请问这个代码我这样写，为什么到不出数据？我到底是写错了嘛？

[ybgolong]

SqlConnection MySqlConn = new SqlConnection("Data Source=XHL;Initial Catalog=HospitalOA;Integrated Security=True");
MySqlConn.Open();
SqlDataAdapter MySqlAdapter = new SqlDataAdapter("select * from Tb_HpOA_Dept",MySqlConn );
DataSet ds=new DataSet() ;
MySqlAdapter.Fill(ds, "DeptName"); // 然后在这个数据集里面传递参数2表的内容
for (int i = 0; i < ds.Tables[0].Rows.Count; i++) // 然后通过this.MyDataSet.Tables[0] 取得pub_info这个表 的Rows 行的Count 总数
{
this.comboBox1.Items.Add(ds.Tables[0].Rows[i][0]); // 来循环获取 当前数据集表的行的每一个行的第一个字段内容 添加到listbox里面
}
MySqlConn.Close();

没道理错啊````````` = =|||

"Data Source=XHL;Initial Catalog=HospitalOA;Integrated Security=True"没看懂

但是我改成我的都运行的起你是不是上面那句有错哦?

using System;
using System.Data;
using System.Data.SqlClient;

namespace Program
{
    class Db
    {
        public static void test()
        {
            SqlConnection MySqlConn = new SqlConnection("server=localhost;database=pubs;Integrated Security=true");
            MySqlConn.Open();
            SqlDataAdapter MySqlAdapter = new SqlDataAdapter("select   *   from   titles", MySqlConn);
            DataSet ds = new DataSet();
            MySqlAdapter.Fill(ds, "DeptName");          
            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)      
            {
                Console.WriteLine(ds.Tables[0].Rows[i][0]);   
            }
            MySqlConn.Close();
            Console.Read();
        }
        static void Main()
        {
            Db.test();
        }
   }
}
