Question

我有一个DataTable，如下所示：

TOTAL_CODE COD_NAME AP0001学校 AP0002医院 AP0003机场 AP0004之家

我是ASP.NET MVC3的新手，我无法弄清楚如何将DataTable绑定到我的DropDownListFor控件。

PS：我的模型如下：

@model Kery.Models.Profile
@{
    ViewBag.Title = "DetailAdd";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<P>Please select your sex type: @Html.DropDownListFor(..............)</p>

型号：

public class Profile
{
    public IEnumerable<SelectListItem> SexList { get; set; }
}

控制器：

[HttpGet]
public ActionResult DetailAdd()
{
    System.Data.DataTable _dtJikchaekList = _bp.DtReturnS(false
     , "CHP_AJAX_CODEHELPER"
     , "JJ"
     , ""
     , "0"
     );
    return View();
}

这是一种方法。

Edit:

 //you can take this as a Sex Model
            public class Sex {
                public string gender { get; set; }
                public string shortname { get; set; }
            }
            public List<SelectListItem> SexList() {
                //if you have your sex model in the database , you can get it here

                //I have a static content below, just to show you how you can manuplate the sex model,
                List<Sex> s = new List<Sex>() { new Sex() { gender = "Male", shortname = "M" }, new Sex() { gender = "Female", shortname = "F" } };

                List<SelectListItem> items = new List<SelectListItem>();
                //go through the sex model and populate you selectlist items
                foreach (Sex sex in s) {
                    SelectListItem item = new SelectListItem();
                    item.Text =sex.gender;
                    item.Value =sex.shortname;
                    items.Add(item);
                }
                return items;
            }

在您的控制器上

[HttpGet]
public ActionResult DetailAdd()
{
    Profile profile = new Profile();
    //set the sex types
    profile.SexList=SexList();

    return View(profile);
}

你的观点

@model Kery.Models.Profile
@{
    ViewBag.Title = "DetailAdd";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<P>Please select your sex type: @Html.DropDownListFor("name",Model.SexList)</p>

                    objcountrty.Add(new Country { ID = d1, LName = d2 });
                }
                return objcountrty;
            }

我发现所有其他方法都非常令人困惑，所以我在我看来这样做，似乎工作得很好。零是表的列索引。我正在使用vb.net

<select>
    @Code
        For Each row In Model.dataTable.Rows
            @<option>@row(0)</option>
        Next
    End Code
</select>

如何在asp.net MVC3中将DataTable绑定到@ Html.DropDownListFor
