string consulta = "select aspnet_Membership.Password from aspnet_Users inner join aspnet_Membership on aspnet_Users.UserId=aspnet_Membership.UserId where aspnet_Users.UserName='chris'";
SqlCommand comando = new SqlCommand(consulta, cnn);
SqlDataReader lector;
try
{
cnn.Open();
lector = comando.ExecuteReader();
while (lector.Read())
{
contraseña = (string)lector["Password"];
}
Label1.Text = contraseña;
}
