检查后面的CheckBoxList项检查代码

Question

我有两张桌子：

1. has_service
2. 服务。

我想获取表1中的项目，然后将其与第二个表进行比较，看看是否匹配。该项目应显示为已选中。

我的代码有问题吗？

ListItem thItm;

//List all services in system DB.
var AllSrvs = from s in db.services                      
              select s;

//Get current request-services ID's
var reqSrvs = (from rs in db.has_services
               where rs.request_id == Convert.ToInt32(Request["reqID"].Trim())
               select rs.service_id).ToArray();

foreach (service se in AllSrvs)
{
    thItm = new ListItem();
    thItm.Text = se.service_name_en;
    thItm.Value = se.service_id.ToString();



    for (int i = 0; i < reqSrvs.Count();i++ )
    {

        if (reqSrvs[i] ==Convert.ToInt32( se.service_id))
        {
            thItm.Selected = true;

        }
        else
        {
            thItm.Selected = false;
        }               
    }

    RequestServicesCheckBoxList.Items.Add(thItm);
}

谢谢大家。 ：） 我想通了:) 问题与“其他”部分有关。  删除它，它现在正常工作......

 ListItem thItm;

//List all services in system DB.
var AllSrvs = from s in db.services                      
          select s;

//Get current request-services ID's
var reqSrvs = (from rs in db.has_services
           where rs.request_id == Convert.ToInt32(Request["reqID"].Trim())
           select rs.service_id).ToArray();

 foreach (service se in AllSrvs)
  {
thItm = new ListItem();
thItm.Text = se.service_name_en;
thItm.Value = se.service_id.ToString();



for (int i = 0; i < reqSrvs.Count();i++ )
{

    if (reqSrvs[i] ==Convert.ToInt32( se.service_id))
    {
        thItm.Selected = true;

    }
   // else
   // {
   //     thItm.Selected = false;
   // }               
}

RequestServicesCheckBoxList.Items.Add(thItm);

}
