c# checklistbox和数组比较问题?

Question

想判断checkBoxlist项内容和数组中的内容是否相同?如果相同checkBoxList项打勾,具体代码怎么写? 
这样写不行 
for (int j = 0; j  < CheckBoxList1.Items.Count; j++) 
            { 
                string[] supplierName = supplier.Split(',');   //supplier是从数据库取出的值 
                foreach (string i in supplierName) 
                { 
                    if (CheckBoxList1.Items[j].Text == i) 
                    { 
                        CheckBoxList1.Items[j].Selected = true; 
                    } 
                } 
            } 

Answer 1

没问题啊，我可以执行阿。我拷贝你的代码，放了个CheckBoxList1，里面加了３个ｃｈｅｃｋｂｏｘ
Ｔｅｘｔ分别是１，２，３．
string supplier = "1,2,5";
for (int j = 0; j < CheckBoxList1.Items.Count; j++)
{
     string[] supplierName = supplier.Split(',');   //supplier是从数据库取出的值  
      foreach (string i in supplierName)
     {
         if (CheckBoxList1.Items[j].Text == i)
         {
             CheckBoxList1.Items[j].Selected = true;
         }
     }
}  
执行后１和２被打上钩了。没错呀～～

完整代码:
protected void Page_Load(object sender, EventArgs e)
    {
        string supplier = string.Empty;        if (this.IsPostBack == false)
        {         
            string id = Request.QueryString["id"];
            SqlDataReader reader;
            reader = news.SelectCustomerId(id);
            while (reader.Read())
            {
                TextBox3.Text = reader["CIDCard"].ToString();
                TextBox4.Text = reader["CCompany"].ToString();
                TextBox6.Text = reader["CReceiver"].ToString();                TextBox1.Text = reader["CBillInfo"].ToString();
                TextBox2.Text = reader["CShipInfo"].ToString();                supplier = reader["CHasSuppliers"].ToString();
            }
            for (int j = 0; j < CheckBoxList1.Items.Count; j++)
            {
                string[] supplierName = ss.Split(',');   
                foreach (string i in supplierName)
                {
                    if (CheckBoxList1.Items[j].Text == i)
                    {
                        CheckBoxList1.Items[j].Selected = true;
                    }
                }
            }  
        }
    }
不报错,但读不出数据.checklist是绑定数据库的!!!!!!!!!!!!!!!!!!!!!!!
