我正在使用ASP.NET MVC 3,我有一个视图模型如下:
public class RegistrationViewModel
{
public IList<LicenseViewModel> Licenses { get; set; }
}
public class LicenseViewModel
{
public string LicensedState { get; set; }
public string LicenseType { get; set; }
}
用户可以在多个状态下获得许可,并且LicensedState和LicenseType值都应显示为网格页脚上的下拉列表。如何使用RegistrationViewModel创建视图?

public class RegistrationViewModel
{
public IList<LicenseViewModel> Licenses { get; set; }
}
public class LicenseViewModel
{
public string LicensedState { get; set; }
public string LicenseType { get; set; }
public IEnumerable<LicenseState> LicenseStates { get; set; }
public IEnumerable<LicenseType> LicenseTypes { get; set; }
}
视图
@model RegistrationViewModel
@foreach (var item in Model)
{
@Html.DropDownListFor(model => model.LicensedState, new SelectList(item.LicenseStates, item.LicenseState))
@Html.DropDownListFor(model => model.LicenseType, new SelectList(item.LicenseTypes, item.LicenseType))
}

您可以使用以下视图模型:
public class LicenseViewModel
{
public IEnumerable<SelectListItem> LicensedState { get; private set; }
public IEnumerable<SelectListItem> LicenseType { get; private set; }
public LicenseViewModel(string licensedState = null, string licenseType = null)
{
LicensedState = LicensedStatesProvider.All().Select(s=> new SelectListItem
{Selected = licensedState!= null && s == licensedState, Text = s, Value = s} );
LicenseType = LicenseTypesProvider.All().Select(t => new SelectListItem
{ Selected = licenseType != null && t == licenseType, Text = t, Value = t });
}
}
LicensedStatesProvider
和LicenseTypesProvider
只是获取所有LicensedStates和LicenseTypes的简单方法,由您决定如何获取它们。
在视图中,你会有这样的事情:
@foreach (var license in Model.Licenses)
{
//other stuff...
@Html.DropDownList("LicensedState", license.LicensedState)
@Html.DropDownList("LicenseType", license.LicenseType)
}
