让asp.net mvc的Action支持jQuery直接提交的javascript对象(2)

internal interface IUnvalidatedRequestValues
{
    NameValueCollection Form { get; }
    NameValueCollection QueryString {get;}
    string this[string key]{ get; }
}
 
internal delegate IUnvalidatedRequestValues UnvalidatedRequestValuesAccessor(ControllerContext controllerContext);
 
internal sealed class UnvalidatedRequestValuesWrapper : IUnvalidatedRequestValues
{
    private readonly UnvalidatedRequestValues _unvalidatedValues;
    public NameValueCollection Form
    {
        get
        {
            return this._unvalidatedValues.Form;
        }
    }
    public NameValueCollection QueryString
    {
        get
        {
            return this._unvalidatedValues.QueryString;
        }
    }
    public string this[string key]
    {
        get
        {
            return this._unvalidatedValues[key];
        }
    }
    public UnvalidatedRequestValuesWrapper(UnvalidatedRequestValues unvalidatedValues)
    {
        this._unvalidatedValues = unvalidatedValues;
    }
}
下面是用于支持FormValueProviderFactoryEx的另外几个对象的定义
public sealed class FormValueProviderEx : NameValueCollectionValueProvider
{
    public FormValueProviderEx(ControllerContext controllerContext)
        : this(controllerContext, new UnvalidatedRequestValuesWrapper(controllerContext.HttpContext.Request.Unvalidated()))
    {
 
    }
    internal FormValueProviderEx(ControllerContext controllerContext, IUnvalidatedRequestValues unvalidatedValues)
        : base(controllerContext.HttpContext.Request.Form, unvalidatedValues.Form, CultureInfo.CurrentCulture)
    {
 
    }
 
    public override ValueProviderResult GetValue(string key, bool skipValidation)
    {
        var result = base.GetValue(key, skipValidation);
        if (result == null)
