问题描述：在ASP.NET中，有些用户反馈ASPNetUserRoles中的Edit和DeleteConfirmed方法工作不正常，导致删除和编辑用户角色时出现错误。原因是在这些方法中缺少对数据库中删除和编辑操作的确认，导致操作失败。

在Edit和DeleteConfirmed方法中添加确认操作，以确保正确的操作。例如：

//Edit方法 [HttpPost] [ValidateAntiForgeryToken] public async Task Edit([Bind(Include = "UserId,RoleName")] EditUserRoleViewModel editUserRoleViewModel) { if (ModelState.IsValid) { var result = await UserManager.RemoveFromRolesAsync(editUserRoleViewModel.UserId, await UserManager.GetRolesAsync(editUserRoleViewModel.UserId)); if (result.Succeeded) {

        result = await UserManager.AddToRoleAsync(editUserRoleViewModel.UserId, editUserRoleViewModel.RoleName);
        if (result.Succeeded)
        {
            return RedirectToAction("Index");
        }
    }
    ModelState.AddModelError("", result.Errors.First());
}

ViewBag.UserId = new SelectList(await UserManager.Users.ToListAsync(), "Id", "UserName", editUserRoleViewModel.UserId);
ViewBag.RoleName = new SelectList(await RoleManager.Roles.ToListAsync(), "Name", "Name", editUserRoleViewModel.RoleName);
return View(editUserRoleViewModel);

}

//DeleteConfirmed方法 [HttpPost, ActionName("Delete")] [ValidateAntiForgeryToken] public async Task DeleteConfirmed(string id) { var user = await UserManager.FindByIdAsync(id); var result = await UserManager.DeleteAsync(user); if (result.Succeeded) { return RedirectToAction("Index"); } ModelState.AddModelError("", result.Errors.First()); return View(); }

通过添加确认操作，可以解决ASPNetUserRoles中的Edit和DeleteConfirmed方法工作不正常的问题。
