如何在SelectList编辑ASP.NET MVC中组合两个字段

public class CombinedField
{
    public string Field1 { get; set; }
    public string Field2 { get; set; }
}

public ActionResult Index()
{
    // 获取数据
    var data = GetCombinedFieldData();

    // 转换为CombinedField对象的集合
    var combinedFields = data.Select(d => new CombinedField
    {
        Field1 = d.Field1,
        Field2 = d.Field2
    });

    // 创建SelectList
    var selectList = new SelectList(combinedFields, "Field1", "Field2");

    // 将SelectList传递给视图
    ViewBag.SelectList = selectList;

    return View();
}

@model YourModel
@{
    ViewBag.Title = "Index";
}

@Html.DropDownListFor(m => m.SelectedCombinedField, (SelectList)ViewBag.SelectList, "请选择")
