重定向到URL的最佳方法（如果已更改）

Question

我有两个选项卡，在我的控制器中，我写了以下内容：

[HttpGet]
[Route("ViewSongAmendments")]
[AuthorizeTenancy(Roles = "super,administrator")]
public async Task<ActionResult> ViewSongAmendments(string songCode, int page = 1, int take = Constants.MVC.Pagination.DefaultItemsPerPage,
                                        string sortBy = "Membership", bool sortAsc = true)
{
    // AJAX?
    if (!Request.IsAjaxRequest())
    {
        return RedirectToAction("ViewSongAmendments", "SongsManagement");
    }

    return await GetWorkAndAmendmentDetails(songCode, page, take, sortBy, sortAsc);

}

[HttpGet]
[Route("UpdatedSongAmendments")]
[AuthorizeTenancy(Roles = "super,administrator")]
public async Task<ActionResult> UpdatedSongAmendments(string songCode, int page = 1, int take = Constants.MVC.Pagination.DefaultItemsPerPage,
                                        string sortBy = "Membership", bool sortAsc = true)
{
    // AJAX?
    if (!Request.IsAjaxRequest())
    {
        return RedirectToAction("UpdatedSongAmendments", "SongsManagement");
    }

    return await GetWorkAndAmendmentDetails(songCode, page, take, sortBy, sortAsc);
}

但是这就是我的Controller的样子，有没有更好的方法可以用来进行重定向。和往常一样，我使用：

// AJAX?
if (!Request.IsAjaxRequest())
{
    return View(model);
}
return PartialView("_ViewAmendmentsWriters", model);

控制器

我添加了控制器，因为如果它不是Ajax请求，我想返回模型。但是我不确定如何实现这一目标。

[HttpGet]
    [Route("ViewSongAmendments")]
    [AuthorizeTenancy(Roles = "super,administrator")]
    public async Task<ActionResult> ViewSongAmendments(string songCode, int page = 1, int take = Constants.MVC.Pagination.DefaultItemsPerPage,
                                            string sortBy = "Membership", bool sortAsc = true)
    {
        return await GetWorkAndAmendmentDetails(songCode, page, take, sortBy, sortAsc);
    }

    [HttpGet]
    [Route("UpdatedSongAmendments")]
    [AuthorizeTenancy(Roles = "super,administrator")]
