How to connect selected DropDownList value to @Url.Action?

Question

ASP.NET

Added control to the view

@{
                    var listItems = new List<ListItem>
                    {
                            new ListItem  { Text = "item1", Value="item1" },
                            new ListItem  { Text = "item2", Value="item2" },
                            new ListItem  { Text = "item3", Value="item3" }
                    };
                }
@Html.DropDownList("ddlist", new SelectList(listItems, "Value", "Text"))

there is already something like this

<a target="_blank" href="@Url.Action("Download", new { t = ViewData["Token"] })" class="rn-button rn-button-sm rn-button_white">
                    <i class="rn-icon rn-icon-download"></i>
                    <span class="rn-button__text">Скачать</span>
                </a>

Those. a button that downloads a certain document.
How can I augment this Action so that it passes not only the Token, but also the value of the DropDownList?

HTML forms , or using js to change the GET request parameters.
