连接字符串

 protected void Button1_Click(object sender, EventArgs e)
        {
            string connectionString = "Data Source=JJ-PC;Initial Catalog=xTest;Integrated Security=True;user id=sa;Password=123";

            using (SqlConnection con = new SqlConnection(connectionString))
            {
                con.Open();
                //sql语句查询

                string commandString = "Select * from tb_schoose";

                SqlCommand cmd = new SqlCommand(commandString, con);
                System.Data.DataTable dt=cmd.ExecuteReader().GetSchemaTable();

                ExportDataTableToExcel(dt);
                //TT();
            }
