)
{
    var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
    var currentUser = userManager.FindById(User.Identity.GetUserId());

    if (userManager.IsInRole(currentUser.Id, "YourRoleName"))
    {
        // 用户属于指定角色，可以显示控件
        @RenderSection("RoleBasedAccessControl", required: false)
    }
}

@section RoleBasedAccessControl {
    <!-- 在此处添加需要基于角色显示或隐藏的控件 -->
}
