原来处于选中状态的权限，取消后改怎么判断啊，一点小问题

Question

 protected void Button1_Click(object sender, EventArgs e)
    {
        
      IList<gannt.Resource> list =gannt.ProjectDAL.GetResourceByUid(0);
       
       ArrayList arrResource = gannt.ProjectDAL.GetResources(Convert.ToInt32(this.DropDownList1.SelectedItem.Value.ToString()));
       foreach (ListItem li in this.CheckBoxList1.Items)
       {
           if (li.Selected == true)
           {
               if (!arrResource.Contains(li.Text))//假如选定的项不在该角色已经拥有的列表中，则追加进来
               {
                   if (gannt.ProjectDAL.InsertResource(li.Text, Convert.ToInt32(this.DropDownList1.SelectedItem.Value.ToString())))
                   {
                       Response.Write("<script>alert('tianjai成功 ')</script>");
                   }
                   else
                   {
                       Response.Write("<script>alert('tianjia失败')</script>");
                   }               }
           }
           else
           {
               if (arrResource.Contains(li.Text))//假如不选的项在该角色已经拥有的列表中，则从列表中删除
               {
                   if (gannt.ProjectDAL.DeleteResourceByNameAndProjectUID(li.Text, Convert.ToInt32(this.DropDownList1.SelectedItem.Value.ToString())))
                   {
                       Response.Write("<script>alert('删除成功 ')</script>");
                   }
                   else
                   {
                       Response.Write("<script>alert('删除失败')</script>");
                   }
               }
           }
       }
        Response.Write("<script>alert('权限已生效！！')</script>");
    }不知道为什么else里的代码不执行，原来有的权限现在取消后，删除不掉，怎么回事，？这样写没错吧?

Answer 1

 else没有进去
设置一个断点看看，看是怎么走的

Answer 2

arrResource 这个是从那去过来的？

Answer 3

进不去？ 你把第一项设成false，跟一下看看

Answer 4

调试过了，没问题，问题在Arralist的contains这个方法有毛病

Answer 5

this.DropDownList1.SelectedItem.Value.ToString())
你的DropDownList1绑定放到page_load中试试
