数据库编程初

刚学到数据库编程,书上的文字、代码一大堆,是人没耐心,恼火!
一个简单的c#与数据库的连接,不过短短6行代码,我就弄了好一会儿,粗心!我把“Data Source”写成了“DataSource”,结果连不上,后来终于发现,
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace zsg
{
    public partial class Form1 : Form
    {
        private SqlConnection dbConnection;
        public Form1()
        {
            InitializeComponent();
        }
        //连接数据库
        private void button1_Click(object sender, EventArgs e)
        {
            string strConn;
            try
            {
                dbConnection = new SqlConnection();
                strConn = "Data Source=localhost;";
                strConn += "Initial Catalog=lunwen;";
                strConn += "Integrated Security=True";
                dbConnection.ConnectionString = strConn;
                
                label4.Text = "连接成功";
            }
            catch (Exception e3)
            {
                MessageBox.Show(e3.Message);
            }
        }
    }
}
 要记住教训,细工出好活。要有耐心。付出总有回报。
