Question

我正在尝试将基于视图的应用程序更改为API。解决这个项目here。

我无法返回OkObjectResult。为什么会这样，为什么ASP移到IActionResult vs ActionResult？

[HttpGet]
public IActionResult Index()
{
    List<ApplicationRoleListViewModel> model = new List<ApplicationRoleListViewModel>();
    model = roleManager.Roles.Select(r => new ApplicationRoleListViewModel
    {
        RoleName = r.Name,
        Id = r.Id,
        Description = r.Description,
        NumberOfUsers = r.Users.Count
    }).ToList();
    return OkObjectResult(model);
}

OkObjectResult是一个课程而非方法，您需要对其进行新的修改：return new OkObjectResult(model)或使用helper method that exists on the controller：

return Ok(model);

不可调用的OkObjectResult不能像方法一样使用
