namespace 连接局域网SQL服务器
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string str = "Server=192.168.0.86;Integrated Security=SSPI;database=pubs";
            SqlConnection conn = new SqlConnection(str);
            conn.Open();
            if (conn.State == ConnectionState.Open)
            {
                MessageBox.Show("打开数据库");
            }
            else
            {
                MessageBox.Show("数据库未打开");
            }
        }
    }
}
