ASP.NET MVC3应用程序与CMS功能

我正在学习ASP。. NET MVC3和做一个具有CMS功能的应用程序-但遇到了一些问题。

基本思想是所有的页面都连接到一个页面类型，而这个页面类型又有一组属性连接到它。

工作伟大，如果我只使用字符串值，但我希望能够键入所有属性(字符串，长字符串，XhtmlString，数字和TrueFalse)。

这是我想出来的模型。

public class Page
{
    public int PageId { get; set; }
    public int PageTypeId { get; set; }
    public string Name { get; set; }
    public PageType PageType { get; set; }
    public List<PropertyValues> Properties { get; set; }
}
public class PageType
{
    public int PageTypeId { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public string Controller { get; set; }
    public string Action { get; set; }
    public List<PropertyDefinition> Properties { get; set; }
}
public class PropertyDefinition
{
    public int PropertyDefinitionId { get; set; }
    public string Name { get; set; }
    public string Type { get; set; } // NormalString, LongString, XhtmlString, Number, TrueFalse
}
public class PropertyValues
{
    public int PropertyValueId { get; set; }
    public int PageId { get; set; }
    public int PropertyDefinitionId { get; set; }
    public string ValueNormalString { get; set; } // input=text
    public string ValueLongString { get; set; } // textarea
    public string ValueXhtmlString { get; set; } // tinymce
    public int ValueNumber { get; set; } // input=text
    public bool ValueTrueFalse { get; set; } // input=checkbox
    public PropertyDefinition Definition { get; set; }
}

基本上，当我在我的视图中我想要能够调用例如

@Page.Property["Whatever"]

并获取值。我被上面的问题困住了，不知道该怎么做。

编辑:

我从Russ那里得到的答案给了我一些帮助，我想出了下面的方法——这是有效的。我不知道是否有更好的解决办法。 有谁对我的解决方案有什么建议吗?

模型:

public class Page
{
    public int PageId { get; set; }
    public string Name { get; set; }
    public List<Property> Properties { get; set; }
    Dictionary<string, object> PageData = new Dictionary<string, object>();
    public object this[string name]
    {
        get
        {
            Property result = this.Properties.Find(
                delegate(Property p)
                {
                    return p.Name.Equals(name);
                });
            if (result != null)
            {
                switch (result.PropertyDefinition.Type)
                {
                    case "String":
                        return result.PropertyValue.ValueString;
                    case "LongString":
                        return result.PropertyValue.ValueLongString;
                    case "XHtmlString":
                        return result.PropertyValue.ValueXhtmlString;
                    case "Number":
                        return result.PropertyValue.ValueNumber;
                    case "Boolean":
                        return result.PropertyValue.ValueBoolean;
                    default:
                        return null;
                }
            }
            return null;
        }
        set
        {
            PageData[name] = value;
        }
    }
}
public class PropertyDefinition
{
    public int PropertyDefinitionId { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public string Type { get; set; }
}
public class PropertyValue
{
    public int PropertyValueId { get; set; }
    public int PropertyId { get; set; }
    public string ValueString { get; set; }
    public string ValueLongString { get; set; }
    public string ValueXhtmlString { get; set; }
    public int ValueNumber { get; set; }
    public bool ValueBoolean { get; set; }
}
public class Property
{
    public int PropertyId { get; set; }
    public string Name { get; set; }
    public string Caption { get; set; }
    public Page Page { get; set; }
    public PropertyDefinition PropertyDefinition { get; set; }
    public PropertyValue PropertyValue { get; set; }
    public int PageId { get; set; }
    public int PropertyDefinitionId { get; set; }
    public int PropertyValueId { get; set; }
}

控制器:

public class HomeController : Controller
{
    public String Index()
    {
        List<Property> properties = new List<Property>();
        Property propertyOne = new Property {
            PropertyId = 1,
            Name = "Title",
            Caption = "Page Title",
            TestPageId = 1,
            PropertyValue = new PropertyValue {
                PropertyValueId = 1,
                PropertyId = 1,
                ValueString = "This is the page title"
            },
            PropertyDefinition = new PropertyDefinition {
                PropertyDefinitionId = 1,
                Name = "String",
                Description = "String (< 255 characters)",
                Type = "String"
            }
        };
        properties.Add(propertyOne);
        Page CurrentPage = new Page
        {
            TestPageId = 1,
            Name = "Testpage",
            Properties = properties
        };

        return CurrentPage["Title"].ToString();
    }
}

@* set the model for the view to be of type Page *@
@model Page
@* to get the properties *@
@foreach(var prop in Model.Properties)
{
    <p>@prop.PageId</p>
