C#的winform連接SQLserver數據庫實例代碼

創建一個winform窗口，添加兩個按鈕，一個datagridview控件和一個listview控件

連接和綁定datagridview控件的代碼

            SqlConnection con = new SqlConnection("server=.;uid=sa;pwd=ch19930310;database=student;");
            SqlDataAdapter dtp = new SqlDataAdapter("SELECT * FROM student", con);
            DataSet ds = new DataSet();
            dtp.Fill(ds);//填充數據集

            dataGridView1.DataSource = ds.Tables[0].DefaultView;   //連接數據表格，顯示數據
            con.Close();    //關閉OleDbConnection對象實例

 

連接和綁定listview控件的代碼

          SqlConnection con = new SqlConnection("server=.;uid=sa;pwd=ch19930310;database=student;");
            SqlDataAdapter dtp = new SqlDataAdapter("SELECT * FROM student", con);
            try
            {
                con.Open();
                SqlDataAdapter sda = new SqlDataAdapter("select st_id,st_name,st_birth,st_gender,st_address,st_tel,st_clid from student", con);
                DataSet ds = new DataSet();
                sda.Fill(ds);
                this.listView1.Columns.Add("學號", 80, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("姓名", 60, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("生日", 120, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("性別", 40, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("地址", 90, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("電話", 90, HorizontalAlignment.Center);//增加列標題
                this.listView1.Columns.Add("班級", 60, HorizontalAlignment.Center);//增加列標題
                listView1.View = View.Details;
                listView1.GridLines = true;//顯示網格線。
                string[] str = new string[7];
                foreach (DataRow row in ds.Tables[0].Rows)
                {

                    str[0] = row["st_id"].ToString();
                    str[1] = row["st_name"].ToString();
                    str[2] = row["st_birth"].ToString();
                    str[3] = row["st_gender"].ToString();
                    str[4] = row["st_address"].ToString();
                    str[5] = row["st_tel"].ToString();
                    str[6] = row["st_clid"].ToString();
                    ListViewItem item = new ListViewItem(str, 0);
                    listView1.Items.Add(item);

                }
            }
            catch (Exception er)
            {
                MessageBox.Show(er.ToString());
                con.Close();
            }

 

 

代碼很簡單，多看就理解了
