<form enctype="multipart/form-data" method="post" asp-controller="Exposure" asp-action="Upload">
    <div class="row">
        <div class="form-group">
            <select class="form-control-sm" >
                <option selected>Choose a Database</option>
                <option value="SICS">SICS</option>
                <option value="TranslationTable">Translation Table</option>
            </select>

    </div>
    <div class="row">
        <div class="col-6 mb-3">
            <div class="custom-file">
                <input type="file" class="custom-file-input" name="DBTemplate" />

    in your view:

    <select class="form-control-sm" name="somename >

    in your action:

     public IActionResult Upload(IFormFile DBTemplate,string somename)
        {
            .......
            return View();
        }

    Add name attribute to bind selectedItem,then you can pass selected item from dropdown list to the controller

    <select class="form-control-sm" name="selectedItem" >
                    <option selected>Choose a Database</option>
                    <option value="SICS">SICS</option>
                    <option value="TranslationTable">Translation Table</option>
                </select>

    result:
