            dataAdpt.Fill(ds);

            //注:此前要先填充DataGridView的列

            dtGrdVewDept.Rows.Clear();  //清空原有datagridview列表

           

            //将SQL的查询结果显示在datagridview中

            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)

            {

                dtGrdVewDept.Rows.Add(i+1,ds.Tables[0].Rows[i][0],ds.Tables[0].Rows[i][1]);

            }

        }

 

 

或直接:

            //返回查询结果

            DataSet ds = new DataSet();

            SqlDataAdapter dataAdpt = new SqlDataAdapter(searchStr, sqlCont);  //执行查询

            dataAdpt.Fill(ds);

            dataGridView1.DataSource=ds.Tables[0];         

            sqlCont.Close();
