如何使用aspnet core c#从双重列表框中检索选定的值

<select id="availableItems" multiple>
  <option value="1">Item 1</option>
  <option value="2">Item 2</option>
  <option value="3">Item 3</option>
  <!-- 其他可选项 -->
</select>

<button id="moveToSelected">Move to Selected</button>
<button id="moveToAvailable">Move to Available</button>

<select id="selectedItems" multiple>
  <!-- 选定的项目将在这里显示 -->
</select>

document.getElementById("moveToSelected").addEventListener("click", function() {
  var availableItems = document.getElementById("availableItems");
  var selectedItems = document.getElementById("selectedItems");

  for (var i = 0; i < availableItems.options.length; i++) {
    var option = availableItems.options[i];
    if (option.selected) {
      selectedItems.appendChild(option);
      i--;
    }
  }
});

document.getElementById("moveToAvailable").addEventListener("click", function() {
  var availableItems = document.getElementById("availableItems");
  var selectedItems = document.getElementById("selectedItems");

  for (var i = 0; i < selectedItems.options.length; i++) {
    var option = selectedItems.options[i];
    if (option.selected) {
      availableItems.appendChild(option);
      i--;
    }
  }
});

[HttpPost]
public IActionResult GetSelectedValues(List<string> selectedValues)
{
  // 处理选定值的逻辑
  // 返回结果或执行其他操作
}
