I have method called 'Upload' that will receive two parameters (IformFile and a string value) how can i pass the selected item from my dropdown list to my controller which is the string parameter in my method.

<form enctype="multipart/form-data" method="post" asp-controller="Exposure" asp-action="Upload">
    <div >
        <div >
            <select  >
                <option selected>Choose a Database</option>
                <option value="SICS">SICS</option>
                <option value="TranslationTable">Translation Table</option>
            </select>
        </div>
    </div>
    <div >
        <div >
            <div >
                <input type="file"  name="DBTemplate" />
                <label  for="customFile">Choose file</label>
                <i>Only Excel file .xls, .xlsx</i>
            </div>
        </div>
    </div>

        <div >
            <div >
                <button type="submit" id="submit" name="Submit" >Upload</button>
                <button asp-controller="Exposure" asp-action="Index" type="button"  data-dismiss="modal">Back to list</button>

            return View();
        }

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

<select  name="selectedItem" >
                    <option selected>Choose a Database</option>
                    <option value="SICS">SICS</option>
                    <option value="TranslationTable">Translation Table</option>
                </select>
