我很难将我的计数代码显示在我的标签文本中.这是我的代码,请告诉我如何解决这个问题.

ordering_and_billing.dBase dBase = new ordering_and_billing.dBase();
var mydbconnection = new dBase.dbconnection();

string sql = "SELECT * FROM `order` WHERE eventdate='" + lbldte.Text + "'";

MySqlCommand cmd = new MySqlCommand(sql, mydbconnection.Connection);
mydbconnection.Connection.Open();
MySqlDataReader rdr = cmd.ExecuteReader();
if (rdr.HasRows)
{
    while (rdr.Read())
    {
        Int32 count = (Int32)cmd.ExecuteScalar();
        string disp = count.ToString();
        lblcount.Text = disp;
    }
}

伙计们如何在jquery中创建一个addclass和removeclass？我只是想在选择单选按钮时在div下创建一个活动的类名？我在下面附上了一些例子.
