请问这个问题如何解决呢？非常感谢！

大家好！ 
    今天用Reflector 5.1.2.0 反编译了一段代码，遇到了一点问题。代码中if语句中的判断条件变成了"$$method0x60000ff",请问这个问题如何解决呢？非常感谢！ 
如下： if (((obj2 = strBtnAttributeType) != null) && ((obj2 = <PrivateImplementationDetails>.$$method0x60000ff-1[obj2]) != null))
页面全部原代码为： 
using System;
using System.Web.UI;
using XpShop6X.XpShop.Utility;
using XpShop6X.XpShop.WebUI;public partial class Admin_Actions : System.Web.UI.Page
{
    public ConfigDetails config = new ConfigDetails();
    public string strChallenge;
    public string strUKeyCode;
    public bool uKeyEnabled;
 private void InitializeComponent()
        {
            base.Load += new EventHandler(this.Page_Load);
        }        protected override void OnInit(EventArgs e)
        {
            this.InitializeComponent();
            base.OnInit(e);
        }        private void Page_Load(object sender, EventArgs e)
        {
            this.config = new ConfigDB().GetSystemConfig();
            this.strChallenge = WebUtils.GetUKeyChallengeString();
            this.uKeyEnabled = this.config.uKeyEnabled;
            this.strUKeyCode = this.config.UKeyCode;
            if (base.Request.QueryString["Action"] != null)
            {
                object obj2;
                ProductDB tdb = new ProductDB();
                ArticleCategoryDB ydb = new ArticleCategoryDB();
                LinkDB kdb = new LinkDB();
                ADDB addb = new ADDB();
                PollDB ldb = new PollDB();
                CategoryDB ydb2 = new CategoryDB();
                if (((obj2 = base.Request.QueryString["Action"].Trim()) != null) && ((obj2 = <PrivateImplementationDetails>.$$method0x600000d-1[obj2]) != null))
                {
                    switch (((int) obj2))
                    {
                        case 0:
                        {
                            int customFieldItemID = int.Parse(base.Request.QueryString["ItemID"].Trim());
                            tdb.DeleteCustomFieldItem(customFieldItemID);
                            base.Response.Redirect("ProductCustomField.aspx?productID=" + base.Request.QueryString["pid"]);
                            break;
                        }
                        case 1:
                            new CurrencyDB().SetDefaultCurrency(int.Parse(base.Request.QueryString["CID"].Trim()));
                            base.Response.Redirect("Currency.aspx?Action=Manage");
                            break;                        case 2:
                            ydb2.ChangeInNavStatus(int.Parse(base.Request.QueryString["CatID"].Trim()), base.Request.QueryString["Status"].Trim() != "True");
                            base.Response.Redirect("Category.aspx");
                            break;                        case 3:
                        ......
                           break;
                    }
                }
            }
        }
