Question

我需要在HtmlHelper扩展中获取运行时初始化的模型的所有属性名称。我不能在帮助器中使用Type.GetType，因为它返回null。

型号代码：

public class SampleVm
{
    public object ResultObject { get; set; }

    public dynamic ResultDynamic { get; set; }
}

查看代码：

@Html.SampleResult(m => m. ResultDynamic)    // this is error, I don’t know why
@Html.SampleResult(m => m. ResultObject)   // this works

控制器代码：

public ActionResult Index()
{
    SearchVm vm = new SearchVm();
    vm.ResultObject = Type.GetType("MvcApplication4.Models.Sample.SampleMasterModel");
    vm.ResultDynamic = Type.GetType("MvcApplication4.Models.Sample.SampleMasterModel");
    return View("Index", vm);
}

HtmlHelper扩展代码：

public static HtmlString SearchResult<TModel, TProperty>(this HtmlHelper<TModel> html,
Expression<Func<TModel, TProperty>> expression)
{
    TModel model = html.ViewData.Model;
    String propertiesName = ?????
    // I want to get the properties name from ResultDynamic or ResultObject
    // I can found all properties from ResultDynamic in debug but don’t know how to 
    // get it.  For ResultDynamic, I don't know how to get the properties name.
    return new HtmlString();
}

我在AssemblyQualifiedName的帮助中使用Type.GetType。它解决了这些问题。

var type = Type.GetType("AssemblyQualifiedName of my Type");

var properties = type.GetProperties();
