我想用vs2010连上access数据库 做登陆界面用的

我连得是sql数据库 验证用户名密码是否正确 先在项目新建一个类 取名userinfo在类中定义：
public static string UserID;
public static string Password;
代码如下：
string sqlconn = "server = 220.162.131.160,1433;database = sqlwork;uid = sa;pwd = yxlbb520520";//数据库连接
string sqlqueryy = string.Format("select 账号,密码 from xs where 账号 = '{0}' and 密码 = '{1}'", textBox1.Text, textBox2.Text);
SqlConnection conn = new SqlConnection(sqlconn);
try
{
con.Open();
SqlCommand comm = new SqlCommand(sqlqueryy, con);
SqlDataReader ds = comm.ExecuteReader();
if (ds.Read())
{
userinfo1.UserID = ds[0].ToString();
userinfo1.Password = ds[1].ToString();
xs mf = new xs();
this.Hide();
mf.ShowDialog();
}
else
{
MessageBox.Show("用户名或密码错误！！！");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
con.Close();
}
